InfiniBand/kuitu-kaapeli BlueOptics 740-031838-BL 5 m SFP+ uros/uros

The BlueOptics 740-031838-BL is a 5 m InfiniBand/fibre optic cable with SFP+ male connectors on both ends. Engineered for short-reach high-speed links, this cable supports 10G data transmission and is intended for direct connections between SFP+ ports in racks and adjacent rack systems. The cable is suitable for environments that require low-latency, reliable links such as data centres, storage networks and enterprise switching environments.

Advantages

This SFP+ cable offers a passive direct-attach solution that delivers a low-power, low-latency connection for up to 10 Gbit/s over a 5 m distance. Constructed to meet common MSA standards and using quality components, the cable provides stable physical connectivity and broad compatibility with devices that accept SFP+ direct attach cables. The male-to-male SFP+ configuration enables simple plug-and-play integration with compatible switches, routers and storage hardware without additional transceivers.

Suitable for

• Short-reach 10G connections between switches in the same rack or adjacent racks
• Server-to-switch or storage-to-switch links in data centre racks
• Fibre Channel, Ethernet and InfiniBand applications at up to 10 Gbit/s where SFP+ direct attach is supported

Key specifications

• Connector type: SFP+ male to SFP+ male
• Length: 5 metres
• Supported data rate: up to 10 Gbit/s
• Cable type: passive direct attach (twinax copper for short-range electrical transfer)
• Compliance: MSA-compliant SFP+ form factor and electrical signalling for direct attach use

How to use

Install the cable by inserting each SFP+ connector into the corresponding SFP+ port on your devices until the latch clicks. Ensure both devices support passive SFP+ direct attach cables and the same transmission protocol (Ethernet, FCoE, Fibre Channel or InfiniBand at the intended speed). Route the cable within the rack or between adjacent racks avoiding sharp bends and mechanical strain. No additional configuration is required on most systems, but verify link status and speed in the device management interface after connecting.

Recommendations

For reliable operation, keep cable bend radius within manufacturer limits, avoid excessive stress on the SFP+ connectors, and use the cable for short-range connections up to 5 m as intended. Confirm hardware compatibility with passive DAC cables in the device documentation and test new links during maintenance windows to verify performance and firmware interoperability.
