• W2097958265 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 opti system 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: Computation of Channel Dissipation on Each Breakdown Condition has give the insertion for 16.4 dB (normal condition), 18.8 dB (failure order 1), 21.2 dB (failure order 2) and 23.6 dB (failure order 3). Simulation was carried out to study the maximum distance that can be achieved for signaling path in two situations which are; in normal and breakdown condition with the restoration scheme. The sensitivity that used in analysis to study the maximum fiber length is -25, -30 and -35 dBm. The result shows output power that linearly decrease as the fiber length is increased; for four breakdown condition in this protection network. The highest output power achieved by normal condition at each increase in distance compared to the output power at level 3 breakdown. In addition, the accessibility of maximum distance is dependent on the sensitivity used. In order to achieve a high fiber length of more than 20 km-1 at third level breakdown, the proposed sensitivity should exceed -33 dBm. It is based on output power at third level breakdown that recorded at -32.502 dBm (1490 nm) for orderly placement of this protection network. 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." @default.
