InfiniBand/kuituoptinen kaapeli SFP+ BlueOptics CBL-10GSFP-DAC-3M-BL 3 m uros/uros

The BlueOptics CBL-10GSFP-DAC-3M-BL is a 3 m direct-attach SFP+ cable designed for short-reach, high-speed connections in racks and adjacent rack environments. This BlueOptics passive twinax copper cable has SFP+ male connectors on both ends and complies with SFP+ MSA electrical and mechanical specifications, enabling 10GBase-CR-class links for Ethernet, FCoE, Fibre Channel and InfiniBand applications up to 10 Gbit/s over a 3 meter distance.

Advantages

The cable offers low latency and very low power consumption compared with active optical modules, and its passive twinax design removes the need for additional active circuitry in the cable itself. Manufactured from quality components and tested for compatibility with major networking platforms, this SFP+ direct attach cable provides predictable performance and a long service life suitable for data center use. The integrated SFP+ terminations simplify installation and reduce potential points of failure compared with separate transceivers and patch cords.

Key specifications

How to use

Insert each SFP+ connector into the corresponding SFP+ port of the devices to be linked, ensuring the latch engages and the connectors are fully seated. Use the 3 m length to route the cable through racks or between adjacent racks without excessive bending; maintain the manufacturer’s minimum bend radius. Because this is a passive DAC, confirm that both devices support passive SFP+ twinax cables for 10GBase-CR operation. No additional configuration is required at the cable level beyond standard interface settings on the connected devices.

Recommendations

Install the cable in controlled rack environments and avoid sharp bends or repeated flexing. Verify device compatibility and port settings before deployment; if uncertain, request a sample or run a short compatibility test. For longer runs or when optical isolation is required, consider active optical modules or fiber optic cabling instead of a passive SFP+ DAC.
