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

CBO InfiniBand Active Optical Cable QSFP-AOC-5M-NA-BO is a 5‑metre active optical link with QSFP connectors on both ends, designed for high‑speed InfiniBand interconnects in data centre environments. The cable delivers optical transmission characteristics typical of AOC technology while maintaining the QSFP form factor, enabling reliable short‑reach connections between switches, servers and storage arrays. By using optical fibres within an active cable assembly, it reduces electromagnetic interference and simplifies cable management compared with equivalent copper assemblies.

Advantages

The active optical construction provides high bandwidth and low latency suitable for InfiniBand fabrics while keeping power consumption and heat generation low. Its QSFP to QSFP termination preserves compatibility with QSFP ports on networking equipment and compute nodes. The 5‑metre length is intended for short‑reach topologies inside racks or between adjacent racks, offering a balance between reach and signal integrity. The cable also reduces susceptibility to electrical noise and ground‑loop issues common to copper cabling.

Suitable for

• Short‑reach InfiniBand links between switches in data centres
• Direct connections from servers to storage or accelerators with QSFP ports
• High‑performance computing clusters requiring low‑latency interconnects
• Rack‑level cabling where optical isolation and compact form factor are required

Key specifications

• Connector type: QSFP to QSFP
• Length: 5 metres
• Cable type: Active optical cable (AOC)
• Target application: InfiniBand short‑reach interconnects
• Form factor: QSFP compatible

How to use

Install the cable by aligning and inserting each QSFP connector into the corresponding QSFP port until the latch engages; ensure equipment is powered down or follows hot‑swap procedures recommended by the hardware vendor. Route the cable to avoid sharp bends and excessive tension, maintaining the manufacturer’s minimum bend radius for optical assemblies. Verify link status indicators on connected devices to confirm successful negotiation and link training appropriate for InfiniBand operation.

Recommendations

Store and handle the cable in a clean environment to avoid contamination of connector interfaces. Avoid exposing the cable to strong electromagnetic sources despite its optical nature, and follow rack‑level cable management practices to maintain airflow and prevent mechanical stress on connectors.
