InfiniBand/fibre optic cable SFP+ BlueOptics UACC-DAC-SFP10-1M-BL 1m

The BlueOptics UACC-DAC-SFP10-1M-BL is a 1 meter direct attach cable with SFP+ connectors designed for short-range, high-speed connectivity. It is a passive 10GBase-CR twinax copper cable (30 AWG) intended for linking SFP+ ports in racks and adjacent rack systems. The cable supports Ethernet, FCoE, Fibre Channel and InfiniBand protocols at up to 10 Gbit/s over a 1 m distance and is compatible with hardware platforms that support the corresponding SFP+ DAC interfaces.

Advantages

This 1 m DAC offers a low-latency, low-power (passive) connection for short distances where fiber transceivers are not required. Built to MSA-compliant SFP+ form-factor standards and using twinax copper construction, the cable is suitable for direct electrical signal transmission between switches, routers and storage systems. The passive design eliminates active electronics in the cable, reducing power consumption and potential failure points while keeping deployment simple and cost-effective.

Suitable for

• Short-distance links between rack-mounted switches and servers
• Top-of-rack and adjacent-rack interconnects in data centers
• 10G Ethernet, FCoE, Fibre Channel and InfiniBand connections requiring SFP+ interfaces
• Environments where low latency and low power consumption are required

Key specifications

• Connector type: SFP+ to SFP+
• Length: 1 meter
• Media: passive twinax copper (DAC), 30 AWG
• Data rate: up to 10 Gbit/s
• Supported protocols: Ethernet, FCoE, Fibre Channel, InfiniBand
• Form factor: SFP+ MSA compliant

How to use

Insert each SFP+ connector into the corresponding SFP+ port on the two devices to be interconnected while the devices are powered according to the vendor's guidance. Ensure that both devices support passive 10GBase-CR DAC connections and that firmware or software settings permit direct-attach cable operation. Route the cable to avoid sharp bends and mechanical stress; maintain appropriate airflow and clearances inside racks.

Recommendations

Use this 1 m passive DAC for short, fixed connections within racks or between adjacent racks. Verify device compatibility and firmware support for passive DACs before installation. Avoid repeated extreme bending or excessive tensile force and keep the cable away from sources of heat or electromagnetic interference to ensure long-term reliability.
