25G SFP28 Cable BlueOptics 25G-SFP28-TWX-P-1M-BL 1m Male/Male

The BlueOptics 25G-SFP28-TWX-P-1M-BL is a 1 meter passive direct attach twinax copper cable with SFP28 connectors on both ends, designed for short-range 25G data links in rack and adjacent-rack installations. It conforms to the 25GBase-CR electrical specification and is intended for use in hardware platforms that accept SFP28 direct attach copper modules. The cable supports low-latency, low-power 25 Gbit/s connections for Ethernet, Fibre Channel over Ethernet (FCoE) and other compatible protocols on short distances.

Advantages

This 1m SFP28 twinax cable provides a cost-effective and energy-efficient alternative to optical transceivers for short-distance links. Passive twinax construction eliminates active electronics in the cable, resulting in very low power consumption and reduced heat generation. The SFP28-to-SFP28 connectivity ensures straightforward plug-and-play integration in compatible switches, routers and storage devices while maintaining MSA-aligned mechanical and electrical characteristics. High-quality components and manufacturing practices increase expected operational lifetime and availability in dense data center deployments.

Suitable for

• Short-range 25G links within racks and between adjacent racks
• High-density data center switch-to-switch and switch-to-server connections
• Storage area network links and converged Ethernet/FCoE connections
• Environments where low latency and low power consumption are required

Key specifications

• Connector type: SFP28 male to SFP28 male
• Length: 1 meter
• Media: passive twinax copper (30 AWG conductors)
• Supported data rate: up to 25 Gbit/s
• Compatible applications: Ethernet, FCoE, Fibre Channel and similar 25G protocols
• Typical use case: direct attach for rack and adjacent rack interconnects

How to use

Insert each SFP28 plug into the SFP28 port of the corresponding network device until the latch engages. Ensure both endpoints support passive 25G twinax direct attach cables and are configured for the intended 25G protocol. Route the cable avoiding excessive bending and mechanical stress; observe standard ESD precautions and connect or disconnect only when devices are powered down if recommended by the equipment vendor. Verify link status in the devices' management interface after installation.

Recommendations

Use this 1m passive SFP28 twinax cable for intra-rack and adjacent-rack 25G connections where short distance, low latency and low power consumption are priorities. Confirm device compatibility with SFP28 passive DACs before deployment and keep cable bends above the minimum bend radius. For longer runs or when optical isolation is required, consider using optical transceivers and fiber instead.
