Architecture of PON
PON is a passive network featuring one to multiple point architecture.
PON consists of Optical Line Terminal (OLT), Optical Network Unit (ONU) and Passive Optical Splitter.
TDM PON play an important role in all access of optical access network solutions to distribute reasonably high bandwidth to the customers through an optical fiber network infrastructure.
Due to lower maintenance costs and more reliable operation network operators tend to support the TDM-PON scheme.
However, the bandwidth provided by one wavelength is shared by the whole optical network units in the network because the time division multiplexing passive optical network architecture provides only limited scope for improving the bandwidth performance.
