OFNR (Riser) rated jacket with Kevlar yarn, and are factory terminated resulting in uncompromised performance. GT-SCSCDM4A-xM fiber optic patch cords are ideal for short distance patching. What materials are fiber optic cables made of? The core part of the cable is made from glass or plastic optical fiber, while the cladding is usually made from fluoride-doped silica. What's the. The fiber optic patch cable must, therefore, be carefully considered. Patch cords can be simplex or duplex. A simplex cable consists of a single strand of optic fiber.
