BlueOptics QSFP-AOC-3M-QN-BO InfiniBand/fibre optic cable 3m Male/Male

The BlueOptics QSFP-AOC-3M-QN-BO InfiniBand/fibre optic cable 3m Male/Male is a 3-metre active optical cable designed for high-speed interconnects in data centres and high-performance computing clusters. With QSFP form-factor connectors on both ends, this cable supports short-reach optical links while maintaining signal integrity and low latency. It is intended for environments where reliable, low-power optical connectivity is required for switches, servers and storage systems that accept QSFP interfaces.

Advantages

This active optical cable provides a compact, lightweight alternative to copper while reducing electromagnetic interference and heat generation. The QSFP connectors provide standardized mating for equipment with QSFP ports, ensuring consistent mechanical fit and optical alignment. The 3-metre length offers flexibility for rack-to-rack and intra-rack connections without excess cable slack. As an AOC (Active Optical Cable), it integrates optical transceivers and offers lower power consumption compared with some optical module plus fibre patch solutions.

Suitable for

• High-performance computing clusters and InfiniBand fabrics
• Data centre switch-to-switch, switch-to-server and server-to-storage connections
• Short-reach optical links inside racks and between adjacent racks
• Low-latency networking applications that use QSFP ports

Key specifications

• Cable type: Active Optical Cable (AOC)
• Connector type: QSFP to QSFP, male/male
• Length: 3 metres
• Media: Fibre optic
• Designed for: InfiniBand and high-speed optical interconnects

How to use

Ensure both devices support QSFP AOC connections and are powered down or follow hot-plug guidance from the equipment vendor. Align the QSFP connectors with the device ports and insert firmly until the latch engages. For removal, release the QSFP latch according to the port design and gently withdraw the connector. Route the cable to avoid sharp bends and mechanical stress; maintain the minimum bend radius recommended by the equipment manufacturer. Verify link status on connected devices and consult system logs or diagnostics if link negotiation does not occur.

Recommendations

Store and handle the cable in a clean environment, avoiding contamination of connector endfaces. Do not twist or crease the AOC; use cable management to secure routing and minimize strain. Use this cable for short-reach interconnects where QSFP form-factor compatibility and low-latency optical links are required.
