Abstract
Saudi Arabia's Information and Communication Technology (ICT) industry is undergoing different stages of modernization. Over the last few decades, the ICT industry has been experiencing rapid growth. The understanding of disruption as well as fluctuation in channel capacity gives an idea about the optical fiber network. A primary necessity for the optical communication industry is to achieve the desired effect of survival and growth. Scientific researchers are trying to achieve the objective of optimum optical network services survivability. The proposed paper attempts to describe and analyze the effect of multiplexing in multi-fiber wavelength. To analyze and assess the effect in more scientific and systematic manner, the authors have used a multi criteria decision making (MCDM) approach named the hesitant fuzzy analytical hierarchy process as well as TOPSIS methods in this paper. With the help of these adopted MCDM approaches, the authors have assessed the surviving strength and capacity of multiplexing. For this empirical model, five features and two levels of alternatives were chosen. A combination of two principal alternatives was the first level, and the second level had its five based alternatives. For this analysis, the unified symmetrical decision making strategy of Hesitant-Fuzzy AHP with Hesitant-Fuzzy TOPSIS was established. The findings obtained on survivability in this research will be a point of reference for developing the next level wavelength division multiplexing in optical transmission network communication. In the sense of producing gigabits and terabits per second, this inquiry will further reinforce optical fiber connectivity.
