400g Coherent Qsfp Dwdm Transceiver

The module support for wide applications with Host interfaces: 400GAUI-8/100GUI-2. The Host interface conform to existing protocol standards and operate over standard physical layer specifications. The termination, mapping and/or aggregation of this signal is into an internal ZR frame structure. The ZR frame structure is then adapted to the CFEC engine and DSP framed for transmission over the coherent media Interface. The Host interface signaling conform to existing protocol and electrical standards as defined by IEEE 802.3TM-2018. The Host Interface compliant to very short reach high speed chip-to-module electrical interface CEI-56G- VSR-PAM4 for PAM4 coding.
