Product information

Description

The Cisco SFP-H25G-CU4M SFP28 InfiniBand 4m is a direct-attach cable designed for short-reach, high-density networking applications. With SFP28 connectors on both ends and a 4-meter length, this cable supports reliable high-speed data transfer in server racks, switches and other data centre equipment. Its compact twin-colour black and grey jacket provides robust mechanical protection while remaining flexible for neat cable management.

Advantages

This SFP28 InfiniBand cable delivers low latency and consistent signal integrity suitable for 25 Gbps interconnects and compatible environments. The direct-attach design eliminates the need for transceivers, reducing power consumption and simplifying installations. The 4 m length offers extended reach within rack rows or between adjacent racks, while the rugged construction resists wear and supports repeated insertion and removal.

Suitable for

  • High-performance computing clusters and InfiniBand fabrics
  • Server-to-switch and switch-to-switch connections in data centres
  • Top-of-rack and end-of-row cabling where 4 m reach is required
  • Environments requiring consistent low-latency 25 Gbps links

Key specifications

  • Cable type: Direct-attach copper with SFP28 connectors on both ends
  • Supported link speed: Designed for 25 Gbps class connections
  • Length: 4 m
  • Connector type: SFP28 to SFP28
  • Jacket colour: Black and grey

How to use

Ensure both network devices support SFP28 direct-attach copper connections and are powered down or follow hot-swap guidelines from the equipment vendor. Align the SFP28 connector latch with the port and insert the plug until it clicks into place. Verify link activity and negotiated speed through device management interfaces or LEDs. When removing the cable, depress the connector latch and pull straight out to avoid damaging the port.

Usage recommendations

For optimal performance, route the cable to avoid sharp bends and mechanical strain; maintain the minimum bend radius specified by your equipment vendor. Use this cable within short-reach applications up to 4 m and choose shorter lengths when possible to reduce clutter and improve airflow in dense racks.
