Performance Analysis of Modulation Formats for Next Generation Passive Optical Networks

Abstract

In this paper comparison of efficient binary modulation formats like Chirped-NRZ, Chirped-RZ, RZ-50 %, Duobinary and AMI is carried out for GPON networks. Their performance is questioned in terms of bit rates versus link length. Chirped-NRZ comes out to be optimal modulation format for high speed and long reach optical communication. Quality of the received signal is analyzed by considering parameters like Q-factor and BER.
