InfiniBand/fibre optic cable SFP+ BlueOptics MA-CBL-TA-3M-BL 3m Male/Male

The BlueOptics MA-CBL-TA-3M-BL is a 3 m InfiniBand/fibre optic direct attach cable with SFP+ male connectors at both ends. Designed for short-distance, high-speed links, this 10GBase-CR compatible twinax solution supports 10 Gbit/s transmissions between rack-mounted switches, servers and storage systems. The cable is a passive 30 AWG twinax copper assembly complying with MSA specifications for SFP+ direct attach use.

Advantages

The cable provides a low-latency, low-power connection for short links and is compatible with hardware platforms that support standard SFP+ DACs. As a passive direct attach twinax cable, it requires no external power or active components and offers predictable performance and reduced points of failure. Construction according to MSA and use of quality components give it high availability and a long service life suitable for data-centre and rack-to-rack interconnects.

Suitable for

• 10 Gbit/s short-reach connections between switches and servers
• Rack and adjacent-rack uplinks in data centres
• Storage system and SAN interconnects supporting SFP+
• InfiniBand, Ethernet and FCoE applications up to 10 Gbit/s where direct-attach DACs are supported

Key specifications

• Length: 3 meters
• Connector type: SFP+ male to SFP+ male
• Cable type: passive twinax copper (30 AWG)
• Data rate: up to 10 Gbit/s
• Standards: MSA-compliant SFP+ direct attach
• Typical applications: InfiniBand, Ethernet, FCoE, Fibre Channel over short distances

How to use

Install the BlueOptics MA-CBL-TA-3M-BL by inserting each SFP+ plug into the corresponding SFP+ ports on the devices to be connected. Ensure both devices officially support passive SFP+ DACs and that ports are powered down or follow hot‑swap guidance from the device manufacturer if required. After seating the connectors, verify link status and negotiated speed through the host devices' management interface.

Recommendations

Use this 3 m passive DAC for short, direct rack and adjacent-rack connections where low latency and low power are required. Avoid routing near sources of strong electromagnetic interference and do not exceed the intended cable bend radius. Confirm device compatibility with passive 10GBase-CR SFP+ direct attach cables before deployment.
