OLT stands for Optical Line Terminal, a device that connects optical fibers and converts signals. This component plays a vital role in PON, as the PON OLT is the starting point of the entire passive optical network, which is connected to the aggregation layer switches using. OLT (Optical Line Terminal) and switches are critical devices in optical communication networks, but their optical modules differ significantly in types, functionalities, and applications. Let's discuss each one separately: 1. Application Scenario An apartment wants to use the XM60A to enable Omada equipment to access the OLT for networking and flexible deployment. They have the following demands in this example.
