Abstract
The efficacy of an optical network is determined by the network's ability to hold out and pull through from failures and disruptions. Achieving the desired impact of survivability is a key imperative for optical network industries. Several practitioners and researchers are working towards realizing the target of maximum survivability of optical network systems. In this league, our research initiative intends to evaluate the impact of survivability of multi-fiber wavelength-division multiplexing networks. To evaluate the impact of survivability factor in optical network through the most accurate means, we used the hybrid multi criteria decision making methodology, the Fuzzy Analytical Hierarchy Process (FAHP) and Fuzzy Technique for Order of Preference by Similarity to Ideal Solution (FTOPSIS). For estimating the impact of survivability in the present endeavour, the authors have taken two layers (two factors at level 1, and 10 factors at level 2) of the survivability factors for calculating the weights and five alternatives for evaluating the survivability impact. The hybrid technique of FAHP and FTOPSIS was developed for our analysis. FAHP evaluated the weights of the factors with respect to their alternatives, whereas the FTOPSIS was employed to calculate the overall impact of survivability. According to the numerical analysis of the selected factors affecting the parameters of the survivability in Wavelength Division Multiplexing (WDM), restoration technique was the most prioritized alternative, and hence needs more focus while engineering the WDM network.

The fuzzy approach of the following methodology has been used in Wavelength Division Multiplexing (WDM): The engineers selected the alternatives according to their needs and affixed the initial values according to the quantitative impact of the survivability in WDM OFNC from the proper result, i.e., weights and ranks of the research study
To evaluate the impact of survivability in WDM optical fiber network, we evaluated the factors and their dependent alternatives through the hybrid approach of Fuzzy Analytical Hierarchy Process (FAHP) and FTOPSIS
Summary
The network survivability in Optical Fiber Network Communication (OFNC) ensures the uninterrupted services by the network operator [1]. Tsunami, flood, etc., may cause disruption in OFNC. Network failures can result in the loss of data during any kind ofdisruption, creating problems for both the sender and receiver [2]. For achieving the target of seamless and uninterrupted services, consistent inventiveness of restoration and protection techniques become an imminent prerequisite. Network or data loss during the data transmission or communication between two or more parties can be restored by the factor known as survivability. The network uses carrier WDM defined as bidirectional multi signal optical communication by the laser light. To secure the optical network from the natural or manmade disasters, we need to secure the communication by the factor of survivability in WDM network.
