SFP+ Direct Attach Cable BlueOptics MCP2103-X003A 10GBASE-CR 3 m

BlueOptics MCP2103-X003A 10GBASE-CR 3 m is a 3-metre SFP+ direct attach twinax copper cable engineered for short-range 10 Gbps links. The cable terminates in SFP+ plugs compatible with SFP+ ports on switches, servers and storage appliances, offering a fixed, low-power alternative to optical transceivers for top-of-rack and adjacent-rack connections. Its direct-attach design reduces component count and latency compared with module-plus-fibre assemblies while maintaining the electrical signalling characteristics required for 10GBASE-CR operation.

Advantages

The direct-attach twinax construction delivers predictable electrical performance and low transmission latency for 10 Gbps links, with reduced power consumption compared with active optical solutions. A 3 m length provides sufficient reach for connections inside racks or between neighbouring racks without the need for separate fibres or transceivers. The integrated SFP+ plugs simplify installation and inventory, eliminating separate module and patch-cable combinations and lowering total cost of ownership for short-distance interconnects.

Suitable for

• Top-of-rack connections between switches and servers
• Server-to-storage links within the same rack or adjacent racks
• High-density switch interconnects in data centre aisles
• Environments where low latency and reduced power draw are required

Key specifications

• Interface: SFP+ to SFP+ direct attach
• Data rate: 10 Gbps (10GBASE-CR)
• Length: 3 metres
• Cable type: Twinax copper with integrated SFP+ connectors
• Application: Short-reach electrical interconnects

How to use

Install the cable by inserting each SFP+ connector into the corresponding SFP+ port on the network devices until the latch engages. Confirm that both ends are seated and that devices detect the 10 Gbps link at the operating system or switch management interface. The cable is plug-and-play for equipment supporting direct-attach SFP+ links; no additional module configuration or fibre management is required. For removal, release the connector latch and pull straight out to avoid damaging the port.

Usage recommendations

Use this direct-attach cable for clean, short-distance 10 Gbps connections inside racks or between adjacent racks. Avoid excessive bending or tension near the connector ends, and maintain proper airflow around equipment to prevent thermal stress. Verify compatibility with your devices' SFP+ ports and link settings before deployment.
