Paper Abstract

The performance of Manchester-coded optical wavelength division multiplexing (WDM) systems is evaluated taking into account the shot noise and the four wave mixing (FWM) caused by fiber nonlinearities. The result is compared to conventional non-return-to-zero (NRZ) systems for ASK and DPSK modulation formats. Further, the dynamic range, defined as the ratio of the maximum transmitter power (limited by the FWM) to the minimum transmitter power (limited by receiver sensitivity) is evaluated. For 1.55 micrometers 16 channel WDM systems, the dynamic range of Manchester coded systems show as 2 dB improvement with respect to the NRZ; DPSK systems outperform ASK systems by 5.5 dB. This result holds true for both dispersion-shifted fiber and conventional fiber; it has been obtained for 10 GHz channel spacing, 1 Gbps/channel bit rate and 100 Km transmission length.
