SFP+ Cable CBO 45W3039-BL 5 m Male/Male 10 Gbit/s

SFP+ Cable CBO 45W3039-BL 5 m Male/Male 10 Gbit/s is a 5-metre twinax copper direct-attach cable with SFP+ male connectors at both ends. It supports 10 Gbit/s data rates for short-reach, high-throughput links between switches, servers and network interface cards. The cable is designed to deliver low latency and power-efficient connectivity in data centre and enterprise LAN environments where reliable, point-to-point connections are required.

Advantages

The cable offers a compact, single-unit direct-attach solution that eliminates the need for separate transceivers and fibre cabling for short links. Its copper twinax design provides low power consumption and predictable performance at 10 Gbit/s, while SFP+ form-factor compatibility ensures plug-and-play operation with SFP+ ports. The 5 m length covers common rack-to-rack and within-rack connections without excess slack.

Suitable for

• Short-reach connections between switches and servers within racks or across adjacent racks
• Direct links between network interface cards (NICs) and switches
• Top-of-rack and edge switch interconnects in data centres
• Environments where low latency and reduced power consumption are required

Key specifications

• Connector type: SFP+ male to SFP+ male
• Cable type: Twinax copper direct-attach
• Length: 5 metres
• Maximum data rate: 10 Gbit/s
• Typical use: Short-reach, point-to-point connections
• Form factor: SFP+ compatible

How to use

Insert each SFP+ connector into the SFP+ port of the devices to be connected, ensuring the latches engage and the connectors seat fully. No additional transceivers or configuration changes are normally required on devices that support SFP+ direct-attach cables. Verify link status and negotiate speed on the connected network devices; if link does not establish, check port compatibility, firm ware settings and physical seating of the connectors.

Usage recommendations

For reliable operation, use the cable within its specified 5 m range and avoid tight bends or excessive mechanical stress. Install in a way that minimises strain on the connector ends and maintain proper airflow in rack environments. Confirm device compatibility with SFP+ direct-attach twinax cables and, where applicable, update device firmware to the latest stable release.
