Abstract

A hybrid TDM/WDM PON network with 64 users was designed by a bidirectional optical fiber in this paper. Having analyzed the performance of the hybrid network with regard to the importance of photodetectors as the first receiving block, the performance of photodetectors PON and APN for different fiber lengths are compared. All designing procedures were performed by optisystem software and measured values were represented and evaluated. As expected, the result showed that, due to an increase in the length of the fiber, the amount of noise increased and consequently, the signal to noise ratio decreased. However, it was found that the used topology was able to receive information in both upstream and downstream for fibers with a length up to 30 km and parameters of Q factor, the bit error ratio, and the signal to noise ratio are desired and acceptable for fibers of 30 km length. In addition, the values of simulations show that the performance of APD diode and the Q factor and BER obtained from APD is better than that of PIN which could be expected because APD is more sensitive than PIN.
