SFP+ Cable CBO 3 m Male/Male 10 Gbit/s, model 2127931-4-BL

The SFP+ Cable CBO 3 m Male/Male 10 Gbit/s, model 2127931-4-BL is a direct-attach copper cable designed for short-range, high-speed connections between SFP+ ports. With a fixed 3 m length and male-to-male connectors, this assembly provides up to 10 Gbit/s throughput and low latency for links between switches, servers and storage devices. The cable is intended for reliable rack-level interconnects and data center patching where a pre-terminated, robust solution is required.

Advantages

This SFP+ direct-attach cable offers straightforward plug-and-play installation, low power consumption compared with optical transceivers, and predictable performance over its fixed length. The male-to-male configuration reduces the need for additional transceivers and simplifies link provisioning. Its construction supports stable signal transmission for short-range 10 Gbit/s connections and minimises insertion points and potential signal loss.

Suitable for

• Uplinks between access and aggregation switches in racks
• Server-to-switch connections within the same rack or adjacent racks
• Storage array interconnects and SAN patching at 10 Gbit/s
• Short-range data centre patch panels and top-of-rack deployments

Key specifications

• Connector type: SFP+ male to SFP+ male
• Nominal length: 3 metres
• Maximum supported data rate: 10 Gbit/s
• Cable type: Direct-attach copper assembly
• Typical latency: low, suitable for short-range links
• Application: short-range interconnects in racks and data centres

How to use

Insert each SFP+ connector into the corresponding SFP+ port on the network devices until the latch engages. Verify link status on both devices and configure network settings as required by your environment. Use the fixed 3 m length to plan rack layouts and avoid excessive cable slack; route the cable to minimise sharp bends and mechanical strain. For removal, depress the connector latch and pull straight out to avoid damage to the port or cable.

Recommendations

Use this direct-attach SFP+ cable for reliable, short-distance 10 Gbit/s links inside racks or between adjacent racks. Ensure that connected devices support passive SFP+ copper assemblies and that port firmware is compatible. Maintain gentle bend radii and secure the cable to avoid strain and maintain consistent signal performance.
