EFFECTS OF CROSSTALK ON WAVELENGTH DIVISION MULTIPLEXING SYSTEMS

The effects of ON-OFF keying of the channels on the four wave mixing (FWM) in wavelength division multiplexing (WDM) networks are studied in terms of the distribution of the actual FWM power under different probabilities of channels states. A novel technique for estimating the average FWM power in WDM network with ON-OFF keying is presented. With this technique it is possible to determine the FWM power that associated with each channel in the fiber.
