Optical fiber coupler have the same functionality like electronic couplers: The signal is split into multiple points(devices). For tapping (monitoring the signal quality) or more complex telecommunication systems fiber optic couplers are required which need more than simple point-to-point connections, such as ring architectures, bus architectures and star architectures. Fiber optic couplers are either active or passive devices. Between active and passive couplers the major difference is that a passive coupler without optical-to-electrical conversion redistributes the optical signal. Active couplers are electronic devices that split or combine the signal electrically and they make use of fiber optic detectors and sources for input and output. Electronic couplers are easy to make because as long as you have physical contact between conductor’s there is flow of electric current. Fiber optic coupler types are defined by their input and output port numbers. They are basically designed to fulfill different applications.
