SFP+ copper twinax cable CBO SFP-H10GB-CU1-5M-BL 2 m, male-to-male, 10 Gbit/s

The BlueOptics SFP+ copper twinax cable SFP-H10GB-CU1-5M-BL is a 2 m male-to-male direct-attach cable engineered for 10 Gbit/s short-reach links. It combines SFP+ form-factor connectors with a passive twinax copper cable to deliver low-latency, high-throughput connectivity between switches, servers and network interface cards. The design targets rack-level interconnects and top-of-rack deployments where cost-effective, power-efficient cabling is required.

Advantages

The passive twinax construction offers low power consumption compared with active optical modules and reduces heat generation in dense racks. With integrated SFP+ connectors on both ends, the cable provides a compact, plug-and-play solution that simplifies cabling and eliminates the need for separate transceivers and fiber patch cords. Its 2 m length is optimized for short-reach connections inside cabinets or between adjacent racks while maintaining signal integrity for 10 Gbit/s traffic.

Suitable for

• Short-reach 10 Gbit/s links between switches and routers
• Direct connections from servers to top-of-rack switches
• Interconnects for network interface cards (NICs) and storage controllers
• High-density rack deployments and data center topologies

Key specifications

• Connector type: SFP+ male-to-male
• Cable type: Passive twinax copper
• Data rate: 10 Gbit/s
• Length: 2 metres
• Use case: Short-reach, direct-attach cabling
• Latency: Low (passive copper path)

How to use

Insert each SFP+ connector into the SFP+ port of the devices to be linked, ensuring the latch engages and the connector is fully seated. No external power or transceiver modules are required for passive twinax operation. Verify link status LEDs on the connected devices and confirm network settings such as speed and duplex if necessary. For hot-pluggable systems, follow host equipment guidelines for safe insertion and removal to avoid port damage.

Recommendations

Choose this 2 m passive SFP+ twinax cable for rack-level connections where short reach and low power consumption are priorities. Avoid excessive bending near the connector ends, keep the cable within recommended bend radii, and route it to minimize mechanical stress and interference. Confirm compatibility with your switch or server vendor and follow their supported cable lists for guaranteed operation.
