BlueOptics CBL-10GSFP-DAC-2M-BL InfiniBand/fibre optic cable SFP+ SFP+ DAC 2m Male/Male

The BlueOptics CBL-10GSFP-DAC-2M-BL is a 2-meter direct-attach cable with SFP+ connectors on both ends, engineered for short-reach, high-speed links in server rooms, switch stacks and storage arrays. It supports InfiniBand and SFP+ fibre optic applications to deliver low-latency, high-throughput connectivity where reliable point-to-point links are required. The compact cable and fixed connectors help reduce rack-space clutter and simplify connections between compatible network devices.

Advantages

This SFP+ DAC cable provides a straightforward, cost-effective solution for 10 Gbps links without the need for separate transceivers. The pre-terminated male-to-male configuration ensures plug-and-play installation, consistent signal integrity and minimal power consumption compared with active optical modules. With a 2 m length, the cable balances flexibility and neat cable management for typical data-center and telecom rack layouts.

Suitable for

• Direct connections between switches, routers and servers using SFP+ ports
• Short-reach InfiniBand links in compute clusters
• Storage area network (SAN) connections and top-of-rack uplinks
• Network test benches and temporary interconnects in labs

Key specifications

• Length: 2 metres
• Connector type: SFP+ male to SFP+ male
• Supported interface: InfiniBand and SFP+ fibre optic applications
• Data rate: designed for 10 Gbps class links
• Cable type: direct-attach copper assembly (DAC)

How to use

Ensure both devices support SFP+ DAC connections and are powered off or in maintenance mode if required by your hardware procedures. Insert each SFP+ connector into the appropriate port until it latches, then verify link status through device LEDs or management interfaces. For best results, avoid sharp bends in the cable and maintain the specified 2 m routing to prevent strain on connectors.

Recommendations

Use the cable in rack environments with compatible SFP+ ports and avoid exposure to liquids, extreme temperatures or mechanical stress. For longer runs or environments requiring electrical isolation, consider active optical cables or transceiver-plus-fibre solutions.
