## Summary description

The BlueOptics 25G-SFP28-TWX-P-50CM-BL is a 0.5 m InfiniBand/fibre optic cable designed for high-speed data transmission. It features SFP28 connectors on both ends, ensuring compatibility and reliable performance. This cable is ideal for connecting network devices in data centers and enterprise environments, providing efficient data transfer rates of up to 25 Gbps.

## Long description

The BlueOptics 25G-SFP28-TWX-P-50CM-BL is a 0.5 m InfiniBand / fibre optic direct attach cable with SFP28 male connectors on both ends. It is designed for short-reach high-speed links in racks and adjacent rack rows, providing data transfer rates up to 25 Gbps. The cable implements a passive twinax copper design compatible with 25GBase-CR and is intended for use in switches, routers, storage systems and other hardware that support SFP28 direct-attach connections.
Advantages
This 0.5 m SFP28 to SFP28 cable offers low latency and low power consumption typical of passive direct attach twinax solutions. It is manufactured to MSA-compliant mechanical specifications and uses high-quality components that increase reliability and service life. The short length simplifies rack-level connectivity, reduces signal attenuation over short distances and provides a cost-effective alternative to active optical transceivers for compatible hardware platforms.
Suitable for
Short-distance rack-to-rack or intra-rack 25 Gbps links
Connecting SFP28 ports on switches, routers and storage systems
InfiniBand and Ethernet / FCoE / Fibre Channel applications up to 25 Gbps
Data center top-of-rack and adjacent-rack interconnects
Key specifications
Cable type: passive twinax (direct attach) with twinax copper conductors
Connector type: SFP28 male — SFP28 male
Nominal data rate: up to 25 Gbps
Length: 0.5 metres
Wire gauge: 30 AWG
Standard compliance: 25GBase-CR and SFP28 MSA mechanical compatibility
Typical power consumption: very low (passive cable, no active electronics)
How to use
Install the cable by inserting one SFP28 connector into the SFP28 port of the first device and the other connector into the corresponding SFP28 port of the second device. Ensure both devices support passive 25GBase-CR direct attach twinax cables and that firmware or software settings do not restrict the use of third-party DACs. Route the cable to avoid sharp bends and mechanical stress; maintain bend radius recommendations for twinax cables. No external power or configuration is required for the cable itself.
Usage recommendations
For reliable operation, use the cable for short-reach links within racks or between adjacent racks and verify device compatibility with passive SFP28 DACs. Avoid excessive bending and tension, keep connections clean and periodically inspect connectors for damage to maintain signal integrity and long-term availability.
