摘要：Influence of different materials on graded index optical fiber systems was studied, these materials(channel 1 has a core made from PMMA+ and cladding of carbon fluorine polymer,channel 2has a core made from Polystyrene PS++ and cladding of Polymer PMMA+,the third channel has the core made from Silica with cladding of Silicon resin), were examined for their effect on quality factor ,total output power (dBm) and intermodal dispersion at the receiver.All the channels operated at the same optical transmitted with non return-to-zero (NRZ).Performance study was done for variable lengths of fiber 1, 2, 3, 4 km for these different material channelsby simulating a model of communication system.Optisystem software has been used for this simulation.Results reveal the ability of improving the graded index fiber characteristics by using these materials and theoptimum effect concluded at(20dBm) input powerby using the third channel material i.e.the quality factor and total output power were increased to reach(374.2 ) and (-9.073 dBm) respectively and intermodal dispersion decreased to reach(11.822 ns/km).
