InfiniBand/fibre optic cable SFP+ BlueOptics 10G-SFP-TWX-P-3M-BL 3m Male/Male

The BlueOptics 10G-SFP-TWX-P-3M-BL is a 3 metre SFP+ direct attach cable (DAC) with SFP+ to SFP+ male connectors designed for short-reach high-speed links. As a passive twinax copper cable it supports 10GBase-CR electrical transmission over a 3 m distance and is compatible with hardware that accepts SFP+ passive DACs. The cable is intended for rack-to-rack or intra-rack connections where low latency, low power consumption and reliable 10 Gbit/s throughput are required.

Advantages

This passive SFP+ twinax cable offers low latency and very low power draw compared with active optical transceivers, making it suitable for dense data centre topologies. The fixed 3 m length simplifies cable management in racks and adjacent rack-to-rack runs. Its SFP+ male-to-male form factor provides direct compatibility with SFP+ ports on switches, routers and storage adapters that support passive DACs. Constructed to MSA-aligned specifications and using quality components, the cable delivers consistent electrical performance for Ethernet, FCoE and InfiniBand applications at 10 Gbit/s over short distances.

Suitable for

• Rack-to-rack connections and intra-rack links in data centres
• 10GBase-CR Ethernet interconnects between switches and servers
• Server and storage adapter connections that support passive SFP+ DACs
• Low-latency applications requiring short-distance high-throughput links

Key specifications

• Interface: SFP+ male to SFP+ male
• Type: Passive twinax direct attach cable (DAC)
• Nominal data rate: 10 Gbit/s
• Maximum recommended length: 3 metres
• Wire gauge: 30 AWG
• Supported protocols: Ethernet (10GBase-CR), FCoE, InfiniBand (where SFP+ passive DAC is supported)

How to use

Insert each SFP+ connector into the corresponding SFP+ port on networking devices or host adapters until the connector latches. Ensure both devices explicitly support passive SFP+ DACs and are powered off or follow hot-plug guidance from the hardware vendor when inserting or removing the cable. After connection, verify link status and speed on both endpoints and confirm that the operating system or switch firmware recognises the link at 10 Gbit/s.

Recommendations

Use this 3 m passive SFP+ twinax cable for short, fixed-length runs inside racks or between adjacent racks. Avoid bending the cable sharply near the connectors and keep it clear of heat sources. Confirm device compatibility with passive DACs and test connections after installation to ensure stable 10 Gbit/s operation.
