SFP+ cable BlueOptics SFP-DAC10-3M-BL 3m plug/plug

The BlueOptics SFP-DAC10-3M-BL is a 3-meter SFP+ Direct Attach Cable (DAC) with male SFP+ connectors on both ends, designed for short-reach, high-speed 10G data links. As a passive twinax copper cable compliant with SFP+ MSA, it supports 10GBase-CR signaling and is intended for direct connections between compatible switches, routers, servers and storage systems within racks or across adjacent racks. The cable uses 30 AWG conductors and is optimized for low power consumption and low latency in data center and enterprise networking environments.

Advantages

The cable provides a cost-effective and energy-efficient solution for 10 Gbps connections at short distances without active electronics in the cable. Passive twinax construction delivers low latency and minimal power draw while maintaining signal integrity for supported protocols such as Ethernet, FCoE and Fibre Channel. Manufactured to MSA-compatible design practices, the cable is designed for straightforward deployment with hardware platforms that accept SFP+ DAC modules.

Suitable for

• Direct 10G links between switches in the same rack or adjacent racks
• Server-to-switch and storage-to-switch connections in data centers
• Short-reach 10GBase-CR, FCoE or Fibre Channel links where passive DACs are supported

Key specifications

• Connector type: SFP+ male to SFP+ male
• Length: 3 meters
• Cable type: Passive twinax copper (DAC)
• Supported data rate: up to 10 Gbps
• Wire gauge: 30 AWG
• Standards: SFP+ MSA compatible, supports 10GBase-CR
• Typical applications: Ethernet, FCoE, Fibre Channel

How to use

Install the BlueOptics SFP-DAC10-3M-BL by inserting each SFP+ connector into the SFP+ port of the two devices you intend to link. Ensure both devices explicitly support passive SFP+ DACs and the 10GBase-CR or equivalent protocol in their firmware or configuration. Avoid excessive bending of the twinax cable and secure cable routing within the rack to prevent strain on connectors. No additional transceivers, power sources or configuration changes are required on devices that accept passive SFP+ DACs, although verifying link settings and firmware compatibility is recommended.

Recommendations

Use this 3 m passive SFP+ DAC for short, fixed-length connections inside racks or between adjacent racks where low latency, low power and cost efficiency are priorities. Confirm device vendor compatibility and keep firmware up to date to ensure reliable recognition and operation.
