Description

This 400G OpenZR+ QSFP-DD DCO modules based on DP-16QAM supporting extended C-band, polarization diversity coherent detection and advanced electronic link equalization. Chromatic dispersion compensation can be applied to the receive side of the demodulator. This module is managed utilizing the Two Wire Interface that is specified in the Common Management Interface Specification (CMIS).
