ABSTRACT Development of wavelength division multiplexing technologies and increased transparency in the networks has tremendously increased the information carrying capacity of fiber optic networks. However, these networks are affected by accumulation of optical impairments along the lightpath resulting in degradation of signal being transmitted thereby creating inadequacy to meet quality of service requirements. In this article, effort has been put in to identify different parameters affecting the signal quality. A technique to measure these parameters and their application in connection provisioning is presented. Electrical postprocessing techniques are implemented to calculate quality of link path. The algorithm designed consider the quality of lightpath for connection provisioning for each connection requirement based on first fit, best fit, and shortest path principle. The performance of designed algorithm has been verified by presenting different quality conditions of transmission links and optimal results are obtained. © 2015 Wiley Periodicals, Inc.
