Description

Add-On QDD-400G-ZR-S-AO 400GBASE-ZR+ Coherent QSFP-DD Transceiver

Overview

The Add-On QDD-400G-ZR-S-AO is a TAA-compliant 400GBASE-ZR+ coherent QSFP-DD transceiver module. It is designed to provide high-speed, long-reach optical connectivity for data center interconnects (DCI) and metro networks. This module enables direct, pluggable 400GbE connections over DWDM systems, simplifying network architecture and reducing the need for separate transport equipment. Its design targets deployments requiring compliance with US government procurement regulations.

Compatibility

This transceiver is engineered as a direct replacement for Cisco's QDD-400G-ZR-S module. It is compatible with network switches, routers, and optical transport equipment that support the QSFP-DD form factor and the 400GBASE-ZR+ standard. Ensure your host device's firmware supports third-party optics for full functionality.

Installation Notes

Install the QDD-400G-ZR-S-AO module into a compatible QSFP-DD port. Ensure the host device is powered off during installation to prevent potential damage. Handle the module by its edges, avoiding contact with the optical connectors and pins. Clean optical connectors with appropriate tools before insertion. The module operates within standard data center temperature ranges.
