Fiber Optic Cable Assemblies
Fiber optic cable is a network cable that consists of one or more strands of glass enclosed in an insulated casing. They are designed for high-performance data networking over long distances at the speed of light. There are two main types of fiber optic cables: single-mode and multi-mode. Single-mode cables have a very thin core that the signal travels straight down. They send information over 60 miles and are used for internet, telephone and tv signals. Multi-mode cables are 10 times bigger than single-mode with a variety of paths that light can travel through. They send information over shorter distances and are commonly used to link computer networks together.
Fiber optic cable assemblies come with the proper connectors attached to the ends of the cable. The type of connector depends on the type of optical fiber and the intended use of the assembly. The five most common connectors are: FC, LC, MT-RJ, SC and ST.
Fixed Connectors (FC) are designed with a threaded end that screws on to the barrel housing. Because the connectors are fixed to the cable, the connection is secure enough for high vibration applications.
Lucent Connectors (LC) are designed with a ceramic ferrule that is half the size of an ST ferrule. They are widely used with single-mode fibers in cable assemblies.
Mechanical Transfer Registered Jack Connectors (MT-RJ) are often used with small devices because of their size. They were originally designed to replace SC connectors and are used in conjunction with dual-fiber cables.
Subscriber Connector Connectors (SC) are ceramic ferrules that are designed as a push-pull device for use with dual-fiber cables. They offer low-cost durability and simple installation.
