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

CBO QSFP-AOC-5M-FR-BO is a 5 m active optical InfiniBand cable with QSFP connectors engineered for high-speed server, switch and storage interconnects. As an active optical cable (AOC), it delivers a fiber link that is electrically transparent and optimised for short-reach, high-bandwidth data centre connections. The compact QSFP-to-QSFP form factor enables plug-and-play installation with reduced electromagnetic interference and improved signal integrity compared with copper alternatives.

Advantages

This active optical InfiniBand cable offers low latency, stable throughput and high bandwidth suitable for demanding network and compute environments. The optical medium reduces susceptibility to electrical noise and enables higher-density port deployments by using thinner, more flexible cabling than equivalent copper assemblies. The QSFP connectors provide a standardized interface for interoperable connections between QSFP-equipped devices, while the AOC design eliminates the need for separate transceivers and fibre patching for simplified deployment.

Suitable for

• Server to switch interconnects in data centres
• High-performance computing (HPC) clusters using InfiniBand
• Storage area network (SAN) links requiring high bandwidth
• Short-reach rack-to-rack links where low latency is required

Key specifications

• Connector type: QSFP to QSFP
• Cable type: active optical cable (AOC)
• Length: 5 metres
• Application: InfiniBand high-speed interconnects
• Form factor: compact QSFP plug-and-play assembly
• Performance characteristics: low latency, high bandwidth, electrically transparent fibre link

How to use

Install the AOC by plugging each QSFP connector into the corresponding QSFP port on your devices while the equipment is powered down or following the vendor's hot-plug guidance. Ensure connectors are clean and ports are free of debris before insertion. Once connected, verify link status and data rates on the host devices and configure InfiniBand settings as required by your network topology. The integrated optical transceivers in the active cable remove the need for separate optical modules and fibre patching.

Recommendations

Route the cable to avoid sharp bends and maintain the manufacturer’s minimum bend radius. Use the 5 m length for short-reach connections within racks or between adjacent racks and choose AOC solutions when electrical isolation, reduced EMI and high-density cabling are important. For compatibility, confirm QSFP port support for InfiniBand on both connected devices.
