Paper Abstract

The crosstalk effects of Fabry-Perot and grating demultiplexers in Amplified WDM transmission are investigated by taking into consideration of contribution from far channel crosstalk. The crosstalk characteristics of grating demultiplexers is measured to be nearly independent of the channel separation due to device imperfection and dispersion, while the channel crosstalk of the Fabry-Perot demultiplexer assumes Lorentzian form. A unified theory for crosstalk effects of Fabry-Perot and grating demultiplexers is given, and the required fineness for Fabry-Perot demultiplexer and the required crosstalk coefficient for grating demultiplexer are predicted to be 100 and -32 dB respectively to assure 0.5 dB power penalty for a typical 16 channel 350 Km amplified WDM system with 2 nm spacing using SNR equalization method proposed by Dr. A.R. Chraplyvy.
