As optical fibre reaches deeper into passive optical network (PON) in fibre-to-the-x (FTTx) networks, maintaining the integrity of these networks is indeed imperative. Essentially, best practices have been established throughout the installation and verification of the fibre access network. Equally significant is monitoring the optical fibre performance degradation in-service to ascertain efficient service delivery, as well as to guarantee service level agreement. Nevertheless, a minor failure in PON may lead to massive loss of data stemming from inherent passivity of network elements in optical distribution network, thus resulting in customer dissatisfaction and escalated operational expenses borne by network operators. Unfortunately, testing and monitoring optical layer have become rather intricate due to the rapid evolution of PON technology. Hence, an efficient optical layer monitoring system equipped with complete …
