Network Cable IBM SFP+ 3m SFP+ InfiniBand Fibre Optic Black

The IBM SFP+ 3m InfiniBand/fibre optic cable features SFP+ connectors on both ends and a 3 metre length, providing a direct-attach solution for high-speed links in data centers and networking environments. This black cable is compatible with SFP+ ports and supports InfiniBand standards to deliver low-latency, high-bandwidth connectivity between servers, switches and storage devices.

Advantages

Using SFP+ Direct Attach Cable (DAC) eliminates the need for separate optical transceivers for short runs up to 8.5 metres, simplifying deployment and reducing part count. The cable is MSA-compliant and designed to work with SFP+ ports on IBM BNT switches without requiring port changes, ensuring predictable operation and consistent physical performance. Its fixed 3 m length and SFP+ connectors provide a straightforward, low-latency connection suitable for rack and row-level interconnects.

Suitable for

• Interconnecting servers within the same rack
• Connecting switches and top-of-rack devices
• Linking storage arrays and host adapters supporting InfiniBand or SFP+
• Short-distance high-bandwidth links up to 3 m (DAC use supported up to 8.5 m)

How to use

Insert each SFP+ connector into the corresponding SFP+ port on the devices to be connected until the latch engages. Ensure both ends are seated firmly and verify link status through the devices' management interface. For optimal performance, use this direct attach cable for short-distance connections within racks or between adjacent racks and avoid excessive bending or strain on the cable.

Recommendations

Use the SFP+ DAC for links up to 3 m in typical installations; note that SFP+ DACs are generally supported up to 8.5 m depending on the cable and switch. Confirm MSA compliance and switch compatibility (IBM BNT SFP+ ports) when deploying, and handle connectors carefully to prevent contamination or damage.
