InfiniBand/fibre optic cable BlueOptics 25G-SFP28-TWX-P-5M-BL 5m Male/Male

The BlueOptics 25G-SFP28-TWX-P-5M-BL is a 5-meter InfiniBand / fibre optic cable with SFP28 male-to-male connectors designed for high-speed direct-attach connections in rack and adjacent-rack environments. The cable supports 25G data rates and is compatible with hardware platforms that accept SFP28 25GBase-CR direct-attach connections. It is intended for short-distance, high-performance links between switches, routers, storage systems and other networking equipment.

Advantages

This 5 m SFP28 cable offers a passive twinax direct-attach solution optimized for short-reach connections, delivering low latency and low power consumption. Manufactured to MSA-aligned mechanical and electrical specifications, the cable uses high-quality components to ensure reliable signal integrity and long service life. The male-to-male SFP28 connectors provide a plug-and-play experience in systems that support passive DACs and 25GBase-CR interfaces.

Suitable for

• Connecting switches and routers within server racks or across adjacent racks
• High-performance computing and data center uplinks at 25G
• Storage system interconnects and short-distance InfiniBand or Fibre Channel links

Key specifications

• Length: 5 meters
• Connector type: SFP28 male to SFP28 male
• Supported data rate: up to 25 Gbps
• Transmission medium: passive twinax / direct attach copper for short distances
• Wire gauge: 30 AWG
• MSA-compliant SFP28 interface

How to use

Insert each SFP28 plug into the SFP28 port of the corresponding network device until the latch secures. Ensure both devices support passive 25GBase-CR direct attach twinax cables and that link settings (speed/duplex where applicable) match on both ends. Route the cable within the rack to avoid sharp bends and maintain minimum bend radius. For initial deployment, verify link status and run diagnostics to confirm 25G connectivity.

Recommendations

Use this cable for short-reach, high-bandwidth interconnects inside racks or between adjacent racks. Avoid exceeding the recommended bend radius, prevent sustained mechanical stress on connector ends, and confirm hardware compatibility with passive DACs before installation. For mixed-vendor environments, test a sample link to verify full functionality with your specific devices.
