6.2 Passive Optical Network (PON) System
The general architecture of a Passive Optical Network (PON) access network
consists of two key elements: the Optical Line Termination (OLT) and the Optical
Network Unit (ONU). The OLT is connected to the ONU through a point-to-
multipoint Passive Optical Network that consists of fiber, splitters and other
passive components. Typically, up to 32 ONUs are connected to a single OLT,
depending on the splitting factor. OLTs are typically located in local exchanges
and ONUs on street locations, in buildings or even in homes.
Figure 2 shows the use of the AAL1gator-32 in an OLT application supporting
CES functions. Note that the PM73123 AAL1gator-8 or PM73124 AAL1gator-4
can be used in ONUs to provide the reciprocal CES functions to the OLT.
