CBO InfiniBand Active Optical Cable QSFP-AOC-5M-NK-BO, QSFP to QSFP, 5 m

CBO InfiniBand Active Optical Cable QSFP-AOC-5M-NK-BO is a 5 m QSFP-to-QSFP active optical cable designed for short-reach, high-bandwidth connections in data centers and high-performance computing environments. The cable uses optical transmission to link QSFP ports on switches, servers and storage devices, delivering reliable data transfer while reducing electromagnetic interference and simplifying rack cabling.

Advantages

The active optical construction provides low-loss optical transmission suitable for multi-lane high-speed links, while maintaining signal integrity over a 5 metre distance. The QSFP-to-QSFP form factor offers hot-pluggable connectivity compatible with standard QSFP ports, enabling straightforward integration into existing network and compute infrastructure. Using fiber optics reduces susceptibility to EMI and allows denser cabling with less heat and weight compared with equivalent copper solutions.

Suitable for

• Short-reach high-speed links between QSFP ports in switches and routers
• Server-to-switch and switch-to-switch connections in data centers and HPC clusters
• Storage system interconnects requiring multi-lane bandwidth and low latency
• Rethinking rack cabling to reduce EMI and improve airflow

Key specifications

• Connector type: QSFP to QSFP optical connectors
• Length: 5 metres
• Transmission medium: active optical cable (fiber-optic)
• Use case: short-distance, multi-lane high-bandwidth links
• Compatibility: QSFP ports on network switches, servers and storage devices

How to use

Insert each QSFP end into the corresponding QSFP port on the devices to be connected, ensuring the connector latch engages. No external power supply is required beyond the host ports; the cable uses active optical electronics integrated into the QSFP ends. Verify link status via device LEDs or management interfaces and confirm expected data rates and lane alignment. When removing the cable, press the latch and pull straight to avoid stressing the connector.

Recommendations

For reliable operation, route the cable to avoid sharp bends and excessive tension; maintain the minimum bend radius specified by the manufacturer and keep connectors free of dust. Use AOC links for short-distance connections within racks or between adjacent racks; for longer distances consider pluggable transceivers with duplex or single-fiber patching. Check device compatibility lists if your equipment applies vendor-specific optical firmware or transceiver validation.
