Copper SFP+ Direct Attach Cable BlueOptics 74752-1308 10GBASE-CR 3 m

BlueOptics Copper SFP+ Direct Attach Cable 3 m is a Twinax copper cable engineered for SFP+ ports and designed to support 10GBASE-CR short-reach 10 Gigabit Ethernet links. The 3‑meter fixed-length assembly provides a direct-attach connection between switches, servers or storage systems without active optical transceivers, yielding a low-latency, energy-efficient link suitable for data center top-of-rack and intra-rack interconnects.

Advantages

The copper SFP+ direct attach cable offers lower latency and reduced power consumption compared with active optical solutions, while delivering reliable 10 Gbps throughput for short-distance links. Its integrated SFP+ cages simplify installation and reduce component count, and the 3 m length balances reach and cable management for dense rack deployments. The cable is factory-terminated to ensure consistent signal integrity and simplified replacement.

Suitable for

• Top-of-rack and intra-rack switch-to-switch connections
• Server-to-switch or storage-to-switch links in data centers
• Short-distance 10 Gigabit Ethernet aggregation and access layers
• Environments where low latency and low power are required

Key specifications

• Connector type: SFP+ twinax direct-attach (fixed assembly)
• Cable medium: copper twinax
• Supported standard: 10GBASE-CR for 10 Gbps Ethernet
• Length: 3 meters
• Primary use: short-range, direct-attach interconnects
• Typical characteristics: low latency, low power consumption

How to use

Insert each SFP+ module end into the corresponding SFP+ port on the network devices until the latch clicks to secure the connection. Ensure devices are powered and configured for 10 Gbps operation and verify link status in the network equipment management interface. Route the cable to avoid sharp bends and maintain recommended bend radius for twinax copper assemblies. For replacement, power down or logically disable interfaces if required by your equipment and remove the cable by depressing the release latch.

Usage recommendations

Use this 3 m copper SFP+ direct attach cable for short-distance, high-performance links inside racks and between adjacent racks. Avoid running the cable near high-interference power sources, observe the manufacturer's recommended bend radius, and verify compatibility with your SFP+ ports and switch firmware for optimal operation.
