Paper Abstract

The effect produced by Four-Wave Mixing (FWM) in a Wavelength Division Multiplexing (WDM) transmission is complex to analyze due to its many dependencies. When the optical channels are equally spaced in a WDM transmission, new optical generated signals will fall entirely onto other channels thus causing inband crosstalk. The channel that will suffer from more crosstalk components is that in the middle of the signal band. In this paper we present a theoretical study of the total crosstalk power generated onto each optical channel, equally spaced, using Dispersion Shifted Fiber. Our results show that when the WDM signal range is larger than a certain value, the most degraded channel is not the one that suffers from more contributions but the one that suffers from contributions with higher FWM efficiency. We have studied the limitation that FWM imposes on the number of channels and channel spacing regarding the most degraded channel.
