LC (Lucnet Connector) type connectors have 1.25 mm diameter ferule structure. The abbreviations PC, UPC and APC are definitions expressing the physical differences of the surface geometries of the connectors on the ceramic ferrules. UPC (Ultra Physical Contact) indicates that the ceramic ferule structure on the connector has an extra polished flat structure; APC (Angled Physical Contact) indicates that the ceramic ferrule structure on the connector has an extra polished 8 ° angle structure.
3.0 mm diameter multi fiber cables that consist of 8 fibers (each diameter is 250 micron) that are manufactured with ITU-T G651.OM3 bend sensitive fibers. All fibers tubed (each diameter is 1.8 mm) with use divider that a special solution, in both sides, then assembled at both end with LC type connectors.
