Abstract: An optical network which is considered to be the backbone of all the services provided. The networks are able to deliver a bandwidth in a flexible, transparent manner, supports capacity up gradation and backings limit up a degree. The optical system consists of the optical source which acts as a transmitter for the transmission of signal from the optical fiber acting as medium of propagation with cross connects and the photo-transreceivers. There being the confinement of electronic handling of opto-electronic instruments which restrains the full use of transmission capacity. The primary area of concern for the WDM system is to locate the best feasible and reliable way . In case fault occurs in a network, the network needs to be prepared for such situations by providing a fault tolerant network in case of a failure occurring between the source-destination node and assignment of different matrices such as wavelength, feasible path and availability of resources for data transmission in the network. The best path is selected on the basis of a number of factors like delay, capacity etc which are called as performance matrices. The Quality of Service parameters (QoS) are evaluated from these performance matrices. I have outlined three distinctive system topologies having an alternate number of hubs and connections however with the equivalent limit. The networks are then simulated under different scenario to obtain the performance matrices. Those performance matrices are compared with case of network failure and network which is best is proposed under our project consideration for present scenario
