NeoPhotonics Announces Demonstration of 400 Gbps Transmission Over 800km in a 75GHz-spaced DWDM System by Its QSFP-DD Pluggable Coherent Module

SAN JOSE, Calif.--(BUSINESS WIRE)--NeoPhotonics Corporation (NYSE: NPTN), a leading developer of silicon photonics and advanced hybrid photonic integrated circuit-based lasers, modules and subsystems for bandwidth-intensive, high speed communications networks, today announced that it has demonstrated that its 400ZR+ QSFP-DD coherent pluggable transceiver can effectively transmit at a 400 Gbps data rate over a distance of 800 km in a 75GHz-spaced DWDM system with more than 3.5 dB of OSNR margin in the optical signal. This 400ZR+ coherent pluggable transceiver module is based on NeoPhotonics high performance coherent optics and its ultra-pure color tunable laser, and achieves a reach of 800 km while staying within the power consumption envelop of the QSFP-DD module’s power specification. The Company believes these 400ZR+ QSFP-DD modules will find wide application in the Cloud-based Metro 5G networks, and will extend use cases for IP over DWDM into metro-core and regional networks.
