Performance Evaluation of Star Topology in Fiber Optic Communication

Topology refers to the layout of connected devices in a network. It describes the way in which the elements of the network are mapped. Optical network topologies such as bus, star and tree reduce complexity by using minimum number of couplers, multiplexers, demultiplexers and optical amplifiers and can reduce cost in large network. Star networks are simplest form of the network topologies. This network topology consists of one central computer, which acts as a central node, to which all other nodes are connected. The performance of star topology is investigated and identified that, it distributes optical power equally to all output ports. Maximum number of users supported by star topology is less than 64.
