Abstract

A failure in access networks can cause serious problem, becaus e access network transmit aggregated high-speed traffic from hundreds of subscribers. Therefore, Ethernet Passive Optical Network (EPON) was proposed to overcome the bandwidth bottleneck at the Access Network due to its simplicity and cost effectiveness. In this paper, protection is provided to development of survivability scheme for Tree-Based EPON-FTTH architecture. It describes also the advanced customer access network through the development of an Access Control System (ACS). The A CS provides survivability through the Optical Cross Add and Drop Multiplexing (OXADM) against failure by means of dedicated and shared protection that is applied in EPON-FTTH. Each OXADM has a node controller which receives reports on the status periodically from access control system (ACS). When a failure is detected, the ACS will send a command to the related OXADM to be activated. The special function of OXADM; accumulation and 'U' turn mechanism play a important role in switching the traffic to the traffic free alternative path. The survivability of EPON is necessary to provide seamless services and ensure network reliability. We highlighted in this paper the analytical modeling on cascaded OXADM in FTTH using point-to-point configuration according to the number of operating wavelength and number of ports. Finally we come out with comparison result between simulation and analytical to prove the measurement validness.
