Performance Analysis of 2.5Gb/s Bidirectional WDM/TDM-PON with Narrowband AWG for Varying Extinction Ratio using ANFIS
نویسندگان
چکیده
In the present work, we investigate the impact of extinction ratio (ζ) of Mach-Zehnder (MZ) amplitude modulator on the performance of 2.5Gb/s Wavelength Division Multiplexed Passive Optical Networks (WDM-PONs) for optical fiber length varying upto 60km. The system performance has been analyzed by varying the value of ζ from 2 to 22dB. It is found that the system gives optimum performance at extinction ratio value 20dB beyond which it saturates. Further, the fuzzy model of the system is developed using ANFIS (Adaptive Neuro-Fuzzy Inference System), for varying extinction ratio of MZ modulator and performance is evaluated by comparing simulated results with fuzzy model and good correlation is achieved between them.
