NeoPhotonics Charges Forward in 800G Transceiver Race: Week in Brief: 03/04/22

NeoPhotonics Corp. reported that it successfully used its indium phosphide-based coherent receiver and coherent modulators, coupled with its ultranarrow linewidth tunable lasers or distributed feedback lasers to demonstrate 120-Gbaud operation in applications ranging from 800-G LR (long reach) transmission to 400-G long haul transmission. The company said its 120-Gbaud components coupled with its ultranarrow linewidth external cavity “nano” tunable laser or distributed feedback lasers, along with concurrent DSP advances, could enable pluggable modules to operate at 800-G for applications within and between datacenters. NeoPhotonics also identified the possibility to extend the speed and reach of embedded telecom systems.
