BlueOptics SFP5141FU7.5MKB InfiniBand fibre optic cable 7.5 m MPO/UPC 4xDuplex LC/UPC

The BlueOptics SFP5141FU7.5MKB is a 7.5 m OM4 multimode MPO/UPC to 4x Duplex LC/UPC fibre optic breakout cable designed for InfiniBand and high-speed networking links. The cable uses G50/125µm OM4 fibres with an LSZH magenta jacket and 8 cores (pinout 1-4 & 9-12) suitable for QSFP lanes. Measured input loss values are low (MPO < 0.3 dB; LC < 0.2 dB) and each cable is delivered with a measurement protocol that documents insertion loss and return loss values. The assembly is compliant with industry norms for optical performance and safety and is intended for reliable, high-density connections in data centre and enterprise environments.

Advantages

This OM4 MPO to 4x LC breakout cable provides a compact, pre-terminated alternative to splicing, enabling fast installation and straightforward integration with MPO cassettes and QSFP equipment. The LSZH jacket reduces smoke and halogen emission in the event of fire, meeting common safety standards. Connectors use zirconia ceramic ferrules and branded components to ensure consistent end-face quality and a high mating cycle lifetime. Every unit is factory-tested with interferometer and OTDR and shipped with a measurement protocol for quality traceability.

Suitable for

• High-density data centre trunking and top-of-rack connections
• QSFP to LC duplex lane breakout in InfiniBand and Ethernet deployments
• Storage area networks (SAN) and server interconnects
• MPO cassette and patch panel terminations for rapid deployments

How to use

Route the MPO input to an MPO-capable transceiver or cassette and connect the 4x duplex LC ends to the corresponding LC ports on the target devices or patch panels, observing the correct lane pinout. Ensure connectors and adapter housings are clean before mating to minimise insertion loss. Use the included measurement protocol to verify that the measured insertion and return loss meet the expected values for your installation. Avoid tight bends and secure the cable to prevent mechanical strain on the connector interfaces.

Использование — рекомендации

For optimal performance, maintain bend radii above the manufacturer’s minimum, keep connector end-faces protected until final connection, and use compatible MPO cassettes or vendor-recommended adaptors when converting to LC duplex lanes. Regularly inspect and clean connectors in high-density environments to sustain low loss and reliable links.
