Direct Attach Cable (DAC) CBO NEX-5020-TX5M 5 m SFP+ passive copper cable

CBO NEX-5020-TX5M is a 5-metre SFP+ Direct Attach Cable (DAC) intended for short-range 10 Gbps interconnects between network devices with SFP+ ports. As a passive copper twinax assembly, the cable provides a low-latency electrical link optimized for rack-to-rack and within-rack connections. The integrated SFP+ form-factor plugs at each end eliminate the need for separate transceivers, reducing hardware costs and simplifying installation in data center and server-room environments.

Advantages

The passive SFP+ DAC construction delivers reduced power consumption compared with optical transceivers, while maintaining 10 Gbps data throughput and low latency suitable for high-performance switching and server applications. Its fixed 5 m length enables predictable signal characteristics and straightforward cable management in dense rack deployments. The pre-terminated twinax cable and standardized SFP+ connectors provide plug-and-play compatibility with devices that support SFP+ passive copper links.

Key specifications

How to use

Insert each SFP+ connector into the corresponding SFP+ port on the network devices until the retention latch engages. Ensure both devices are powered and configured to accept passive SFP+ links. Verify link negotiation and network settings on connected devices. Route the 5 m cable to avoid sharp bends and physical strain; secure with cable ties or management panels if required. For maintenance, unplug by depressing the latch and pulling the SFP+ housing straight out to prevent connector damage.

Recommendations

Use the DAC for short, high-bandwidth links inside racks or between adjacent racks. Avoid extended runs beyond the recommended distance for passive SFP+ copper assemblies and do not exceed the cable's bend radius. Confirm device compatibility with passive SFP+ modules and consult switch or server documentation if link negotiation issues occur.
