BlueOptics SFP3133EU50MK InfiniBand fibre optic cable 50 m LC ST

The BlueOptics SFP3133EU50MK is a 50 m duplex InfiniBand fibre optic patch cord with LC/UPC connectors on one end and ST/PC on the other. Built with laser-optimized multimode OM3 fibre (50/125 µm) in aqua jacket, this cable is intended for high-speed 850 nm signal transmission in data centres, server rooms and network racks. The cable uses a flame-retardant LSZH outer jacket and is manufactured and tested to industry standards to ensure consistent attenuation and reliable interconnection between patch panels, transceivers and active equipment.

Advantages

The cable provides low attenuation (≈3.5 dB/km) and high return loss thanks to quality polishing and component selection. BlueOptics uses branded multimode fibres and precision ceramic ferrules to support up to 1500 mating cycles, while production-level interferometer and OTDR testing with a measurement report ensure traceable performance. The LSZH jacket reduces smoke and halogen emissions in case of fire and the assembly complies with common telecom and safety norms.

How to use

Route the duplex cable between the required ports, ensuring the LC and ST connectors are mated to compatible sockets on patch panels, transceivers or devices. Avoid tight bends and secure the cable with appropriate management accessories to maintain the minimum bend radius of multimode OM3 fibre. Before insertion, verify connectors are clean and free of dust; cleaning with appropriate fibre-cleaning tools is recommended to prevent contamination and signal loss. Connectors are keyed for correct polarity—follow your system’s channel mapping for A/B alignment.

Recommendations

Store and handle the cable to prevent kinks and excessive tensile stress. Use dust caps on unused connectors, perform connector cleaning before mating, and consult equipment manufacturer guidance for insertion/removal cycles. For installations requiring custom lengths or specific polish types, request bespoke production to match system requirements.
