ABSTRACT
In this paper we demonstrate performance of three different optical filter transfer functions: Lorentzian, Raised Cosine and Supergaussian, and their influence on non-return-to-zero (NRZ) coded optical signal in high density WDM (HDWDM) systems. The effect of filter bandwidth at -3 dB influence on NRZ and spectral narrowing on signal quality has been studied extensively. We foresee that for 10 Gbit/s data transmission speed NRZ coded optical signal optimal filter bandwidth at -3 dB level referred to full width half maximum (FWHM) value must be greater than 0.1 nm or 12.5 GHz.
