InfiniBand/optický kábel BlueOptics MCP2M00-A00A-BL 0,5 m SFP28 samec/samec

The BlueOptics MCP2M00-A00A-BL is a 0.5 m InfiniBand / fibre optic direct attach cable with SFP28 male-to-male connectors designed for short-range, high-speed connections in racks and between adjacent racks. It is specified for 25GBase-CR applications and transmits electrical signals over a passive twinax copper assembly with 30 AWG conductor gauge. The cable is MSA-compliant and intended for use where SFP28 ports are available on switches, routers, storage systems and other networking hardware.

Advantages

This 0.5 m SFP28 male/male cable provides low latency and low power consumption typical of passive direct attach twinax assemblies. It supports up to 25 Gbit/s over the 0.5 m length and is manufactured according to MSA standards using high-quality cable and component suppliers to ensure reliable operation and long service life. The compact length and direct SFP28 connectors simplify rack wiring and reduce signal loss compared with longer or adapter-based connections.

Suitable for

• Short-range links inside racks or between adjacent racks
• 25G Ethernet, FCoE and InfiniBand interconnects supporting SFP28
• Connections between switches, routers, storage arrays and servers with SFP28 ports

Key specifications

• Cable type: passive twinax copper (DAC)
• Connector type: SFP28 male to SFP28 male
• Length: 0.5 metres
• Supported data rate: up to 25 Gbit/s
• Conductor gauge: 30 AWG
• Compliance: MSA-compliant
• Typical power consumption: low (passive design)

How to use

Install the BlueOptics SFP28 Direct Attach Cable by inserting each SFP28 connector into the corresponding SFP28 port on the network devices until the latch clicks into place. Ensure both endpoints support passive DAC operation and the same transmission protocol (for example 25GBase-CR). Route the cable within the rack to avoid sharp bends and mechanical strain; avoid kinking or excessive compression of the twinax cable to maintain performance.

Recommendations

For best results, verify device compatibility with passive SFP28 DAC cables and test the link after installation. Keep the cable length appropriate for the intended connection (0.5 m for short, adjacent-rack links) and avoid using passive DACs where only active optical or extended-reach solutions are supported by the hardware.
