BlueOptics SFP5141BU7.5MKB InfiniBand fibre optic cable 7.5 m MPO/APC 4xLC/UPC

The BlueOptics SFP5141BU7.5MKB is a 7.5 m InfiniBand fibre optic breakout cable with an MPO/APC multi-fiber connector on one end and four duplex LC/UPC connectors on the other. Designed as single-mode fibre (E9/125 µm, G.657.A1), the cable supports full duplex high-speed data transmission across optical lanes and covers wavelength ranges commonly used in networking equipment. The cable uses an LSZH (Low Smoke Zero Halogen) sheath and contains eight cores, offering a compact, flame-retardant solution for short to mid-range connections in data centres and network racks.

Advantages

The MPO to 4xLC breakout design allows rapid deployment without splicing or special assembly tools, reducing installation time and simplifying upgrades. Low insertion loss values (MPO under 0.3 dB, LC under 0.2 dB) and high return loss deliver reliable signal integrity. Components use branded fibres and precision ceramic ferrules to ensure long connector life and consistent optical performance. The LSZH jacket reduces smoke and halogen emissions in case of fire and the cable is manufactured to meet common industry standards.

Key specifications

How to use

Connect the MPO/APC end to a compatible MPO trunk, cassette or transceiver input and plug each LC/UPC duplex connector into the corresponding LC ports of switches, patch panels or transceivers. Observe correct polarity and connector orientation to maintain lane mapping. No field splicing or polishing is required; the pre-terminated breakout assembly enables immediate use after installation. Handle connectors by their housing, keep endfaces clean, and use appropriate dust caps until final mating.

Recommendations

Before deployment, verify polarity and lane mapping against the target MPO cassette or patch panel. Use a fibre inspection microscope to check connector endfaces and perform cleaning if contamination is present. Avoid tight bends below the cable's minimum bend radius and route the cable in protected trays or cable managers to prevent mechanical stress. Keep the supplied measurement protocol for acceptance testing and documentation.
