The influence of binary modulations in passive optical network based on WDM

Abstract

In this paper, a performance analysis of binary modulation formats in passive optical networks based on wavelength division multiplexing (WDM-PON) has been carried out. WDM-PON offers much higher transmission capacity and longer transmission distance than current PONs using separate wavelengths for each end unit and arrayed waveguide gratings for signal division. Nonlinearities and dispersion effects may affect a performance of transmission system and certain modulation formats can improve a quality of signal so the influence of current modulation formats on the performance of WDM-PON is tested.
