Abstract:
This thesis sets forth the technical functionality of Optical Fiber & Optical Fiber Access Network (OF AN) in general and particular for Islamabad. The objective of every Telco is to introduce fiber optic cabling nearer to the subscriber, initially up to the curb or the building, and thereby create the necessary infrastructure for the future broadband services. The real strength of the Optical access network is in its readiness for emerging broadband services such as multimedia and fast internet access and other new and rapidly growing interactive data communication services. It is therefore imperative that the optical fiber access network should be able to support different capacities and mixtures of nan·owband and broadband ports including ATM transport. The access part of the project comprises of several sets of ONUs forming point-to-point or ring stmctures connected to OLTs co-located with the major switching nodes. The OLT represents an interconnection node between the access network and the backbone junction network. It functions as grooming unit for the remote ONUs and splits the Voice, Data, and ATM traffic to the relevant Service Nodes
