SFP+ Cable BlueOptics SFP-10GE-CU-1M-BL 1m Male/Male

The BlueOptics SFP-10GE-CU-1M-BL is a 1 meter SFP+ direct attach cable (DAC) with SFP+ male connectors on both ends, designed for high-speed 10GBase-CR connections. As a passive twinax copper cable with 30 AWG conductors and MSA-compliant SFP+ terminations, it provides a short-reach electrical link between switches, routers, storage arrays and other SFP+ ports in racks and adjacent rack rows. The cable supports 10 Gbit/s protocols such as Ethernet, FCoE and Fibre Channel where passive DAC operation is supported by the host hardware.

Advantages

This passive 1 m SFP+ cable offers low latency and low power consumption compared with active optical modules. Its direct-attach twinax copper construction delivers straightforward plug-and-play connectivity for short-distance links, with reduced component complexity and a low failure rate. The cable’s compact length is suitable for clean rack installations and minimizes excess cabling while maintaining reliable 10 Gbit/s performance.

Suitable for

• Rack-to-rack connections and links between adjacent units within data center racks
• High-speed 10G networking between switches, routers and storage systems
• Short-reach server uplinks and aggregation ports that support passive SFP+ DACs
• Environments where low latency and low power consumption are required

How to use

Ensure both devices explicitly support passive SFP+ DAC cables and the 10GBase-CR protocol. With both network ports powered down or following your equipment vendor’s hot-plug instructions, insert each SFP+ connector into the corresponding SFP+ port until it latches. After connecting, verify link status on both devices and confirm the negotiated speed and protocol. If necessary, consult the switch or server documentation to enable or confirm compatibility with third-party passive DACs.

Recommendations

For optimal performance, use this 1 m passive SFP+ cable for short in-rack and adjacent-rack connections only; avoid using it beyond the intended 1 m distance. Keep connectors clean and avoid sharp bends or excessive strain on the twinax cable. Verify compatibility with your hardware vendor if your system enforces vendor-specific checks for DAC modules.
