The Core Network Infrastructure
Central OLT and ODN for reliable control
The next generation Passive Optical Network (PON) is a high-speed fiber broadbandsolution that delivers up to 25Gbps data rate in both downstream and upstreamdirections. It is designed to support modern digital demands across residential,business, and Internet of Things (IoT) applications.
The next generation PON offersmulti-services including industrial automation, and connected infrastructures. Businessusers benefit from it for secure, high-performance connections such as cloud access,remote work, and VPNs.
At the core of the system is the Optical Line Terminal(OLT), located at a central office, which connects to the core, metro, and IP backbonenetworks. It manages traffic and communicates with multiple Optical Network Units (ONUs)at end-user locations
through the Optical Distribution Network (ODN). The ODN isoften monitored using Optical Time Domain Reflectometer (OTDR) tools for fault detectionand performance diagnostics.
