Abstract
Multistage interconnection networks (MINs) have been proposed as interconnecting structures in various types of communication applications ranging from parallel systems, switching architectures, to multicore systems and advances. Optical technologies have drawn the interest for optical implementation in MINs to achieve high bandwidth capacity at the rate of terabits per second. Crosstalk is the major problem with optical interconnections; it not only degrades the performance of network but also disturbs the path of communication signals. To avoid crosstalk in Optical MINs many algorithms have been proposed by many researchers and some of the researchers suppose some solution to improve Zero Algorithm. This paper will be illustrated that is no any crosstalk appears in Zero based algorithms (ZeroX, ZeroY and ZeroXY) in using refine and unique case functions. Through simulation modeling, the Zero based algorithm approach yields the best performance in terms of minimal routing time in and number of passes comparison to the previous algorithms tested for comparison in this paper.

Summary
Multistage interconnection networks (MINs) have been proposed as interconnecting structures in various types of communication applications ranging from parallel systems [1]. OMINs introduce optical crosstalk, which results from coupling two signals within a switching element (SE). Optical crosstalk degrades the performance of OMINs in terms of reduced signal-to-noise ratio and limits the size of the network [5]. Limited by the properties of optical signals, it is not possible to route more than one message simultaneously, without optical crosstalk, over a switching element in an OMIN. There are three main approaches for solving optical crosstalk in OMINs namely the space [6], time [7] and wavelength [8][9] dilation approach. The time dilation approach solves the crosstalk problem by ensuring that only one signal is allowed to pass through each switching element at a given time in the network [11][12]. Optical crosstalk is caused by coupling two signals within a switching element. Illustrate that is Fast ZeroX depends for that is some crosstalk still occurs in ZeroX without author used refine and unique case in ZeroX [15][16]
