QDD-400G-DR4-S Overview
The Cisco QDD-400G-DR4-S module is a 400G QSFP-DD transceiver designed for data center interconnects over single mode fiber. Utilizing advanced PAM4 modulation and 4 fiber pairs in parallel, this module supports links up to 500m over SMF for 400GbE connectivity.
With support for 400GbE links as well as breakout to lower speeds, the QDD-400G-DR4-S provides flexibility in connectivity. It can break out to 4x100GbE operation, allowing connections to existing 100GbE infrastructure. An MPO-12 connector handles the 4 fiber pairs for ease of cabling between 400GbE ports.
Overall, the Cisco QDD-400G-DR4-S module enables high-speed 400GbE links over SMF with support for breakout to 100GbE. Its MPO connector and support on Cisco switches provides an interconnect solution for data centers migrating to 400G platforms.
