DAC SFP Cable BlueOptics DAC-SFP-10G-3.0M-BL 3m SFP+ Male/Male

The BlueOptics DAC-SFP-10G-3.0M-BL is a 3-meter Direct Attach Copper (DAC) cable with SFP+ male-to-male connectors, designed for short-distance high-speed links in racks and between adjacent racks. As a passive 10GBase-CR twinax copper cable with 30 AWG conductors and MSA-compliant SFP+ terminations, it supports Ethernet, FCoE, Fibre Channel and InfiniBand protocols up to 10 Gbit/s over a 3 m span. The cable is intended for use with hardware platforms that support passive SFP+ DACs and provides low latency and low power consumption for dense data-center and networking installations.

Advantages

The cable offers a straightforward, low-latency physical connection that requires no external power or active electronics in the cable itself, reducing complexity and points of failure. Manufacturing according to MSA guidelines and the use of high-quality components ensure consistent electrical performance and long service life. With a compact twinax design and industry-standard SFP+ terminations, the cable provides reliable 10 Gbit/s links while keeping power draw and maintenance needs minimal.

Suitable for

• Interconnecting switches, routers and servers within racks
• Short-distance links between adjacent racks in data centers
• High-speed storage and SAN connections supporting FCoE or Fibre Channel
• InfiniBand or other 10G-capable hardware that supports passive SFP+ DACs

Key specifications

• Length: 3 meters
• Connector type: SFP+ male to SFP+ male
• Transmission standard: 10GBase-CR (up to 10 Gbit/s)
• Cable type: Passive twinax copper (DAC)
• Conductor gauge: 30 AWG
• MSA-compliant SFP+ terminations
• Typical power consumption: very low (passive cable, ~0.1 W by host hardware)

How to use

Insert each SFP+ connector into compatible SFP+ ports on the devices to be linked, ensuring the host hardware explicitly supports passive SFP+ DACs. Do not force connectors; they should seat smoothly with the latch mechanism engaged. Verify link parameters and speed on both devices after installation. Route the cable to avoid sharp bends and mechanical strain, and ensure the 3 m length is suitable for the intended rack layout.

Recommendations

Use this DAC cable in environments where short, high-speed connections are required and where the host devices list support for passive SFP+ twinax cables. For optimal longevity, avoid excessive bending, secure the cable to prevent strain on ports, and check compatibility lists of your switches or storage systems. If in doubt, test a sample in your hardware configuration to confirm full functionality.
