CBO InfiniBand Active Optical Cable QSFP-AOC-20M-IB-BO — 20 m

The CBO InfiniBand Active Optical Cable QSFP-AOC-20M-IB-BO — 20 m is a pre-terminated optical interconnect that delivers InfiniBand-compatible high-speed data transmission over a 20 metre reach using QSFP form-factor connectors. Built for short- to medium-range links between servers, switches and storage systems, this active optical cable integrates optical transceivers within the cable assembly to provide reliable fibre connectivity without separate SFP/QSFP modules. The design reduces electromagnetic interference and simplifies installation in dense data centre and high-performance computing (HPC) environments while maintaining low latency and consistent throughput.

Advantages

This 20 m active optical cable offers plug-and-play convenience with integrated optics, eliminating the need for additional transceiver purchases and reducing rack space usage. The QSFP connectors are compatible with InfiniBand interfaces and support high aggregate bandwidth suitable for modern fabrics. Because signal conversion occurs inside the cable, the solution reduces electrical crosstalk and EMI concerns common with copper cabling. The pre-terminated assembly streamlines deployment and replacement, supporting predictable performance in structured network topologies.

Suitable for

• Server-to-switch and switch-to-switch links in data centres
• High-performance computing clusters and interconnect fabrics
• Storage array interconnections and SAN backbones
• Short- to medium-reach fibre runs inside racks and between adjacent racks

Key specifications

• Form factor: QSFP active optical cable with integrated optics
• Reach: 20 metres suitable for short- to medium-range links
• Compatibility: InfiniBand-compatible high-speed interconnects
• Transmission medium: optical fibre with active conversion inside the cable assembly
• Typical use environment: data centre and HPC installations
• Installation: pre-terminated cable with plug-and-play connectors

How to use

Install the cable by inserting the QSFP connector ends into the corresponding QSFP ports on networking equipment, ensuring proper orientation and secure engagement. No separate transceivers are required; the cable’s integrated optics handle the electrical-to-optical signal conversion. Route the cable to avoid tight bends and mechanical stress, maintain the recommended bend radius for optical fibre, and secure the cable within trays or management panels as needed. Verify link status via the host or switch management interface and monitor throughput to confirm expected performance.

Recommendations

For reliable operation, maintain recommended bend radii and avoid sharp kinks or crushing forces. Use the 20 m length for connections within and between adjacent racks or across short data hall aisles. Confirm InfiniBand compatibility with your host and switch firmware and keep device firmware up to date for best interoperability. Handle connectors by the housing and keep end faces protected from dust; if cleaning is required, use fibre-safe cleaning tools.
