Abstract

Problem statement: This study highlight on restoration scheme proposed against failure in working line at the drop region for Fiber-To-The Home (FTTH) with a Passive Optical Network (PON). Whereas PON is a system that brings optical fiber cable and signals all or most of the way to the end user. In this study we highlighted the issue on survivability scheme against failure which is focused scattered residence architectures. Approach: Two type of restoration scheme is proposed by means of linear protection (tree) and migrate protection (ring). Our proposal scheme is inexpensive and applicable to any residence architecture (ordered placement and scattered placement). The advantage of this scheme is the failure at fiber line can be recovered until two levels to make sure the optic signal flow continuously. FTTH based network design is simulated by using OptiSystem 7.0 in order to investigate the power output and BER performance at each node in the tree and ring protection scheme in scattered placement to prove the system feasibility. Results: The simulation analysis for output power in a linear protection path produced almost same output power for all optical nodes regardless of the position and situation of the node. In linear protection, signal is split by optical splitter and did not having loss of power at each node. Thus the percentage adjustment on the coupling is obtained where; the average output power measured at the receiver is at -28.4206 dBm. While the signal for ring path is optimized by adjusting the loss ratio (n%) and transmit it (1-n%) in the optical coupler. Also found that; an average output power is -23 dBm only. A simulation of distance accessibility is increased with the increasing of sensitivity that used for the linear path and ring path. Conclusion: This study suggests the migration of tree to ring topology to enable the signal flow continuously in the case of failure occurs specifically in random or scattered placement topology. Our proposal is the first reported up to this time in which the upstream signal flows in anticlockwise in ring topology when the restoration scheme activated.
