Copper Direct Attach Cable BlueOptics H-SFP+CU5M-BL, SFP+ to SFP+, 10GBASE-CR, 5 m, blue

BlueOptics H-SFP+CU5M-BL is a 5-meter copper direct attach cable (DAC) with SFP+ connectors on both ends, designed for 10GBASE-CR links. This fixed assembly provides a low-latency and energy-efficient alternative to optical transceivers for short-reach 10 Gbps connections between network switches, servers and network interface cards. The blue jacket identifies the cable visually in dense cabling environments and the single-piece construction reduces component count and simplifies rack-to-rack or top-of-rack interconnects where compatible SFP+ ports are available.

Advantages

The direct attach design offers predictable electrical performance with minimal latency and lower power consumption compared with active optical modules. Being a passive copper solution, it eliminates the need for separate transceivers and fiber patch cords for many short-distance links, reducing total cost of ownership and simplifying inventory. The 5 m length covers common data center layouts such as top-of-rack to adjacent switches or server pairs while the SFP+ form factor ensures compatibility with equipment that supports standard SFP+ interfaces.

Suitable for

• 10 Gbps short-reach interconnects between switches
• Server-to-switch connections in rack and row deployments
• Direct links between NICs and SFP+ ports
• Top-of-rack and aggregation layer cabling in data centers

Key specifications

• Cable type: copper direct attach cable with integrated SFP+ connectors
• Data rate: 10 Gbps (compatible with 10GBASE-CR)
• Length: 5 meters
• Connector form factor: SFP+ to SFP+
• Jacket color: blue for visual identification
• Typical use: short-reach, point-to-point interconnects

How to use

Insert each SFP+ connector into the corresponding SFP+ port on the networking devices until the connector latches. Ensure that the devices are powered down or that hot-swap procedures recommended by the equipment manufacturer are followed. Verify link status on both devices after connection; the cable requires no configuration beyond standard interface enablement on the switches or servers. Avoid sharp bends and maintain recommended bend radius to preserve signal integrity.

Usage recommendations

For reliable operation, use this 5 m copper direct attach cable within typical data center ambient conditions and keep it away from sources of strong electromagnetic interference. Confirm port compatibility and supported cable types in device documentation before deployment, and route the cable to avoid excessive bending or compression that could affect performance.
