Components and Architecture of GPON FTTH Access Network
PON (Passive optical network) based FTTH access network is a point-to-multipoint, fiber to the premises network architecture in which unpowered optical splitters are used to enable a single optical fiber to serve 32-128 premises. FTTH network exploits the low attenuation and high bandwidth of single-mode fiber to provide many times more bandwidth than currently available with existing broadband technologies. The components and architecture of GPON FTTH access network will be explained in this paper. Components of GPON FTTH Access Network Optical line terminal, optical splitters and optical network terminal are the three components of GPON FTTH access network. OLT (Optical Line Terminal) The optical line terminal is the main element of the network and it is usually placed in the local exchange. It is the engine that drives FTTH system. Traffic scheduling, buffer control and bandwidth allocation are the most important functions of optical line terminal. Typically, OLT operat...
