OverviewVariantsComponents and characteristicsHistoryNetwork elementsUpstream bandwidth allocationEnabling technologiesFiber to the premises

For TDM-PON, a passive optical splitter is used in the optical distribution network. In the upstream direction, each ONU (optical network units) or ONT (optical network terminal) burst transmits for an assigned time-slot (multiplexed in the time domain). In this way, the OLT is receiving signals from only one ONU or ONT at any point in time. In the downstream direction, the OLT (usually) continuously transmits (or may burst transmit). ONUs or ONTs see their own data through the address labels embe

The Role of GPON ONU (ONT) and GPON OLT in Fiber

These slots are allocated to each ONU according to the upstream bandwidth map field in the downstream frame, enabling each ONU to send data

Understand GPON Technology

The OLT is connected to the optical splitter through a single optical fiber, and then the optical splitter connects to ONUs/ONTs. GPON adopts WDM to transmit data of different upstream/downstream

Introduction To Data Transmission Methods In PON
