“…In an optical network designed according to the DWDM standard, for which the channels are 100 GHz (0.8 nm) apart, there is a maximum of 1 dB of power loss per channel due to FWM. That is, if the power attributed to all channels has a P-value, then the power loss for each channel must be less than P. The FWM effect increases as the length of the transmission line increases and this limits the performance of the individual channels [19]. The dependence of the maximum transmitted power per channel (mW) versus distance (km) for standard SMF fiber and DSF fiber is shown in Figure 3 [20].…”

This paper aims to point out the nonlinear phenomenon occurring in coarse/dense wavelength division multiplex (C/D-WDM) systems. This phenomenon has to be taken into account during the design of the optical network itself, as wavelengths in the optical fiber are constantly densified. The paper points out the emergence of the non-linear four-wave mixing (FWM) phenomenon and how it relates to the dispersion in the optical fiber together with the transmit power. The output of the paper is a proposed design of the system that points to the improvement of the bit error rate (BER) with a suitable choice of dispersion and suitable transmission power.

For the modulation of various data streams, Wavelength division multiplexing is utilized. Further, Dense Wavelength Division multiplexing is the type of WDM which is capable of spacing the wavelengths more closely due to its greater capacity. This technology is widely used in fiber optics as it utilizes the bandwidth in an appropriate manner. Various researchers have been carried out to make it worth using. Recently, in research, the author had used DWDM in clear weather conditions and turbulence generated in a channel. In this work, the author had utilized the RZ modulation technique which has some drawbacks. Due to this, the performance of the entire model is affected. Thus in this paper, a novel approach is presented to overcome the problems of the existing system. In the novel system, RZ encoding is replaced by Manchester encoding. Manchester encoding has several advantages over RZ encoding. Further, the simulation of the model is performed under the optisystem. Here, the Q-factor of both (proposed and with RZ encoding) models are determined in terms of a single channel, 4 channels, and 16 channels. The results showed the effectiveness of the proposed system as it increases the quality of the signal transmitted from one source to another.
