WebThe proper design and operation of an optical communication system using optical fibers as the transmission medium requires a knowledge of the transmission characteristics of the optical sources, fibers, and interconnection devices (connectors, couplers, and splices) used to join lengths of fibers together. WebOptical fiber is widely used in long-haul communication systems as a transmission media due to its low attenuation and very high transmission bandwidth. Fiber optic cables are also immune to problems like electromagnetic interference and the light signal in the fiber can be easily amplified in the transmission link.
