2.5 General Features
GPON is a point-to-multipoint passive optical network, in which unpowered optical splitters are used to enable a single optical ber to serve
multiple premises, typically 1-64.
A PON consists of an optical line terminal (OLT) at the central oce and a number of optical network terminals (ONT) at the customer premises.
Downstream signals are broadcasted to all premises sharing multiple bers. Encryption can prevent eavesdropping. Upstream signals are com-
bined using a multiple access protocol (Time Division Multiple Access- TDMA). The OLT queues data to the various ONT terminals in order to pro-
vide time slot assignments for upstream communication.
In Figure 2-5 it is shown a scenario for a multi-service user domain basic architecture through an ISP network.
