Designing a Coherent Transceiver

by admin

Coherent transmission has become a fundamental component of optical networks to address situations where direct detect technology cannot provide the required capacity and reach. While direct detect transmission only uses the amplitude of the light signal, coherent optical transmission manipulates three different light properties: amplitude, phase, and polarization. These additional degrees of modulation allow for

The Whats and Hows of Telcordia Standards

by admin

Before 1984, the world of telecom standards looked very different from how it does now. Such a world prominently featured closed systems like the one AT&T had in the United States. They were stable and functional systems but led to a sluggish pace of technology innovation due to the lack of competition. The breakup of
