## Summary description

The BlueOptics SFP-H25G-CU5M-BL is a 5 m InfiniBand fibre optic cable with SFP28 connectors. It features male/male connectors for reliable data transmission and is designed for high-speed networking applications.

## Long description

The BlueOptics SFP-H25G-CU5M-BL InfiniBand fibre optic cable is a 5 m direct attach solution with SFP28-to-SFP28 connectors in a black jacket. Designed for short-distance, high-speed connections in racks and between adjacent racks, this cable supports 25G data rates and is intended for use with hardware platforms that accept SFP28 direct attach twinax copper cables. The cable is supplied with male/male SFP28 connectors and a compact construction suitable for dense rack environments.
Advantages
This SFP28 direct attach cable provides a fixed 5 m channel for reliable electrical signal transfer at up to 25 Gbps and low latency. As a passive twinax solution, it has low power consumption compared with active optical transceivers and simplified installation with plug-and-play connectivity. The cable uses a robust black jacket and follows MSA-compliant SFP28 form-factor conventions for broad compatibility with switches, routers and storage systems that support 25G Direct Attach Cables.
Suitable for
High-density rack-to-rack connections in data centres
Server-to-switch and switch-to-switch links within the same rack or adjacent racks
25G Ethernet, FCoE and InfiniBand short-reach interconnects
Key specifications
Connector type: SFP28 male to SFP28 male
Length: 5 m
Data rate: up to 25 Gbps
Cable type: passive twinax copper (Direct Attach Cable)
Wire gauge: 30 AWG
Colour: black
Weight: 0.13 kg
How to use
Ensure connected devices support passive SFP28 Direct Attach Cables and the 25GBase-CR electrical interface. With both devices powered according to their vendor instructions, insert each SFP28 connector into the appropriate SFP28 port until the latch engages. Route the cable to avoid sharp bends and mechanical strain; the 5 m length is intended for short-reach interconnects inside and between adjacent racks. If interoperability checks are required, verify link negotiation and speed in the network device management interface after insertion.
Usage recommendations
Use this cable for short-distance, high-bandwidth links where low latency and low power consumption are priorities. Keep the cable within its intended 5 m range, avoid excessive bending or compression near the connector boots, and confirm that your equipment vendor supports passive SFP28 DACs to ensure proper operation.
