BlueOptics CBL-QSFP+AOC-5M-BO InfiniBand/fibre optic cable 5m Male/Male

The BlueOptics CBL-QSFP+AOC-5M-BO InfiniBand/fibre optic cable is a 5-metre active optical cable with QSFP connectors on both ends, designed for high-speed links in data centres and network racks. It supports multimode fibre transmission with integrated transmitter and receiver modules in each connector and conforms to QSFP/MSA physical interfaces. The cable is intended for short-reach 40 Gbps class applications where a compact, low-latency optical link is required between compatible QSFP ports.

Advantages

This active optical cable provides stable 40G class transmission over 5 metres with low insertion loss and immunity to electromagnetic interference compared with copper alternatives. The QSFP-to-QSFP form factor simplifies installation into switches, routers and storage devices that accept QSFP modules. Integrated transceivers reduce the need for separate SFP/QSFP transceiver purchases and ensure matched transmitter/receiver performance for reliable signal integrity.

Suitable for

• Server-to-switch and switch-to-switch connections within racks and across short distances in data centres
• High-performance computing clusters using InfiniBand or Ethernet at 40 Gbps
• Storage networking and Fibre Channel over Ethernet links requiring multimode optical cabling

Key specifications

• Cable type: Active optical cable (AOC) with multimode fibre
• Connector type: QSFP male to QSFP male
• Nominal data rate: up to 40 Gbit/s aggregated
• Length: 5 metres
• Application protocols: Ethernet, InfiniBand, Fibre Channel over Ethernet, SDH/SONET compatible topologies
• Form factor: QSFP compliant with MSA physical interface

How to use

Power off or follow hot-plug guidelines of your network devices, then insert each QSFP connector into the corresponding QSFP port until the latch engages. Ensure the cable route avoids tight bends and mechanical strain; maintain the manufacturer’s minimum bend radius for multimode fibre. After connection, verify link status on the network devices and configure port speed and protocol as required by your switch, router or host adapter. If using vendor-specific hardware, confirm compatibility with the device firmware and supported cable types before deployment.

Usage recommendations

Use this 5 m QSFP AOC for short-reach, high-throughput links inside racks or between adjacent racks. Avoid running the cable near sources of excessive heat or sharp edges, and inspect connectors for contamination before insertion. For mixed-vendor environments, validate interoperability and test critical links under expected traffic to ensure stable performance.
