InfiniBand/fibre optic cable BlueOptics SFP-25G-C50CM 0.5 m SFP28 Black

The BlueOptics SFP-25G-C50CM is a 0.5 m fibre optic patch cable with SFP28 connectors designed for short-range high-speed links. Intended for InfiniBand and 25 Gbps Ethernet environments, this black cable offers a compact connection option for switches, routers, NICs and active optical modules that accept SFP28 transceivers. The cable supports reliable data transmission with low latency and is suitable where space and cable management require a short, direct link.

Advantages

The cable provides a standardized SFP28 interface for 25 Gbps links and is manufactured to deliver consistent optical performance over short distances. Its short 0.5 m length minimizes signal loss and clutter in dense rack environments. The black jacket offers a neutral appearance for professional installations, and the pre-terminated assembly reduces installation time compared with field-terminated fibre solutions.

Suitable for

• Short-range 25 Gbps Ethernet connections between switches and servers
• InfiniBand short-reach links in compute clusters
• Patch connections in data centre racks and telecom cabinets
• Direct attach between SFP28-capable transceivers and network ports

Key specifications

• Connector type: SFP28 to SFP28
• Length: 0.5 m
• Supported data rate: 25 Gbps
• Media: fibre optic suitable for short-range high-speed links
• Colour: black jacket
• Suitable for InfiniBand and 25 Gbps Ethernet applications

How to use

Install the cable by gently inserting each SFP28 connector into the corresponding SFP28 port on the networking devices until the latch engages. Ensure ports on both ends are compatible with SFP28 transceivers and that devices are powered down or follow hot-plugging procedures recommended by the equipment manufacturer. Route the cable to avoid sharp bends and mechanical stress; the short length is optimized for direct patching inside racks or between adjacent devices.

Recommendations

Verify transceiver and port compatibility before use and confirm firmware or driver support for 25 Gbps operation on connected devices. Avoid tight bends and excessive pulling force on the cable. For data centre installations, label both ends to simplify maintenance and ensure the cable is used within its intended short-reach range.
