BlueOptics SFP5141FU2MKB InfiniBand fibre optic cable 2 m MPO 4x LC

The BlueOptics SFP5141FU2MKB InfiniBand fibre optic cable is a 2 m MPO to 4x LC breakout cable designed for multimode OM4 networks. It features an MPO/UPC multi-fiber connector on one end and four LC/UPC duplex connectors on the other, with an 8‑core configuration (pinout 1-4 & 9-12) suitable for QSFP applications. The cable uses 50 µm core multimode OM4 fibre optimized for 850 nm transmission, housed in a flame-retardant LSZH (Low Smoke Zero Halogen) sheath to reduce smoke and avoid halogen emissions in case of fire. The assembly supports full duplex transmission and is manufactured and tested to industry standards for low insertion loss and high return loss.

Advantages

The OM4 multimode construction and precision connectorization deliver low input loss and consistent optical performance across lanes, enabling reliable high-speed InfiniBand links. The MPO to 4x LC breakout format simplifies connections to QSFP and other multi-lane transceivers without splicing, accelerating installation and maintenance. Components use high-quality fibres and ceramic ferrules to ensure long mating life and stable signal transfer. LSZH jacketing and compliance with common safety and telecom norms reduce fire hazard and support use in data centres and enterprise environments.

Suitable for

• High-speed InfiniBand links and multi-lane QSFP connections
• Data centre patching and fibre backbone extensions
• Storage area networks (SAN) and server rack interconnects
• Local area network (LAN) backbone and optical lane aggregation

How to use

Connect the MPO end to the MPO port of an MPO cassette or multi‑lane transceiver such as a QSFP module, and plug the four LC duplex connectors into the corresponding LC ports on target devices or patch panels. Ensure connectors are clean before mating to minimise insertion loss. Use standard cable management practices in racks and enclosures to avoid tight bends or mechanical stress; observe the manufacturer’s minimum bend radius for multimode OM4 fibre. No splicing or field termination is required for breakout use.

Usage recommendations

Inspect and clean connectors with appropriate fibre cleaning tools before installation; store unused connector ends with dust caps. Route the cable to avoid sharp bends and mechanical strain, and secure with non-compressive cable ties or organisers. For permanent installations in critical environments, keep the supplied test report with site documentation and follow local standards for cable trunking and fire safety.
