2.5 General Features
FTTH PON is a point-to-multipoint passive optical network, in which unpowered optical splitters are used
to enable a single optical fiber to serve multiple premises, up to 1:128 (tipically 1:64).
A PON consists of an optical line terminal (OLT) at the central office and a number of optical network
units/terminals (ONU/ONT) at the customer premises. Downstream signals are broadcasted to all
premises sharing multiple fibers. Encryption can prevent eavesdropping. Upstream signals are
combined using a multiple access protocol (Time Division Multiple Access - TDMA). The OLT queues
data to the various ONU/ONT in order to provide time slot assignments for upstream communication.
In Figure 5 it is shown a scenario for a multi-service user domain basic architecture through an ISP
network.
