Cabo DAC CBO BN-SP-CBL-3M 3 m SFP+ Direct Attach Copper

Direct Attach Copper (DAC) cable CBO BN-SP-CBL-3M is a 3 meter SFP+ twinax copper cable designed for short-reach 10Gbps links between SFP+ ports. Intended for direct attachment between network switches, servers and network interface cards, this cable removes the need for separate optical transceivers and combines electrical integrity with low latency for rack-level interconnects in data center environments.

Advantages

This SFP+ direct attach copper cable offers a simple, cost-efficient solution for 10Gbps connections over short distances. Its integrated twinax construction reduces component count and power consumption compared with fiber-plus-transceiver assemblies, while providing consistent electrical performance and low signal latency. The fixed 3 m length optimizes rack-to-rack and top-of-rack cabling runs, maintaining signal reliability without active components.

Key specifications

How to use

Insert the SFP+ plug ends into the corresponding SFP+ ports on network switches, servers or NICs until the retention latch engages. Ensure both devices support direct-attach SFP+ copper cables and that port configurations match the intended 10Gbps operation. Route the cable to avoid excessive bending or mechanical stress and maintain the specified 3 m distance between endpoints for optimal signal performance.

Recommendations

For reliable operation, verify compatibility with your switch or server vendor’s SFP+ copper policy and confirm firmware or port settings support passive DAC cables. Avoid sharp bends, heavy compression, or exposure to temperatures outside the device specifications. Use this cable for short, fixed-length connections inside racks or between adjacent racks to minimize latency and power draw compared with optical transceiver solutions.
