SC/APC–LC/APC | Single Mode G657.A2 Duplex Patch Cord | 2.0×4.1mm is a fiber-optic patch cable capped at either end with Fiber optic connectors that allow it to be rapidly and conveniently connected to CATV, an optical switch,Optical Transceiver Modules SFP ,Media converter or other telecommunication and network equipment and switch. Its thick layer of protection is used to connect the optical transmitter, receiver, and the terminal box.
While SC (Square Connector) type connectors have 2.5 mm diameter ferule structure; LC (Lucent 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.
2.0×4.1 mm duplex patch cord cables are manufactured with ITU-T G657.A2 bend sensitive fibers, then assembled at one end with SC type; other end with LC type connectors.
