CBO InfiniBand Active Optical Cable QSFP-AOC-10M-DL-BO 10 m QSFP+ to QSFP+

The CBO InfiniBand Active Optical Cable QSFP-AOC-10M-DL-BO 10 m QSFP+ to QSFP+ is a factory-terminated active optical link designed for short- to mid-range data centre interconnects. With QSFP+ form-factor connectors on both ends and a 10-metre OM link, this AOC provides low-latency, high-bandwidth connectivity for servers, switches and storage systems that require optical direct-attach cabling. The cable integrates transceivers and a fibre channel in a single assembly to simplify installation and reduce electromagnetic interference compared with copper alternatives.

Advantages

This active optical cable offers reduced link attenuation over longer distances compared to passive copper alternatives and maintains consistent signal integrity for high-speed InfiniBand traffic. The QSFP+ ends support compact port density and hot-pluggable operation, enabling easy deployment in dense rack environments. Being an optical direct-attach solution, the cable eliminates the need for separate transceiver modules and lowers power draw at the host interface while supporting reliable data transfer for latency-sensitive workloads.

Suitable for

• High-speed server-to-switch interconnects in data centres
• Switch-to-switch links in clustered networking topologies
• Storage array connections requiring low-latency fabric links
• Short- to mid-reach InfiniBand fabrics and HPC clusters

Key specifications

• Connector type: QSFP+ to QSFP+
• Length: 10 metres optical cable
• Medium: active optical fibre assembly
• Application: InfiniBand high-speed interconnects
• Latency: low-latency optical transmission suitable for HPC and storage fabrics
• Compatibility: designed for QSFP+ ports supporting InfiniBand protocols

How to use

Install the cable by inserting each QSFP+ connector into the corresponding QSFP+ port on the devices until the latch engages. Ensure devices are powered off or that hot-plug procedures recommended by the equipment vendor are followed if plugging into live systems. Route the cable to avoid sharp bends and maintain the manufacturer’s minimum bend radius; secure the cable to prevent strain on connector housings. After connection, verify link status on both endpoints and confirm data rate and fabric health through network management tools.

Recommendations

For reliable operation, avoid kinking or tightly coiling the cable and keep the optical ends covered when not in use. Use the cable within equipment environments that match the device specifications for temperature and humidity, and follow vendor guidance for firmware and driver compatibility with QSFP+ interfaces.
