Performance Analysis of CSRZ, MDRZ, NRZ and DPSK Modulation Formats for Two Channel WDM Passive Optical Network

Kamalpreet, Miss Bhawna Utreja

In this paper, we have simulated 2 channel bi directional WDM PON system using CSRZ, NRZ, DPSK and MDRZ modulation formats. System has been analyzed by changing the input power values from -20 to 10dBm. The system is evaluated for 20Gbps bit rate upto 50km in terms of Q factor and eye opening factor. It is found that DPSK is best technique as compared to other modulation formats.
