InfiniBand / fibre optic cable HP 487655-B21, 3 m length

HP 487655-B21 is a 3 m InfiniBand / fibre optic cable engineered for high-speed server and storage interconnects. The cable provides an optical link suitable for low-latency, high-bandwidth connections between compatible InfiniBand or optical ports. Designed for data centre and high-performance computing environments, it supports rack-to-rack connections and equipment cabling where a 3-m optical reach is required, offering a straightforward way to extend optical network links without active components.

Advantages

The cable delivers stable optical transmission over a fixed 3 m distance, minimising latency compared with longer or electrically switched connections. Its design is compatible with standard InfiniBand and optical interfaces used in servers, storage arrays and network switches, enabling reliable point-to-point links. Being a passive fibre optic medium, it reduces electromagnetic interference concerns and maintains signal integrity across the connection.

Suitable for

• Interconnecting servers and storage within racks or between adjacent racks
• Low-latency links for high-performance computing clusters
• Optical uplinks between switches and directors in data centre networks
• Replacing or extending existing optical links where a 3 m length is required

Key specifications

• Cable type: InfiniBand / fibre optic
• Length: 3 metres
• Connection: optical plug compatible with InfiniBand/optical ports
• Designed for: server, storage and network interconnects
• Signal characteristics: low-latency, high-bandwidth optical transmission

How to use

Inspect both ends of the cable and the optical ports on connected equipment for dust or debris before installation. Align the optical connectors with the device ports and insert gently until the connector seats securely; avoid excessive force. Route the cable to minimise sharp bends and avoid tight loops to preserve fibre performance. When disconnecting, grasp the connector body rather than pulling on the cable jacket to prevent damage.

Usage recommendations

For reliable operation, use the cable within its specified 3 m length and in environments that protect fibre connectors from contamination. Maintain connector end-face cleanliness with appropriate cleaning tools and store unused ends with protective caps. Ensure compatibility with the optical transceivers or ports in your equipment and verify link settings after installation.
