QDD-400G-SR8-S Overview
The Cisco QDD-400G-SR8-S module is a 400G QSFP-DD transceiver designed for high-density data center interconnects over multimode fiber. Utilizing advanced PAM4 modulation and 8 fiber pairs in parallel, this module can support link lengths up to 100m on OM4 fiber for 400GbE connectivity.
With support for 400GbE links as well as breakout to lower speeds, the QDD-400G-SR8-S provides flexibility in connectivity. It can break out to 2x200GbE or 8x50GbE operation, allowing connections to existing 100GbE infrastructure. An MPO-16 connector handles the 8 fiber pairs for ease of cabling between 400GbE ports.
Overall, the Cisco QDD-400G-SR8-S module enables high-speed 400GbE links over MMF with support for breakout to lower speeds. Its MPO connector and support on Cisco switches provides a versatile interconnect solution for data centers migrating to 400G platforms.
