Abstract: The allocation of power losses between optical source and detector is referred to as the power budget. To ensure that the fiber system has sufficient power for correct operation, we need to calculate the span’s power budget, which is the maximum amount of power it can transmit. Transmission distance depends on transmitter output power, receiver’s sensitivity, fiber quality, splice loss, connector loss, safety margin and signal losses caused by other factors. The reliability or performance of a fiber optic communication system can be enhanced through careful selection and matching of all the subparts (transmitter, fiber optic, receiver, connectors).The optic fiber should be matched and verified according to its applications. It should be stresses that the optimization of communication system based on fiber optics has quite a number of parameters. The only way to enhance on such system is to use a thorough designing approach and tuning it with the feed-back received from an economical analysis.
