BlueOptics SFP3131EU7.5MK InfiniBand kuitu- kaapeli 7,5 m LC aqua

The BlueOptics SFP3131EU7.5MK is a 7.5 m OM3 multimode fibre optic duplex patch cord with LC/UPC connectors in aqua. Designed for 850 nm transmission, this LC–LC cable uses 50/125 µm laser-optimized multimode fiber (LOMMF) to enable full-duplex, high-speed links between patch panels, optical transceivers and active equipment in data centres and enterprise networks. The cable is jacketed in flame-retardant LSZH material for reduced smoke and no halogen release in fire scenarios.

Advantages

This fibre patch cord offers low attenuation (approximately 3.5 dB/km) and high return loss; connector polishing options such as UPC are used to further optimise back reflection. Components are sourced from recognised manufacturers and use zirconia ceramic ferrules that support long connector life and up to 1500 mating cycles. Each cable is tested with interferometer and OTDR and delivered with a measurement protocol for insertion loss and return loss, ensuring reliable, traceable performance.

Key specifications

How to use

Inspect both connectors and ports for contamination before connecting; use appropriate dust caps until installation. Route the cable following rack and cable-management best practices, avoiding tight bends and excessive torsion; respect the manufacturer’s minimum bend radius for multimode patch cords. Insert the LC duplex connectors into the corresponding LC ports until they click; ensure correct polarity if required by the link design. For links to optical transceivers, follow the transceiver and switch vendor instructions for hot-plugging and handling.

Recommendations

Store and install the cable in controlled environments and avoid sharp bends or crushing. Use labelled patching and maintain the supplied test protocol for link documentation and troubleshooting. For environments with longer reach requirements, verify that OM3 multimode performance meets the link budget and consider single-mode alternatives if necessary.
