Insights What are FEC and PCS, and Why do They Matter? November 16, 2022 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 Read more » coherent constellation shaping DSP DSPs error compensation FEC PCS power Proprietary reach reconfigurable standardized standards
