Performance Indicators of Fiber Optic Communication Systems
Therefore, this study seeks to analyze the key performance requirements (latency, throughput, packet jitter, and frame loss rate) in optical communications links for optimal network performance and end-user quality of experience. Fundamentally, a fiber optic network comprises of strands of glass or plastic fibers, encased within a protective sheath, that transmit light. This paper presents how different tests of throughput and latency were carried out using Viavi test kit, analyzed and then after compared the obtained results with the standard defined by IEEE and ITU for conformity. The organization of the rest of this paper is as follows. The paper. Optical communication systems have become the backbone of modern telecommunications, enabling the transmission of large amounts of data over long distances with minimal loss.
