Amidst improved parameters in an optical communications system, fiber optic links are inundated with challenges of validating network key performance indices of throughput, latency, and packet jitter and frame loss rates. These metrics cover. The mitigation measures for the above causes were discussed in this paper and they include upgrading the bandwidth of the link, ensuring the use of quality fiber cables, regular maintenance in order to sight out the faulty components on the link as well as employment of several repeaters on long. This Applications Engineering Note (AEN 135) explains and recommends standard measurement methods for characterizing optical fiber system performance. This note also provides background information on system link configurations, test equipment and system component considerations that influence. The global broadband market is shifting towards fiber-optic technologies, with a subscriber growth rate in Europe of 28% from 2021-2023. FTTX networks are a generalization for different configurations of fiber deployment.
