Modified Unequally Spaced Channels Wavelength Division Multiplexing System
مجلة علوم ذي قار, 2019 The channels contributed in creating new pulse during the four-wave mixing (FWM) process are a subject of two features: the first is the fact that all channels are not working with probability %100 , but with p probability.
