NeoPhotonics’ 400ZR+ QSFP-DD transceiver demos 400Gbps transmission over 800km in 75GHz-spaced DWDM

NeoPhotonics Corp of San Jose, CA, USA – a vertically integrated designer and manufacturer of silicon photonics and hybrid photonic integrated circuit (PIC)-based lasers, modules and subsystems for high-speed communications – says that it has demonstrated that its 400ZR+ QSFP-DD coherent pluggable transceiver can effectively transmit at a 400Gbps data rate over a distance of 800km in a 75GHz-spaced DWDM system with more than 3.5dB of optical signal-to-noise ratio (OSNR) margin in the optical signal…
