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

The BlueOptics QSFP-AOC-3M-SP-BO InfiniBand fibre optic cable 3m Male/Male is a 3-metre active optical cable with QSFP connectors designed for high-speed data transmission in data centre and networking environments. This InfiniBand-compatible cable provides a compact, low-latency connection between QSFP ports and is intended for short to medium reach interconnects where reliable signal integrity and reduced electromagnetic interference are required.

Advantages

The cable combines the bandwidth capability of QSFP interfaces with the flexibility of an active optical cable, offering stable throughput and low power consumption compared with equivalent copper assemblies. Its male-to-male QSFP terminations allow straightforward plug-and-play deployment in compatible switches, servers and storage systems. Being an optical link, it eliminates susceptibility to electrical interference and enables denser rack layouts due to thinner and lighter cabling.

Suitable for

• High-performance computing clusters using InfiniBand interconnects
• Top-of-rack and spine switch connections in data centres
• Direct server-to-switch or switch-to-switch links requiring QSFP ports
• Environments where reduced electromagnetic interference and longer reach than copper are needed

Key specifications

• Connector type: QSFP male to QSFP male
• Length: 3 metres
• Media: active optical cable (AOC)
• Protocol compatibility: InfiniBand
• Form factor: QSFP footprint for 4-lane high-speed links
• Typical use: short- to medium-range high-bandwidth interconnects

How to use

Insert each QSFP connector into the corresponding QSFP port on network equipment until the latch engages, ensuring the orientation matches the port keying. No additional configuration is required on devices that support QSFP AOCs; the cable is detected as a standard InfiniBand optical link. For removal, depress the connector latch and pull the connector straight out to avoid damaging the port. Route the cable to avoid sharp bends and maintain the recommended minimum bend radius for optical assemblies.

Recommendations

Install the cable in powered-down or low-activity conditions when possible, verify port compatibility before connecting, and avoid kinking or excessive twisting. Keep the connectors capped when not in use and follow standard electrostatic discharge (ESD) precautions. For reliable performance, use this cable within typical data centre temperature and humidity ranges and ensure devices support the InfiniBand speeds intended for your deployment.
