OBD separates the optical signal transmitted by the OLT from the optical bus, and inserts the optical signal from each ONU into the optical bus. Below we will briefly introduce them. For the PON system structure (passive optical network), it is mainly composed of passive components such as optical fiber, passive. PON networks rely on passive components (no power required) to transmit data between a central OLT (located in a telecom central office or data center) and end-user ONTs. Optical splitters are the key passive component that enables “sharing” of OLT resources: Cost Efficiency: A single OLT port can. A passive optical network (PON) is a fiber-optic telecommunications network that uses only unpowered devices to carry signals, as opposed to electronic equipment. In practice, PONs are typically used for the last mile between Internet service providers (ISP) and their customers. 982 gives the reference of PON function configuration, mainly containing three basic functional parts: Optical Line Terminal (OLT), Optical Network Unit (ONU), and Optical.
