BlueOptics QFX-SFP-DAC-5M InfiniBand fibre optic cable SFP+ 5m

The BlueOptics QFX-SFP-DAC-5M InfiniBand fibre optic cable SFP+ 5m is a 5-metre high-speed interconnect designed for short-range, low-latency networking links. It uses SFP+ compatible terminations and is intended for InfiniBand environments where reliable throughput and signal integrity are required. This cable supports high data rates typical of SFP+ interfaces and is suitable for connecting switches, servers and storage devices in dense networking racks.

Advantages

This 5 m fibre optic cable delivers consistent signal quality and reduced latency for InfiniBand links, while its SFP+ terminations ensure compatibility with a wide range of SFP+ ports. The cable’s length is calibrated for common rack and row deployments, minimizing excess slack and supporting neat cable management. Constructed for stable performance in data centre conditions, it offers predictable electrical and optical characteristics to support sustained high-bandwidth traffic.

How to use

Install the BlueOptics SFP+ cable by inserting each SFP+ end into the matching SFP+ ports on the devices to be connected, ensuring the latch engages securely. Route the cable along standard cable management channels to avoid sharp bends and to maintain the recommended bend radius. After connection, verify link status and negotiated speed on both endpoints and confirm that the InfiniBand link is active in the host or switch management interface.

Recommendations

For reliable operation, avoid kinking or tight bends, keep the cable away from high-heat sources, and use appropriate ESD precautions when handling SFP+ connectors. Choose a 5 m length for typical within-rack or short row connections; for longer runs, select a cable length suited to your rack layout and signal requirements.
