Cisco QSFP-DD-400G-AOC5M 400G QSFP-DD Active Optical Cable 5m

The Cisco QSFP-DD-400G-AOC5M is a 400 Gigabit active optical cable (AOC) designed for high-speed data center interconnect applications. Built with integrated optical transceivers at both ends, this cable eliminates the need for separate pluggable modules and delivers native 400G throughput over a 5-meter reach within data center environments. The AOC architecture provides low latency, reduced power consumption compared to electrical alternatives, and simplified optical alignment for enterprise spine-and-leaf fabric deployments.

This cable supports 400GBASE-SR4 signaling and is engineered for rack-to-rack and row-within-data-center connectivity where flexibility and signal integrity are critical. The QSFP-DD form factor interfaces with standard QSFP-DD host ports found on contemporary 400G switches and network interface cards, enabling seamless integration into existing infrastructure without firmware modifications.

Deployed primarily in AI compute clusters, high-performance computing (HPC) environments, and next-generation data center fabrics, the AOC5M addresses the surge in 400G adoption by providing a cost-effective, low-touch alternative to discrete transceiver plus passive cable combinations for short-reach links.

Ideal for

• AI fabric interconnect between 400G spine switches and GPU compute nodes in the same data center row
• High-performance computing (HPC) cluster interconnect for tightly coupled compute and storage systems
• Rack-to-adjacent-rack 400G connectivity in hyper-scale data center spine-and-leaf architectures
• Machine learning training environments requiring low-latency, high-bandwidth intra-cluster links
• Enterprise data center north-south traffic aggregation on next-generation fabric switches
• Storage area network (SAN) modernization with 400G tier-1 switching fabric
