ABSTRACT: It is expected that users of telecommunication services such as Internet, Web browsing, and tele-education will increase ramatically. This has greatly increased the demand for high bandwidth and high capacity communication systems. Advances in electro-optic technologies have made optical communication a good networking choice for the increasing demands of high channel bandwidth and low ommunication latency of high-performance computing and communicationapplications. Optical Multistage Interconnection Networks (OMINs) are very popular in switching and communication applications and have been used in telecommunications and parallel computing systems. Butthere are some problems in optical multistage interconnection Networks such as the optical-loss during switching and the crosstalk problem in the optical switches. The major problem called crosstalk is caused by coupling of two signals within a switching element. A lotof work has already been done in designing various algorithms and methods so that good quality solution can be obtained. In this paper, some methods to avoid crosstalk are compared and checked.
