Fiber optic patch cable, often called fiber optic patch cord or fiber jumper cable, is a fiber optic cable capped at either end with connector that allows it to be rapidly and conveniently connected to CATV (Cable Television) an optical switch or other telecommunication equipment. Its thick layer of protection is used to connect the optical transmitter, receiver, and the terminal box. This is known as “interconnect-style cabling”.Applications
Fiber optic patch cables are used for wide applications, such as, connections to CATV, telecommunication networks, computer fiber networks and fiber test equipment, including communication rooms, FTTH (Fiber to The Home), LAN (Local Area Network), FOS (fiber optic sensor), Fiber Optic Communication System, optical fiber connected and transmitted equipment, defense combat readiness, etc.Types of Fiber Optic Patch Cables
Fiber optic patch cables can be divided into different types based on varies criteria.
In terms of fiber cable mode, fiber optic patch cables can be described in single-mode and multi-mode fiber patch cables. Single-mode fiber optic patch cables use 9/125 micron bulk single-mode fiber cable and single-mode fiber optic connectors at both ends. Single-mode fiber optic cable jacket color is usually yellow. While multi-mode fiber optic patch cables use 62.5/125 micron or 50/125 micron bulk multi-mode fiber cable and terminated with multi-mode fiber optic connectors at both ends. Multi-mode fiber optic cable jacket color is usually orange.
From fiber cable structure aspect, fiber optic patch cables can be classified into simplex fiber optic patch cables and duplex fiber optic patch cables. Simplex fiber patch cable has one fiber and one connector on each end. Duplex fiber patch cable has two fibers and two connectors on each end. Each fiber uses “A” or “B” or different colored connector boots to mark polarity.
By connector construction standard, fiber optic patch cables include FC, SC, ST, LC, MTRJ, MPO, MU, SMA, FDDI, E2000, DIN4, and D4. Cables are classified by the connectors on either end of the cable; some of the most common cable configurations include FC-FC, FC-SC, FC-LC, FC-ST, SC-SC, and SC-ST.
