LC (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.

0.9 mm diameter pigtail cables are manufactured with easy-to-strip tubes and ITU-T G657.A1 bend sensitive fibers, then assembled at one end with SC type connector. TIA / EIA-598 color standard is used for 12-color pigtail sets.
