SFP+ Direct Attach Cable BlueOptics MCP2103-X01AA 10GBASE-CR 2 m

SFP+ Direct Attach Cable BlueOptics MCP2103-X01AA 10GBASE-CR 2 m is a 2‑metre passive twinax copper cable with integrated SFP+ connectors at both ends, intended for short‑reach 10 Gigabit Ethernet links. The cable supports 10GBASE‑CR signalling and is designed for direct server-to-switch or switch-to-switch interconnects in racks and data center topologies where fixed‑length, low‑latency connections are required.

Advantages

This direct attach cable provides a cost‑effective, low‑power alternative to optical transceivers and separate fiber patch cords for short distances. The integrated SFP+ form‑factor ensures compatibility with equipment that accepts SFP+ modules, while the passive copper construction delivers minimal latency and stable electrical performance. The 2 m length is suitable for common rack and cabinet layouts, reducing the need for additional patching and saving space in dense installations.

Suitable for

• Server-to-switch 10 Gigabit Ethernet connections within the same rack or adjacent racks
• Switch-to-switch links for aggregation and spine-leaf topologies at short range
• High-density network panels where fixed-length, low-latency cabling is preferred
• Temporary or permanent installations that require plug-and-play SFP+ connectivity

Key specifications

• Interface: SFP+ connectors at both ends (10 Gbit/s electrical interface)
• Physical medium: passive twinax copper cable
• Supported standard: 10GBASE‑CR (10 Gigabit Ethernet over copper)
• Cable length: 2 metres
• Latency: very low propagation delay typical for direct-attach copper
• Form factor: SFP+ compatible, hot-pluggable
• Typical use case range: short-reach interconnects within racks or adjacent racks

How to use

Insert each SFP+ connector into the SFP+ port of the respective network devices until the module latches. Ensure the link partners support passive SFP+ direct attach copper cables and that the ports are configured for 10 Gigabit Ethernet operation. No additional transceivers or fiber patch cords are required. Handle the cable by the connector bodies when inserting or removing to avoid stressing the cable assembly, and route the cable to prevent sharp bends that could affect electrical performance.

Usage recommendations

Verify compatibility with your switches and servers before deployment; confirm that device firmware or vendor compatibility lists include support for passive SFP+ direct attach cables. For longer distances or where electrical interference is a concern, consider optical alternatives. Store and install the cable without tight bends and avoid mechanical strain on the connectors to maintain reliable operation.
