400G 640km & 200G 2000km CFP2 Coherent

Overview

This CFP2 coherent module supports single-wave dual-mode operation at 400G (640km) and 200G (2000km). 400G uses PM-16QAM for exceptional spectral efficiency within a limited C-band, while 200G uses PM-QPSK for stronger noise tolerance and OSNR margins over ultra-long unrepeated spans. An integrated high-performance DSP performs real-time electronic dispersion compensation and polarization demux — no external DCM needed — with Flex-grid tunability.

Applications

Unrepeated metro-core and regional backbone transport, cross-city DCI for hyperscale data centers, national/provincial long-haul, and 5G core/backhaul.
