## Summary description

The BlueOptics 25G-SFP28-TWX-P-0501-BL is a 5 m InfiniBand/fibre optic cable featuring Male/Male SFP28 connectors. It is designed for high-speed data transmission, ensuring reliable connectivity for data centers and networking applications. This cable supports 25G data rates, making it ideal for modern networking needs.

## Long description

The BlueOptics 25G-SFP28-TWX-P-0501-BL is a 5 m InfiniBand/fibre optic direct-attach twinax cable with Male-to-Male SFP28 connectors, designed for short-reach, high-speed 25G links in racks and between adjacent racks. The cable implements a passive 25GBase-CR twinax copper design (30 AWG) that follows MSA guidelines and is compatible with equipment that supports SFP28 25G direct attach connections. It supports Ethernet, FCoE, Fibre Channel and InfiniBand traffic up to 25 Gbit/s over a 5 m distance and is intended for use in switches, routers, storage arrays and other network hardware that accepts SFP28 passive DACs.
Advantages
The cable provides a low-latency, low-power (passive) connection for high-density rack environments and short-distance interconnects. Construction uses MSA-compliant SFP28 interfaces and 30 AWG twinax conductors to maintain signal integrity at 25G rates while keeping power consumption and heat generation minimal. The product is manufactured from selected components from established telecom suppliers to achieve consistent performance and extended service life suitable for continuous operation.
Suitable for
Short-reach server-to-switch and switch-to-switch links inside racks or between adjacent racks
High-density data center top-of-rack or leaf-spine deployments
Storage and SAN connections using Fibre Channel or FCoE at 25G
InfiniBand and other 25G networking applications that accept passive SFP28 DACs
Key specifications
Length: 5 meters
Data rate: up to 25 Gbit/s
Connector type: SFP28 male to SFP28 male (MSA-compliant)
Cable type: Passive twinax copper (25GBase-CR), 30 AWG
Typical use: short-distance direct-attach connections in racks
Supported protocols: Ethernet, FCoE, Fibre Channel, InfiniBand
How to use
Insert each SFP28 plug fully into the appropriate SFP28 port on the networking devices until the latch engages. Ensure both connected devices officially support passive 25GBase-CR SFP28 direct-attach cables. After insertion, verify link status and negotiate link speed on the devices; no external power or transceivers are required for passive operation. For best results, route the cable to avoid sharp bends and mechanical strain on the connectors.
Usage recommendations
Use this passive 25G SFP28 twinax cable for short, fixed connections within racks or between adjacent racks where 5 m length is appropriate. Confirm device compatibility with passive DACs and the required protocols before deployment. Avoid repeated hot-plugging and maintain bend radius to preserve cable integrity and signal performance.
