| Abstract | ||
| The objective of this paper is to highlight the possibility of solving problems corresponding to "the concept of a flexible optical access network." The entire network architecture has been accomplished using the OPTISYSTEM development environment. The WDM-PON system architecture is based on two cascaded Array Waveguide grating (AWG). As compared with standard bidirectional WDM-PON, the system presented in this paper is low cost and more effective. Performance analysis of (NRZ, 0.6 RZ, and 0.8 RZ) modulation formats for both downstream and upstream and the effect of fiber length in them has been investigated. Two different filtering types of AWGs (Gaussian and rectangular) have been evaluated and their effect on the performance of the signal has been compared. Downstream and upstream signals performance was evaluated and optimized with respect to the bandwidth of AWG and the extinction ratio of the downstream signal. | ||
