Fiber Closure patch cord is one of most commonly used components in fiber optic network. fiber optic patch cords sometimes is also called fiber optic jumper or fiber optic patch cables. generally there are two types of fiber optic patch cords: single mode fiber optic patch cords and multimode fiber optic patch cords. here the word mode means the transmitting mode of the fiber optic light in the fiber optic cable core. usually single mode fiber optic patch cord are with 9/125 fiber glass and is yellow jacket color, multi mode fiber optic patch cord are with 50/125 or 62.5/125 fiber glass and is orange color. Fiber optic patchcord are used for linking the equipment and components in the fiber optic network ,they are with various kinds of fiber optic connector types. the fiber optic patch cord types are classfied by the fiber optic connector types.for example,we name LC fiber optic patch cord because this cable is with LC fiber optic connector.there are PC,UPC,APC type fiber patch cord, they are different because of the polish of fiber connectors. Fiber optic patch cord are with various kinds of cables,PVC, Riser, Plenum, OFNR,OFNP,LSZH (LSOH),10 Gig Aqua, there are simplex fiber optic patch cord and duplex fiber optic patch cord and multi fiber cable assemblies,and there are ribbon fan out fiber cable assemblies and bundle fiber optic cable assemblies.Typical fiber optic patch cord cable diameter can be 0.9mm,2mm,or 3mm. LC Fiber Optic Patch Cord LC is the short form of Lucent Connector, LC fiber patch cord connector is a push and latch structure, with plastic housing and accurate 1.25mm ceramic ferrule. LC type is a popular kind of small form fiber optic patch cord which reduce the space and it is widely used for densely installation. E2000 Fiber Optic Patch Cord E2000 fiber optic patch cord is one of the latest style yet one of the most expensive cable.Developed by Diamond, E2000 features a spring-loaded shutter used to protect the ferrule from dust and scratches. E2000 fiber connectors is similar size of SC fiber connectors. SC Fiber Optic Patch Cord The SC fiber optic patch cord was invented by the Japanese company NTT. It is one of the most widely used fiber optic patch cords. SC fiber optic patch cord features low cost , simplicity as well as good durability, SC fiber optic patch cords is with a locking tab on the cable termination, it is a push and pull type fiber optic connector.
