## Summary description

The Lightwin 7m LC - ST fibre optic cable features OM3 fibre type with a core diameter of 50 µm. It supports full duplex communication, ensuring high-speed data transfer. Ideal for connecting devices with LC and ST connectors, this cable is perfect for network setups requiring reliable and efficient performance.

## Long description

The Lightwin 7m LC - ST fibre optic cable uses a fibre with a total diameter including coating of 125 µm. The ferrule in the connector has a bore sized for this diameter; during assembly the fibre is inserted into the bore, glued and polished. To keep the fibre position reliable, the assemblies use ferrules with a maximum bore diameter of 125.5 µm, leaving only 0.5 µm radial clearance around the fibre.
Advantages
Carefully selected ferrules with tight tolerances reduce lateral displacement of the fibre core and improve alignment between mating connectors. Compared with standard ferrules that often have larger bores, these tighter ferrules limit possible core shift and help maintain signal quality for singlemode and multimode connections. Selection of appropriate ferrule sizes for singlemode and multimode fibres supports consistent performance across installations.
Suitable for
Connecting devices with LC and ST connectors
Short to medium length multimode OM3 links (50 µm core)
Network setups requiring reliable physical alignment of fibre ends
Key specifications
Product: Lightwin fibre optic cable LC - ST, 7 m
Fibre type: OM3 multimode
Core diameter: 50 µm (multimode)
Overall fibre diameter including coating: 125 µm
Ferrule bore (used in assemblies): max. 125.5 µm for singlemode ferrules; 126.5 µm standard singlemode ferrules used for multimode where tolerances are slightly larger
Configuration: full duplex
How to use
Insert the LC and ST connectors into the corresponding ports on your devices, ensuring the connectors are aligned and fully seated. Handle the cable by the connector bodies and avoid bending the cable beyond the manufacturer’s minimum bend radius. Keep connector endfaces clean and free of dust—use appropriate fibre cleaning tools before mating to prevent contamination that can affect signal quality.
Usage recommendations
Use ferrules with tight bore tolerances as supplied to minimize core offset. For best results with OM3 50 µm multimode links, clean connector endfaces before each connection and avoid excessive rotational or lateral stress when inserting fibres into ferrules to preserve alignment and optical performance.
