InfiniBand/fibre optic cable SFP+ BlueOptics UACC-DAC-SFP10-0.5M-BL 0.5m

The BlueOptics UACC-DAC-SFP10-0.5M-BL is a 0.5 m SFP+ direct attach cable (DAC) designed for short-reach 10G connections in InfiniBand, Ethernet and Fibre Channel environments. This passive twinax copper cable has SFP+ connectors on both ends and supports 10GBase-CR signalling for linking switches, servers and storage devices within racks or between adjacent racks. The cable is MSA-compliant and intended for use where a short, low-latency, low-power physical link is required.

Advantages

The cable offers low latency and low power consumption typical of passive DACs, and benefits from a compact 0.5 m length that reduces signal attenuation and cabling clutter in dense rack environments. MSA-compliant SFP+ terminations ensure broad compatibility with networking hardware that supports passive SFP+ DACs. The twinax copper construction provides reliable electrical transmission for short distances and a long operational lifetime when used according to manufacturer specifications.

Suitable for

• Connecting top-of-rack switches to servers or storage within the same rack
• Short-distance links between adjacent racks in data centers
• 10G Ethernet, FCoE and InfiniBand connections where passive SFP+ DACs are supported

Key specifications

• Length: 0.5 meter
• Connector type: SFP+ to SFP+
• Data rate: up to 10 Gbit/s
• Cable type: passive twinax copper (30 AWG)
• Protocol support: 10GBase-CR, Ethernet, FCoE, Fibre Channel and InfiniBand (where supported)
• Form factor: SFP+ MSA-compliant

How to use

Insert one SFP+ connector into the SFP+ port of the first device and the other connector into the corresponding SFP+ port of the second device, ensuring both devices support passive DAC connections. Secure the connectors by engaging the SFP+ latch mechanism. No external power or transceiver modules are required because the cable is passive; link configuration and speed negotiation are managed by the connected equipment according to their network settings and supported protocols.

Recommendations

Use this 0.5 m DAC for short, intra-rack or adjacent-rack connections where low latency and low power consumption are priorities. Verify device compatibility with passive SFP+ DACs beforehand and avoid bending the cable sharply; maintain the manufacturer’s recommended bend radius to preserve signal integrity and longevity.
