What is GPON ONU(ONT) and GPON OLT?

Part 1. What Is Gpon Onu (Ont)?Part 2. What Is Gpon Olt?Part 3. How Gpon Onu (ONT) and Gpon Olt Work TogetherThe Bottom LineThe GPON ONU (ONT) and GPON OLT are two primary components that make a GPON network function. The OLT acts as the central point of management and data distribution, while the ONT handles the end-user side, converting the optical signals into usable data for local devices. In this symbiotic relationship, the OLT serves as the upstream gateway for da...See more on vsolcn Cisco
