CBO InfiniBand Active Optical Cable QSFP-AOC-2M-CH-BO — QSFP+ to QSFP+, 2 m

The CBO InfiniBand Active Optical Cable QSFP-AOC-2M-CH-BO — QSFP+ to QSFP+, 2 m is a 2-meter active optical link designed for high-speed, short-reach connections in data centers and HPC environments. This Active Optical Cable (AOC) integrates an optical transceiver in a compact blue housing and provides a QSFP+ connector on each end for direct QSFP-to-QSFP connectivity. It is intended to replace copper twinax options where lower latency, immunity to electromagnetic interference and lower rack heat are priorities.

Advantages

The cable offers high data throughput and low latency suitable for InfiniBand networks while reducing susceptibility to electromagnetic interference common in dense installations. Its active optical design reduces power dissipation into racks compared with equivalent copper links and supports reliable short-range links between switches, servers and storage devices. The integrated transceivers simplify installation by providing a single, factory-terminated assembly without separate SFP/QSFP modules.

Suitable for

• Short-reach connections between QSFP+ ports on switches and routers
• Server-to-switch links in high-performance computing clusters
• Interconnects between storage arrays and host adapters
• Data center top-of-rack and spine-layer cabling

Key specifications

• Connector type: QSFP+ to QSFP+
• Cable type: Active Optical Cable (AOC) with integrated transceivers
• Length: 2 meters
• Application: InfiniBand high-speed short-reach links
• Performance characteristics: low latency, high data throughput
• Environmental traits: immunity to electromagnetic interference, reduced heat dissipation compared with copper

How to use

Install the cable by inserting each QSFP+ connector into the corresponding QSFP+ port until the connector latches. Ensure ports are compatible with active optical QSFP+ links and that the system firmware or switch firmware supports QSFP+ AOC devices. Route the cable to avoid tight bends and mechanical strain; maintain the specified bend radius for optical assemblies. Once connected, verify link status through the host or switch management interface to confirm the link is operating at the expected InfiniBand speed and lane configuration.

Recommendations

For optimal reliability, use the cable within recommended ambient temperature ranges and avoid repeated flexing near connector ends. Keep connectors clean and protect unused ends with dust caps. When replacing copper links with this active optical cable, verify power and firmware compatibility with your network equipment and consult equipment documentation for any required settings for QSFP+ AOC support.
