“…The crosstalk effects can be formulated by assuming that all of the optical multiplexers and demultiplexers have identical characteristics, and that the crosstalk introduced for each channel is also identical. [1] …”

As communication is making the whole world a global village, there seems to be tremendous pressure on the service providers in this field. The greatest demand is for Quality Of Service (QoS) wherein the most important role is played by Interference. There are numerous parameters leading to interference in both wired and wireless communication. In this paper an attempt is made to minimize interference in wired and wireless communication.In wired, an analysis of All Optical Network is carried out whereas in wireless networks, overall interference is reduced using fundamental approach.

“…In the following section, the BER[3]- [6] due to the summation of homodyne crosstalk and Gaussian noise is evaluated according to the characteristic function of the overall noise. Taking the series expansion and found the inverse transform of the characteristic function, the probability density function (pdf) of n(t) is…”

The aim of this paper is to carry out an analysis of optical network by calculating bit error rate (BER) as a function of signal to noise ratio by using Hermitian polynomial for different homodyne crosstalk levels. The results have been plotted for different crosstalk level for BER as a function of single to noise ratio (SNR) by using exact analysis and Gaussian approximation and the results are compared. Simulations have been carried out in MAT Lab Version 7.4. We present an exact analytical probability density function and a closed form bit error rate formula for optical network which performance is degraded by homodyne crosstalk. In homodyne (intrachannel) crosstalk, the interfering signal is at same wavelength as the desired signal. This effect is more severe than interchannel crosstalk (in which interfering signal operates at different wavelength), since the interference falls completely within the receiver bandwidth.

“…The power of this beat term depends on the root of the powers (if the second power is times lower than the first one, the beat term is only lower!). Furthermore this beat term depends on the frequency difference between both channels, on the phase difference in function of the time and on the initial phase difference of both channels by way of a cosine function [23], [26], [27], [37], [38], [40], [43]- [45]. Incoherent crosstalk is defined as the case in which the beat term can be neglected (e.g., when the wavelengths are different).…”

Abstract-This paper presents the results of a crosstalk analysis of four optical wavelength division multiplexed (WDM) cross-connect (OXC) topologies. An optimal set of parameters is determined to reduce the total crosstalk. The scalability of the topologies is presented in terms of wavelengths and input fibers. The total crosstalk in function of the number of cascaded OXC's is compared for the four topologies.Index Terms-Optical communication, optical crosstalk, optical cross connect (OXC), optical switches, optical wavelength conversion, wavelength division multiplexing (WDM).
