InfiniBand/fibre optic cable BlueOptics 74752-1031-BL 0.5 m SFP+ Male/Male

The BlueOptics 74752-1031-BL 0.5 m InfiniBand/fibre optic cable with SFP+ Male/Male connectors is a short-range direct attach solution designed for high-speed links in racks and between adjacent racks. It supports 10G data rates and is suitable for electrical twinax connections where SFP+ transceivers are used. The cable is MSA-compliant and intended for use in data center and enterprise network hardware that supports passive 10GBase-CR direct attach cabling.

Advantages

This 0.5 m cable delivers low-latency 10G connectivity with minimal power consumption due to its passive twinax design. It is constructed from quality components and manufactured to industry MSA standards to ensure interoperability with major networking platforms. The short length reduces signal loss for reliable transmission over short distances, and the fixed SFP+ Male/Male termination simplifies installation in switches, servers and storage systems.

Suitable for

• Top-of-rack and adjacent-rack connections in data centers
• 10 Gigabit Ethernet links (10GBase-CR)
• Fibre Channel, FCoE and InfiniBand short-reach interconnects
• Direct attach between SFP+ ports on switches, routers and servers

Key specifications

• Connector type: SFP+ Male to SFP+ Male
• Length: 0.5 meter
• Data rate: up to 10 Gbit/s
• Cable type: passive twinax copper (Direct Attach Cable)
• Wire gauge: 30 AWG
• Standards: MSA-compliant for SFP+ direct attach use

How to use

Insert each SFP+ connector firmly into the corresponding SFP+ port on your devices until the retention latch engages. Verify that both connected devices support passive 10GBase-CR DAC cables and that port settings match the intended protocol (Ethernet, FCoE, Fibre Channel or InfiniBand). The cable requires no external power or configuration; link negotiation and protocol handling are managed by the connected hardware.

Recommendations

Use this cable for short direct links inside racks or between adjacent racks and avoid routing through cable trays or long conduits that could stress the connectors. Ensure ports explicitly support passive DACs and check firmware or vendor compatibility lists if required. For longer runs or active transceiver requirements, select appropriate fibre optic or active copper solutions.
