SFP+ Direct Attach kabel CBO 2127934-1-BL 0,5 m samec–samec 10 Gbit/s

The CBO SFP+ direct attach cable 0.5 m Male–Male 10 Gbit/s is a 0.5 metre twinax copper cable with SFP+ male connectors on both ends, designed for short-range high-speed links. It enables 10 Gbit/s connections between network devices such as switches, servers and network adapters. The compact, low-profile design reduces port congestion in rack environments and provides low latency, making it suitable for data centre and top-of-rack interconnects.

Advantages

This SFP+ direct attach cable delivers a cost-effective, power-efficient alternative to optical transceivers for short distances, eliminating the need for separate transceivers and LC patch cables. Its fixed 0.5 m length simplifies cable management in dense racks while maintaining consistent 10 Gbit/s performance. The twinax copper construction offers reliable signal integrity with reduced latency compared with longer copper or optical assemblies for equivalent short-range links.

Suitable for

• Top-of-rack connections between switches and servers
• Direct links between network adapters and storage devices
• Short intra-rack interconnects in data centres
• High-density patching where space and port count are constrained

Key specifications

• Cable type: twinax copper direct attach
• Connector type: SFP+ male to SFP+ male
• Maximum data rate: 10 Gbit/s
• Length: 0.5 m
• Latency: low, suitable for short-range high-speed links
• Form factor: low-profile SFP+ compatible

How to use

Insert each SFP+ connector into the appropriate SFP+ port on the network devices until it latches securely. Ensure both devices are powered and configured for 10 Gbit/s operation. For best results, avoid sharp bends and keep the cable run within the specified 0.5 m length. Verify link status on the devices and confirm negotiated speed and duplex through the network interface management tools.

Recommendations

Use this 0.5 m SFP+ direct attach cable for short-distance connections inside racks or between adjacent rack units. Keep the cable free from excessive mechanical stress and routing through high-interference power bundles. For links beyond short rack-level distances, consider active optical solutions or longer-range copper options.
