25G SFP28 optický kábel BlueOptics 25G-SFP28-TWX-P-3M-BL 3 m konektor samec/konektor samec

The BlueOptics 25G-SFP28-TWX-P-3M-BL is a 3 metre Direct Attach Cable (DAC) with SFP28 connectors on both ends, designed for short-reach, high-speed interconnects in racks and adjacent-rack environments. This passive twinax copper cable supports 25GBase-CR transmission and is intended for linking switches, routers, storage systems and other network hardware that accept SFP28 to SFP28 direct attach connections. The cable is manufactured to MSA-compliant specifications and is suitable for Ethernet, FCoE and Fibre Channel applications at up to 25 Gbit/s over a 3 m distance.

Advantages

The cable provides a low-latency, low-power connection with passive design requiring no external power. Its twinax copper construction ensures stable electrical signal transfer for short distances while keeping power consumption minimal. Built with industry-grade components and tested for compatibility, this 3 m SFP28 DAC offers predictable performance, reduced failure rates and a long operational lifetime suitable for dense data centre cabling.

Suitable for

• Interconnects between switches and routers in server racks
• Short-distance links between adjacent racks
• Connections to storage systems and SAN equipment supporting 25G
• Environments using Ethernet, FCoE or Fibre Channel at 25 Gbit/s

Key specifications

• Length: 3 metres
• Connector type: SFP28 to SFP28 (male/male)
• Data rate: up to 25 Gbit/s
• Medium: passive twinax copper (direct attach)
• AWG: 30
• Compliance: MSA-compliant electrical interface

How to use

Install the cable by plugging each SFP28 connector into the corresponding SFP28 port on the network devices while both devices are powered according to the vendor guidelines. Ensure the device firmware and driver configurations support passive 25G DAC connections. For reliable operation, route the cable to avoid sharp bends and mechanical stress, and verify link status and speed in the device management interface after connection.

Recommendations

Use this passive 3 m SFP28 DAC for short interconnects inside racks or between adjacent racks where low latency and low power consumption are required. Confirm hardware compatibility with your equipment vendor and keep firmware up to date to ensure full functionality.
