Fibre optic cable Lightwin 5m LC - ST

The Lightwin 5m LC - ST fibre optic cable (OM3) provides a 5-metre link with LC and ST connectors and a 50 µm core diameter, designed for full-duplex data transmission in network environments. The cable uses precision-selected ferrules with minimal bore tolerances to ensure accurate fibre alignment and low core offset during connector assembly.

Advantages

Ferrules used in these assemblies have a maximum bore diameter of 125.5 µm for singlemode-style ferrules and 126.5 µm for multimode variants where applicable, leaving only 0.5 µm clearance for the 125 µm coated fibre. Careful selection of ferrules with tight tolerances reduces core shift and improves coupling accuracy compared with commonly available ferrules that have larger bores and greater variation. This precision helps maintain signal integrity across the OM3 multimode fibre and reduces insertion loss caused by misalignment.

Suitable for

• Short- to medium-range high-speed network links
• Data centres and server room interconnects
• Full-duplex multimode connections using LC and ST interfaces

How to use

Install the Lightwin LC–ST cable by inserting the LC connector into the LC port and the ST connector into the ST port of your devices or patch panels. Ensure both ends are clean and free of dust before connection; use appropriate fibre cleaning tools or lint-free wipes with isopropyl alcohol. When routing the cable, avoid sharp bends and keep bend radius within the manufacturer’s recommendations for multimode OM3 fibre. Secure the cable to prevent strain on connectors and maintain reliable full-duplex transmission.

Usage recommendations

To preserve performance, always inspect and clean ferrule endfaces prior to mating, avoid excessive lateral stress on connectorized ends, and replace any connector showing visible damage or persistent contamination. The precision ferrules reduce alignment issues but do not eliminate the need for proper handling and cleaning.
