SC (Square Connector) type connectors have 2.5 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.
2.0 mm diameter patch cord cables are manufactured with ITU-T G657.A2 bend sensitive fibers, then assembled at both two ends with SC type connectors.
