Cable SFP+ BlueOptics SFP-10G-CU-3M-NE-BL 3 m conector macho/macho

The BlueOptics SFP-10G-CU-3M-NE-BL is a 3-meter passive SFP+ direct attach cable (DAC) with SFP+ male connectors on both ends, designed for short-range 10G interconnects. Built as a twinax copper assembly, it supports 10GBase-CR electrical signalling for linking switches, routers, servers and storage hardware in racks or between adjacent racks. The cable follows MSA-compliant SFP+ form-factor and is intended for environments where low latency, low power consumption and secure short-distance connections are required.

Advantages

This SFP+ 3 m twinax cable provides a cost-effective and energy-efficient alternative to optical transceivers for short links, with passive operation that reduces power draw and simplifies installation. Manufactured from quality components and tested for compatibility with common networking platforms, it offers low latency and a low failure rate typical for passive DAC assemblies. The compact twinax construction and standardized SFP+ connectors enable straightforward deployment in data centre racks and high-density switch ports.

Key specifications

• Cable length: 3 m
• Connector type: SFP+ to SFP+ (male/male)
• Data rate: up to 10 Gbps (10GBase-CR)
• Cable type: passive twinax copper (DAC), 30 AWG conductors
• Colour: black and silver
• Weight: approximately 0.13 kg

How to use

Insert each SFP+ connector into the corresponding SFP+ port on the two devices to be linked, ensuring correct seating until the latch engages. Make sure both devices support passive 10GBase-CR DAC connections. After physical connection, verify link status and negotiate the appropriate 10G interface settings in the device management interface. No external power or transceiver configuration is required for passive operation; standard port configuration and firmware compatibility determine functionality.

Recommendations

Use this 3 m passive SFP+ DAC for short copper links inside racks or between adjacent racks. Verify vendor compatibility with passive SFP+ cables in your hardware documentation before deployment and keep connectors clean and free of dust. Avoid tight bends and mechanical stress on the cable to preserve signal integrity and expected lifetime.
