## Summary description

The BlueOptics SFP-H25G-CU3M is a 3 m InfiniBand/fibre optic cable with SFP28 connectors. It features male/male connectors for reliable data transmission. Ideal for high-speed networking applications.

## Long description

The BlueOptics SFP-H25G-CU3M InfiniBand/fibre optic cable 3 m SFP28 Black is a 3‑metre direct-attach cable with SFP28-compatible male connectors at both ends. Designed for short-reach, high-bandwidth interconnects, this cable supports 25 Gbps class links over copper with a compact SFP28 form factor. Its black outer jacket and fixed length make it suitable for tidy rack and chassis connections in data centre and server environments.
Advantages
This SFP28 cable provides a cost-effective, low-latency physical link for 25 Gbps networking equipment. The male-to-male SFP28 terminations ensure plug-and-play compatibility with devices that accept SFP28 direct-attach copper assemblies. The 3 m length gives moderate reach for cross‑cabinet or within-rack connections while avoiding the added power and complexity of active transceivers. The compact design reduces cable clutter and preserves airflow in dense installations.
Suitable for
 Server-to-switch connections in data centres
 Top-of-rack and end-of-row networking
 High-performance computing and InfiniBand environments requiring SFP28 interfaces
 Short-reach interconnects between storage arrays and host adapters
Key specifications
 Connector type: SFP28 male to SFP28 male
 Length: 3 metres
 Supported data rate: up to 25 Gbps
 Cable medium: direct-attach copper assembly (DAC)
 Jacket colour: black
 Intended reach: short-reach/within-rack and cross‑cabinet links
How to use
Insert each SFP28 connector into the appropriate SFP28 port on your devices until the latch engages. Ensure devices are powered and configured to recognise a direct-attach copper connection at the intended speed (25 Gbps). Route the cable to avoid tight bends and to maintain airflow; secure it lightly to rack rails or cable management points if needed. No additional transceivers or power sources are required for passive assemblies of this type.
Usage recommendations
Verify switch and network adapter compatibility with SFP28 direct-attach copper cables and confirm firmware or driver support for 25 Gbps links. For reliable long-term operation, avoid repeated hot-plug cycles and protect connector ends from dust when not in use.
