InfiniBand/fibre optic cable SFP+ BlueOptics CAB-SFP-SFP-3M-BL 3m Male/Male

The BlueOptics CAB-SFP-SFP-3M-BL is a 3-meter SFP+ direct attach cable designed for short-reach high-speed links in racks and adjacent rack rows. It uses SFP+ connectors on both ends (male-to-male) and supports InfiniBand, Ethernet, FCoE and Fibre Channel transmissions up to 10 Gbit/s over a 3 m distance. The cable is built to MSA-compliant SFP+ DAC specifications and is intended for reliable connectivity between switches, routers, servers and storage systems that accept SFP+ passive twinax connections.

Advantages

The cable provides a low-latency, low-power passive twinax solution for short-distance interconnects. Constructed from quality components and conforming to MSA SFP+ standards, it offers plug-and-play compatibility with hardware platforms that support SFP+ passive DACs. Its passive design eliminates active electronics in the cable body, reducing power consumption and potential points of failure while delivering consistent 10 Gbit/s performance across the specified distance.

Key specifications

How to use

Install the cable by inserting each SFP+ connector into the corresponding SFP+ port on your networking devices until the latch engages. Verify that both devices support passive SFP+ DACs and the chosen protocol (Ethernet, Fibre Channel, InfiniBand or FCoE). After physical connection, check device link indicators and the host system to confirm negotiated 10 Gbit/s operation. For safe handling, avoid sharp bends, kinks and excessive pulling force on the cable; route the cable to prevent mechanical stress.

Recommendations

Use this 3 m SFP+ passive twinax cable for short-distance, high-throughput links inside racks or between adjacent racks. Confirm hardware compatibility with passive DACs and retain manufacturer guidance for insertion and removal. For longer distances or environments requiring optical isolation, select an active or fiber-based SFP+ solution instead.
