## Summary description

The BlueOptics 740-031838-BL is a 5 m InfiniBand/fibre optic cable featuring SFP+ connectors on both ends. Designed for high-speed data transmission, it ensures reliable connectivity for networking applications. The male/male configuration allows for easy integration with compatible devices, making it ideal for data centers and enterprise environments.

## Long description

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.
Usage 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.
