DAC SFP Cable BlueOptics DAC-SFP-10G-3M-DE-BL 3m SFP+ Male/Male

The BlueOptics DAC-SFP-10G-3M-DE-BL is a 3 metre Direct Attach Copper (DAC) cable with SFP+ male connectors on both ends, designed for short-reach, high-speed interconnects. It supports 10GBase-CR electrical signalling and is suitable for linking switches, routers and servers in rack and adjacent-rack environments. The cable uses a twinax copper assembly and 30 AWG conductors to deliver low-latency, low-power transmission for Ethernet, FCoE and similar protocols up to 10 Gbit/s over a 3 metre distance.

Advantages

The DAC-SFP-10G-3M-DE-BL provides a plug-and-play copper connection with predictable electrical performance and minimal power draw compared with active optical transceivers. Its SFP+ to SFP+ form factor ensures broad compatibility with hardware platforms that support passive DACs, while the twinax construction and quality components contribute to reliable signal integrity and long operational lifetime. Passive design eliminates onboard active electronics, reducing failure points and keeping latency and energy consumption low.

Suitable for

• Short-distance server-to-switch or switch-to-switch links in data centres and server rooms
• Top-of-rack and adjacent-rack interconnects where economies and low latency are priorities
• Connecting storage systems, routers and other network appliances that accept SFP+ passive DACs

Key specifications

• Length: 3 metres
• Connector type: SFP+ male to SFP+ male
• Data rate support: up to 10 Gbit/s
• Cable type: passive twinax copper (Direct Attach Copper)
• Wire gauge: 30 AWG twinax
• Supported protocols: Ethernet and compatible high-speed protocols such as FCoE and Fibre Channel over supported hardware
• Typical power consumption: very low (passive cable, no active electronics)

How to use

Install the DAC-SFP-10G-3M-DE-BL by inserting each SFP+ connector into the corresponding SFP+ port on networking devices until the latch engages. Ensure both devices support passive SFP+ DAC connections and configure link settings (speed/duplex) on the connected equipment if required. For best signal integrity, avoid bending the cable beyond manufacturer-recommended bend radii and route it to minimise mechanical stress and electromagnetic interference sources.

Recommendations

Use this 3 m passive DAC for short-range interconnects within racks or between adjacent racks where 10 Gbit/s connectivity and low latency are required. Verify hardware compatibility with passive twinax SFP+ modules before deployment and keep the cable within recommended cable management paths to preserve longevity and performance.
