Last year, EFFECT Photonics announced the acquisition of the coherent optical digital signal processing (DSP) and forward error correction (FEC) business unit from the global communications company Viasat Inc. This also meant welcoming to the EFFECT Photonics family a new engineering team who will continue to work in the Cleveland area.
As EFFECT Photonics expands its influence into the American Midwest, it is interesting to dive deeper into Cleveland’s history with industry and technology. Cleveland has enjoyed a long story as a Midwest industrial hub, and as these traditional industries have declined, it is evolving into one of the high-tech hubs of the region.
Cleveland’s industrial sector expanded significantly in the 19th century because of the city’s proximity to several essential resources and transportation routes: coal and iron ore deposits, the Ohio and Erie Canal, and the Lake Erie railroad. For example, several steel mills, such as the Cleveland Rolling Mill Company and the Cleveland Iron and Steel Company, emerged because of the city’s proximity to Lake Erie, facilitating the transportation of raw materials and goods.
Building on the emerging iron and steel industries, heavy equipment production also found a home in Cleveland. Steam engines, railroad equipment, and other forms of heavy machinery were all manufactured in great quantities in the city.
Cleveland saw another massive boost to its industrial hub status with the birth of the Standard Oil Company in 1870. At the peak of its power, Standard Oil was the largest petroleum company in the world, and its success made its founder and head, John D. Rockefeller, one of the wealthiest men of all time. This history with petroleum also led to the emergence of Cleveland’s chemicals and materials industry.
Many immigrants moved to Cleveland, searching for work in these expanding industries, contributing to the city’s rapid population boom. This growth also prompted the development of new infrastructure like roads, railways and bridges to accommodate the influx of people.
Several important electrical and mechanical equipment manufacturers, including the Bendix Corporation, the White Motor Company, and the Western Electric Company (which supplied equipment to the US Bell System), also established their headquarters in or around Cleveland in the late 19th and early 20th century.
In the second half of the 20th century, Cleveland’s traditional industries, such as steel and manufacturing in Cleveland began to collapse. As was the case in many other great American manufacturing centers, automation, globalization, and other socioeconomic shifts all had a role in this decline. The demise of Cleveland’s core industries was a significant setback, but the city has made substantial efforts in recent years to diversify its economy and grow in new technology and healthcare areas.
For example, the Cleveland Clinic is one of the leading US academic medical centers, with pioneering medical breakthroughs such as the first coronary artery bypass surgery and the first face transplant in the United States. Institutions like theirs or the University Hospitals help establish Cleveland as a center for healthcare innovation.
Cleveland is also trying to evolve as a high-tech hub that attracts new workers and companies, especially in software development. Companies are attracted by the low office leasing and other operating costs, while the affordable living costs attract workers. As reported by the real estate firm CBRE, Cleveland’s tech workforce grew by 25 percent between 2016 and 2021, which was significantly above the national average of 12.8 percent.
As Cleveland’s history as a tech hub continues, EFFECT Photonics is excited to join this emerging tech environment. Our new DSP team will find its new home in the Wagner Awning building in the Tremont neighborhood of Cleveland’s West Side.
This building was erected in 1895 and hosted a sewing factory that manufactured everything from tents and flotation devices for American soldiers and marines to awnings for Cleveland buildings. When the Ohio Awning company announced its relocation in 2015, this historic building began a redevelopment process to become a new office and apartment space.
EFFECT Photonics is proud to become a part of Cleveland’s rich and varied history with industry and technology. We hope our work can help develop this city further as a tech hub and attract more innovators and inventors to Cleveland.

-New pTLA to offer industry-best combination of size, affordability, and performance to meet the demand for 100G coherent at the edge
EINDHOVEN, The Netherlands—EFFECT Photonics, a leading developer of highly integrated optical solutions, announced today the development of a new Pico Tunable Laser Assembly (pTLA) to address the growing demand for 100G coherent transceivers in access networks. Tunable lasers are a core component of optical systems enabling dense wavelength division multiplexing (DWDM) which allows network operators to expand their network capacity without expanding the existing fiber infrastructure. Purposely designed for the optical network edge, EFFECT Photonics new pTLA supports both commercial- and industrial-temperature (C-temp and I-temp) operating ranges and offers an ideal combination of power, cost, and size to enable a transceiver form-factors to upgrade the existing infrastructure to a scalable 100 Gbps coherent solution.
According to a recent Heavy Reading survey, 75% of operators believe that 100G coherent pluggable optics will be used extensively in their edge and access evolution strategy. However, market adoption has yet to materialize since affordable and power-efficient 100ZR-based products are currently not available due to stringent size and power consumption requirements that cannot be fulfilled by today’s tunable laser solutions. Designed specifically to address the 100G coherent network edge, EFFECT Photonics’ pTLA will allow coherent pluggables to be deployed more easily and cost effectively in the access domain and will feature optimal laser performance, size and power consumption for a standard QSFP28 form-factor. Furthermore, EFFECT Photonics’ new pTLA utilizes the existing microelectronics ecosystem to allow manufacturing at scale as well as complementary coherent products and services, such as DSPs for those providers in need of a complete transceiver solution.
“Today’s operators need an network edge aggregation strategy that offers the best combination of capacity, cost-effectiveness, and performance to evolve network access effectively, and 100G coherent pluggable optics offer just that, EFFECT Photonics’ new Pico Tunable Laser Assembly will be the only purpose designed tunable laser assembly today to serve this emerging market. helping to easily scale up network edge aggregation capacity and benefit from coherent technology.”

Precision farming is essential in a world with over 10 billion people by 2050 and a food demand that is expanding at an exponential pace. The 2019 World Resources Report from the World Economic Forum warns that at the current level of food production efficiency, feeding the world in 2050 would require “clearing most of the world’s remaining forests, wiping out thousands more species, and releasing enough greenhouse gas emissions to exceed the 1.5°C and 2°C warming targets enshrined in the Paris Agreement – even if emissions from all other human activities were entirely eliminated.”
Technology can help the agrifood industry improve efficiency and meet these demands by combining robotics, machine vision, and small sensors to precisely and automatically determine the care needed by plants and animals in our food supply chain. This approach helps control and optimize food production, resulting in more sustainable crops, higher yields, and safer food.
Sensors based on integrated photonics can enable many of these precision farming applications. Photonic chips are lighter and smaller than other solutions so they can be deployed more easily in these agricultural use cases. The following article will provide examples of how integrated photonics and optical technology can add value to the agriculture and food industries.
The Netherlands is such a small country that if it were a US state, it would be among the ten smallest states, with a land area between West Virginia and Maryland. Despite its size, the Food and Agriculture Organization of the United Nations (FAO) ranked the Netherlands as the second largest exporter of food in the world by revenue in 2020, only behind the Americans and ahead of countries like Germany, China, or Brazil. These nations have tens or hundreds of times more arable land than the Dutch. Technology is a significant reason for this achievement, and the Dutch are arguably the most developed nation in the world regarding precision farming.
The hub of Dutch agrifood research and development is called the Food Valley, centered in the municipality of Wageningen in Gelderland province. In this area, many public and private R&D initiatives are carried out jointly with Wageningen University, a world-renowned leader in agricultural research.
When interviewed last year, Harrij Schmeitz, Director of the Fruit Tech Campus in Geldermalsen, mentions the example of a local fruit supplier called Fruitmasters. They employ basic cameras to snap 140 photographs of each apple that travels through the sorting conveyor, all within a few milliseconds. These photographs are used to automatically create a 3D model and help the conveyor line filter out the rotten apples before they are packaged for customers. This process was done manually in the past, so this new 3D mapping technology significantly improves efficiency.
These techniques are not just constrained to Gelderland, of course. Jacob van den Borne is a potato farmer from Reusel in the province of North Brabant, roughly a half-hour drive from EFFECT Photonics’ Eindhoven headquarters. Van den Borne’s farm includes self-driving AVR harvesters (shown in the video below), and he has been using drones in his farms since 2011 to photograph his fields and study the soil quality and farming yield.
The drone pictures are used to create maps of the fields, which then inform farming decisions. Van den Borne can study the status of the soil before farming, but even after crops have sprouted, he can study which parts of the field are doing poorly and need more fertilization. These measures prevent food waste and the overuse of fertilizer and pesticides. For example, Van den Borne’s farms have eliminated pesticide chemicals in their greenhouses while boosting their yield. The global average yield of potatoes per acre is around nine tons, but his farms yield more than 20 tons per acre!
If you want to know more about Van den Borne and his use of technology and data, you can read this article.
Artificial lighting is a frequent requirement of indoor plant production facilities to increase production and improve crop quality. Growers are turning to LED lighting because it is more efficient than traditional incandescent or fluorescent systems at converting electricity to light. LED lights are made through similar semiconductor manufacturing processes to photonics chips.
LED lighting also provides a greater variety of colors than the usual yellow/orange glow. This technology allows gardeners to pick colors that match each plant’s demands from seedlings through cultivation, unlike high-pressure sodium or other traditional lighting systems. Different colors of visible light create different chlorophyll types in plants, so LED lights can be set to specific colors to provide the best chlorophyll for each development stage.
For example, suppose you roam around the Westland municipality of the Netherlands. You might occasionally catch a purple glow in the night skies, which has nothing to do with UFOs or aliens wanting to abduct you. As explained by Professor Leo Marcelis of Wageningen University (see the above video), researchers have found that red light is very good for plant growth, and mixing it with five to ten percent blue light gives even better results. Red and blue are also the most energy-efficient colors for LEDs, which helps reduce energy consumption even more. As a result, the farmers can save on light and energy use while the environment profits too.
Modern farmers like Jacob van den Borne collect a large quantity of sensor data, which allows them to plan and learn how to provide plants with the perfect amount of water, light, and nutrients at the proper moment. Farmers can use these resources more efficiently and without waste thanks to this sensor information.
For example, Van den Borne uses wireless, Internet-of-Things sensors from companies like Sensoterra (video below) to gauge the soil’s water level. As we speak, researchers in the OnePlanet Research Center, a collaboration including the Imec R&D organization and Wageningen University, are developing nitrogen sensors that run on optical chips and can help keep nitrogen emissions in check.
These sensors will be connected to local servers and the internet for faster data transfer, so many of the issues and photonics solutions discussed in previous articles about the cloud edge and access networks are also relevant for agrifood sensors. Thus, improving optical communication networks will also impact the agrifood industry positively.
In a future of efficient high-tech and precision farming, optics and photonics will play an increasingly important role.
Optical sensors on a chip can be fast, accurate, small, and efficient. They will provide food producers with plenty of data to optimize their production processes and monitor the environmental impact of food production. Novel lighting methods can reduce the energy consumption of greenhouses and other indoor plant facilities. Meanwhile, photonics will also be vital to improving the capacity of the communications networks that these sensors run in.
With photonics-enabled precision processes, the agrifood industry can improve yields and supply, optimize resource use, reduce waste throughout the value chain, and minimize environmental impact.

On October 21st, 1983, the General Conference of Weights and Measures adopted the current value of the speed of light at 299,792.458 km/s. To commemorate this milestone, hundreds of optics and photonics companies, organizations, and institutes all over the world organize activities every year on this date to celebrate the Day of Photonics and how this technology is impacting our daily lives.
At EFFECT Photonics, we want to celebrate the Day of Photonics by answering some commonly asked questions about photonics and its impact on the world.
Photonics is the study and application of photon (light) generation, manipulation, and detection, often aiming to create, control, and sense light signals.
The term photonics emerged in the 60s and 70s with the development of the first semiconductor lasers and optical fibers. Its goals and even the name “photonics” are born from its analogy with electronics: photonics aims to generate, control, and sense photons (the particles of light) in similar ways to how electronics does with electrons (the particles of electricity).
Photonics can be applied in many ways. For the Day of Photonics, we will explore two categories:
Light is the fastest information carrier in the universe and can transmit this information while dissipating less heat and energy than electrical signals. Thus, photonics can dramatically increase the speed, reach, and flexibility of communication networks and cope with the ever-growing demand for more data. And it will do so at a lower energy cost, decreasing the Internet’s carbon footprint.
A classic example is optical fiber communications. The webpage you are reading was originally a stream of 0 and 1s that traveled through an optical fiber to reach you.
Outside of optical fibers, photonics can also deliver solutions beyond what traditional radio communications can offer. For example, optical transmission over the air could handle links between different sites of a mobile network, links between cars, or to a satellite out in space. At some point, we may even see the use of Li-Fi, a technology that replaces indoor Wi-Fi links with infrared light.
There are multiple sensing application markets, but their core technology is the same. They need a small device that sends out a known pulse of light, accurately detects how the light comes back, and calculates the properties of the environment from that information. It’s a simple but quite powerful concept.
This concept is already being used to implement LIDAR systems that help self-driving cars determine the location and distance of people and objects. However, there is also potential to use this concept in medical and agri-food applications, such as looking for undesired growths in the human eye or knowing how ripe an apple is.
No, each technology has its strengths.
When transmitting information from point A to B, photonics can do it faster and more efficiently than electronics. For example, optical fiber can transmit information at the speed of light and dissipate less heat than electric wires.
On the other hand, since electricity can be manipulated at the nanometer level more easily than light, electronics are usually better for building computers. There are some specific areas where photonic computers could outperform traditional electronic ones, especially given the rise of quantum computers that can be made with photonic components. However, most computer products will remain electronic for the foreseeable future.
Thus, photonics is not expected to replace electronics but to collaborate and integrate strongly with it. Most future applications will involve photonic systems transmitting or sensing information then processed by electronic computers.

Like every other telecom network, cable networks had to change to meet the growing demand for data. These demands led to the development of hybrid fiber-coaxial (HFC) networks in the 1990s and 2000s. In these networks, optical fibers travel from the cable company hub and terminate in optical nodes, while coaxial cable connects the last few hundred meters from the optical node to nearby houses. Most of these connections were asymmetrical, giving customers more capacity to download data than upload.
That being said, the way we use the Internet has evolved over the last ten years. Users now require more upstream bandwidth thanks to the growth of social media, online gaming, video calls, and independent content creation such as video blogging. The DOCSIS standards that govern data transmission over coaxial cables have advanced quickly because of these additional needs. For instance, full-duplex transmission with symmetrical upstream and downstream channels is permitted under the most current DOCSIS 4.0 specifications.
Fiber-to-the-home (FTTH) systems, which bring fiber right to the customer’s door, are also proliferating and enabling Gigabit connections quicker than HFC networks. Overall, extending optical fiber deeper into communities (see Figure 1 for a graphic example) is a critical economic driver, increasing connectivity for the rural and underserved. These investments also lead to more robust competition among cable companies and a denser, higher-performance wireless network.
Passive optical networks (PONs) are a vital technology to cost-effectively expand the use of optical fiber within access networks and make FTTH systems more viable. By creating networks using passive optical splitters, PONs avoid the power consumption and cost of active components in optical networks such as electronics and amplifiers. PONs can be deployed in mobile fronthaul and mid-haul for macro sites, metro networks, and enterprise scenarios.
Despite some success from PONs, the cost of laying more fiber and the optical modems for the end users continue to deter carriers from using FTTH more broadly across their networks. This cost problem will only grow as the industry moves into higher bandwidths, such as 50G and 100G, requiring coherent technology in the modems.
Therefore, new technology and manufacturing methods are required to make PON technology more affordable and accessible. For example, wavelength division multiplexing (WDM)-PON allows providers to make the most of their existing fiber infrastructure. Meanwhile, simplified designs for coherent digital signal processors (DSPs) manufactured at large volumes can help lower the cost of coherent PON technology for access networks.
Previous PON solutions, such as Gigabit PON (GPON) and Ethernet PON (EPON), used time-division multiplexing (TDM) solutions. In these cases, the fiber was shared sequentially by multiple channels. These technologies were initially meant for the residential services market, but they scale poorly for the higher capacity of business or carrier services. PON standardization for 25G and 50G capacities is ready but sharing a limited bitrate among multiple users with TDM technology is an insufficient approach for future-proof access networks.
This WDM-PON uses WDM multiplexing/demultiplexing technology to ensure that data signals can be divided into individual outgoing signals connected to buildings or homes. This hardware-based traffic separation gives customers the benefits of a secure and scalable point-to-point wavelength link. Since many wavelength channels are inside a single fiber, the carrier can retain very low fiber counts, yielding lower operating costs.
WDM-PON has the potential to become the unified access and backhaul technology of the future, carrying data from residential, business, and carrier wholesale services on a single platform. We discussed this converged access solution in one of our previous articles. Its long-reach capability and bandwidth scalability enable carriers to serve more customers from fewer active sites without compromising security and availability.
Migration to the WDM-PON access network does require a carrier to reassess how it views its network topology. It is not only a move away from operating parallel purpose-built platforms for different user groups to one converged access and backhaul infrastructure. It is also a change from today’s power-hungry and labor-intensive switch and router systems to a simplified, energy-efficient, and transport-centric environment with more passive optical components.
As data demands continue to grow, direct detect optical technology used in prior PON standards will not be enough. The roadmap for this update remains a bit blurry, with different carriers taking different paths. For example, future expansions might require using 25G or 50G transceivers in the cable network, but the required number of channels in the fiber might not be enough for the conventional optical band (the C-band). Such a capacity expansion would therefore require using other bands (such as the O-band), which comes with additional challenges. An expansion to other optical bands would require changes in other optical networking equipment, such as multiplexers and filters, which increases the cost of the upgrade.
An alternative solution could be upgrading instead to coherent 100G technology. An upgrade to 100G could provide the necessary capacity in cable networks while remaining in the C-band and avoiding using other optical bands. This path has also been facilitated by the decreasing costs of coherent transceivers, which are becoming more integrated, sustainable, and affordable. You can read more about this subject in one of our previous articles.
For example, the renowned non-profit R&D center CableLabs announced a project to develop a symmetric 100G Coherent PON (C-PON). According to CableLabs, the scenarios for a C-PON are many: aggregation of 10G PON and DOCSIS 4.0 links, transport for macro-cell sites in some 5G network configurations, fiber-to-the-building (FTTB), long-reach rural scenarios, and high-density urban networks.
CableLabs anticipates C-PON and its 100G capabilities to play a significant role in the future of access networks, starting with data aggregation on networks that implement a distributed access architecture (DAA) like Remote PH. You can learn more about these networks here.
The main challenge of C-PON is the higher cost of coherent modulation and detection. Coherent technology requires more complex and expensive optics and digital signal processors (DSPs). Plenty of research is happening on simplifying these coherent designs for access networks. However, a first step towards making these optics more accessible is the 100ZR standard.
100ZR is currently a term for a short-reach (~80 km) coherent 100Gbps transceiver in a QSFP pluggable size. Targeted at the metro edge and enterprise applications that do not require 400ZR solutions, 100ZR provides a lower-cost, lower-power pluggable that also benefits from compatibility with the large installed base of 50 GHz and legacy 100 GHz multiplexer systems.
Another way to reduce the cost of PON technology is through the economics of scale, manufacturing pluggable transceiver devices at a high volume to drive down the cost per device. And with greater photonic integration, even more, devices can be produced on a single wafer. This economy-of-scale principle is the same behind electronics manufacturing, which must be applied to photonics.
Researchers at the Technical University of Eindhoven and the JePPIX consortium have modeled how this economy of scale principle would apply to photonics. If production volumes can increase from a few thousand chips per year to a few million, the price per optical chip can decrease from thousands of Euros to tens of Euros. This must be the goal of the optical transceiver industry.
Integrated photonics and volume manufacturing will be vital for developing future passive optical networks. PONs will use more WDM-PON solutions for increased capacity, secure channels, and easier management through self-tuning algorithms.
Meanwhile, PONs are also moving into incorporating coherent technology. These coherent transceivers have been traditionally too expensive for end-user modems. Fortunately, more affordable coherent transceiver designs and standards manufactured at larger volumes can change this situation and decrease the cost per device.

Optical fiber and dense wavelength division multiplex (DWDM) technology are moving towards the edges of networks. In the case of new 5G networks, operators will need more fiber capacity to interconnect the increased density of cell sites, often requiring replacing legacy time-division multiplexing transmission with higher-capacity DWDM links. In the case of cable and other fixed access networks, new distributed access architectures like Remote PHY free up ports in cable operator headends to serve more bandwidth to more customers.
A report by Deloitte summarizes the reasons to expand the reach and capacity of optical access networks: “Extending fiber deeper into communities is a critical economic driver, promoting competition, increasing connectivity for the rural and underserved, and supporting densification for wireless.”
To achieve such a deep fiber deployment, operators look to DWDM solutions to expand their fiber capacity without the expensive laying of new fiber. DWDM technology has become more affordable than ever due to the availability of low-cost filters and SFP transceiver modules with greater photonic integration and manufacturing volumes. Furthermore, self-tuning technology has made the installation and maintenance of transceivers easier and more affordable.
Despite the advantages of DWDM solutions, their price still causes operators to second-guess whether the upgrade is worth it. For example, mobile fronthaul applications don’t require all 40, 80, or 100 channels of many existing tunable modules. Fortunately, operators can now choose between narrow- or full-band tunable solutions that offer a greater variety of wavelength channels to fit different budgets and network requirements.
Let’s look at what happens when a fixed access network needs to migrate to a distributed access architecture like Remote PHY.
A provider has a legacy access network with eight optical nodes, and each node services 500 customers. To give higher bandwidth capacity to these 500 customers, the provider wants to split each node into ten new nodes for fifty customers. Thus, the provider goes from having eight to eighty nodes. Each node requires the provider to assign a new DWDM channel, occupying more and more of the optical C-band. This network upgrade is an example that requires a fullband tunable module with coverage across the entire C-band to provide many DWDM channels with narrow (50 GHz) grid spacing.
Furthermore, using a fullband tunable module means that a single part number can handle all the necessary wavelengths for the network. In the past, network operators used fixed wavelength DWDM modules that must go into specific ports. For example, an SFP+ module with a C16 wavelength could only work with the C16 wavelength port of a DWDM multiplexer. However, tunable SFP+ modules can connect to any port of a DWDM multiplexer. This advantage means technicians no longer have to navigate a confusing sea of fixed modules with specific wavelengths; a single tunable module and part number will do the job.
Overall, fullband tunable modules will fit applications that need a large number of wavelength channels to maximize the capacity of fiber infrastructure. Metro transport or data center interconnects (DCIs) are good examples of applications with such requirements.
The transition to 5G and beyond will require a significant restructuring of mobile network architecture. 5G networks will use higher frequency bands, which require more cell sites and antennas to cover the same geographical areas as 4G. Existing antennas must upgrade to denser antenna arrays. These requirements will put more pressure on the existing fiber infrastructure, and mobile network operators are expected to deliver their 5G promises with relatively little expansion in their fiber infrastructure.
DWDM solutions will be vital for mobile network operators to scale capacity without laying new fiber. However, operators often regard traditional fullband tunable modules as expensive for this application. Mobile fronthaul links don’t need anything close to the 40 or 80 DWDM channels of a fullband transceiver. It’s like having a cable subscription where you only watch 10 out of the 80 TV channels.
This issue led EFFECT Photonics to develop narrowband tunable modules with just nine channels. They offer a more affordable and moderate capacity expansion that better fits the needs of mobile fronthaul networks. These networks often feature nodes that aggregate two or three different cell sites, each with three antenna arrays (each antenna provides 120° coverage at the tower) with their unique wavelength channel. Therefore, these aggregation points often need six or nine different wavelength channels, but not the entire 80-100 channels of a typical fullband module.
With the narrowband tunable option, operators can reduce their part number inventory compared to grey transceivers while avoiding the cost of a fullband transceiver.
The number of channels in a tunable module (up to 100 in the case of EFFECT Photonics fullband modules) can quickly become overwhelming for technicians in the field. There will be more records to examine, more programming for tuning equipment, more trucks to load with tuning equipment, and more verifications to do in the field. These tasks can take a couple of hours just for a single node. If there are hundreds of nodes to install or repair, the required hours of labor will quickly rack up into the thousands and the associated costs into hundreds of thousands.
Self-tuning allows technicians to treat DWDM tunable modules the same way they treat grey transceivers. There is no need for additional training for technicians to install the tunable module. There is no need to program tuning equipment or obsessively check the wavelength records and tables to avoid deployment errors on the field. Technicians only need to follow the typical cleaning and handling procedures, plug the transceiver, and the device will automatically scan and find the correct wavelength once plugged. This feature can save providers thousands of person-hours in their network installation and maintenance and reduce the probability of human errors, effectively reducing capital and operational expenditures.
Self-tuning algorithms make installing and maintaining narrowband and fullband tunable modules more straightforward and affordable for network deployment.
Fullband self-tuning modules will allow providers to deploy extensive fiber capacity upgrades more quickly than ever. However, in use cases such as mobile access networks where operators don’t need a wide array of DWDM channels, they can opt for narrowband solutions that are more affordable than their fullband alternatives. By combining fullband and narrowband solutions with self-tuning algorithms, operators can expand their networks in the most affordable and accessible ways for their budget and network requirements.
