Performance Evaluation of DWDM/MPLS/SDH/CWDM Equipment in PowerGrid’s Telecom Network in North East India

Abstract

This study evaluates the performance of DWDM, MPLS, SDH, and CWDM equipment deployed by Powergrid from three major vendors—Fiberhome, ZTE, and Tejas. Data was collected from Points of Presence (PoPs) in Guwahati, Shillong, and Itanagar. The performance was analyzed based on key factors such as battery bank health, air conditioner efficiency, PIU health, and DCPS health. Additionally, the study investigates fault rates, card failures, and SFP failures across different locations. The research methods include tests such as battery bank discharge analysis, air conditioner cooling efficiency, and PIU performance tests. The results highlight the direct relationship between supporting infrastructure and the performance of optical communication systems, offering recommendations for improving network reliability.
