In this paper the transmission limitations due to the fiber loss and dispersion in optical networks have been investigated, theoretically and experimentally, for three different fibers. An approach for computing the maximum allowable transmission distance imposed by the fiber loss and dispersion as a function of bit rate has been developed. It is found that fiber loss is the dominant factor that determine maximum allowable transmission distance at low bit rate. However, as the bit rate

By comparing the three fibers under study, it is found that, 850nm fiber is the worst in terms of transmission distance, while the 1550nm has superiority over the 1330nm for bit rate <9.5Gb/s. However, for bit rate >9.5Gb/s the 1330nm fiber is better in terms of bit rate and transmission distance. Experimental results for the three fibers (850nm, 1300nm and 1550nm) show a good agreement between the analytical and experimental.
