BlueOptics QSFP-AOC-3M-IB-BO InfiniBand Fibre Optic Cable 3m Male/Male

The BlueOptics QSFP-AOC-3M-IB-BO InfiniBand Fibre Optic Cable 3m Male/Male is a 3-metre active optical cable with QSFP form-factor connectors designed for high-speed InfiniBand links. It provides a direct optical connection between QSFP ports and is intended for short-reach, high-bandwidth interconnects in data centre and high-performance computing environments. The cable combines compact QSFP connectivity with the benefits of optical transmission to reduce electromagnetic interference and enable sustained throughput for demanding workloads.

Advantages

This active optical cable offers low latency and high bandwidth suitable for InfiniBand fabrics, with male QSFP connectors on both ends for straightforward plug-and-play installation. Being optical, it reduces signal loss over short distances compared with copper alternatives and avoids ground loop issues. The 3 metre length provides flexibility in rack and shelf arrangements while maintaining signal integrity and consistent performance for clustered systems and storage fabrics.

Suitable for

• Interconnecting switches, routers and host adapters with QSFP ports in data centres
• High-performance computing clusters and server-to-server links
• Storage area networks and high-throughput storage arrays
• Low-latency trading systems and latency-sensitive applications

Key specifications

• Connector type: QSFP male to QSFP male
• Length: 3 metres
• Transmission medium: active optical cable (AOC)
• Protocol compatibility: InfiniBand
• Use case: short-reach, high-bandwidth interconnects
• Benefits: reduced electromagnetic interference, low latency optical transmission

How to use

Install the cable by inserting each QSFP male connector into compatible QSFP ports on network switches, host channel adapters or servers. Ensure ports are powered down or follow hot-plug procedures recommended by your hardware vendor if connecting under load. Verify link status via device LEDs or management software and confirm negotiated link speed and lane configuration. Avoid tight bends and secure the cable to prevent strain at connector ends.

Recommendations

For optimal performance, route the cable with gentle bends, keep it clear of sources of mechanical stress, and follow ambient temperature guidelines of connected equipment. Use this 3 m AOC for intra-rack or adjacent-rack connections where InfiniBand performance and low latency are required. When replacing or extending links, match protocol and speed capabilities of both endpoints to ensure compatibility.
