摘要

Driven by fast growing ultra-broadband applications and the advancement of photonic technology, Next Generation Passive Optical Network (NGPON) is positioned as one of the most promising carriers to enable highspeed backbone networks for mobile cloud services in transportation. Long-reach Passive Optical Network (LRPON) is one of the significant directions for the evolution of NGPON. To establish a low-cost deployment of LRPON and achieve the long-distance optical transmission, cascaded optical amplifiers (OAs) are the key to compensate for the optical signals. In this paper, we propose a novel heuristic algorithm for LRPON infrastructure layout planning which focuses not only on the splitter placement, but also on the power awareness and network availability, to maintain LRPON cost-effective competitiveness and mitigate the impacts of various optical losses by fiber transmission and network equipments with specified network availability. The problem has jointly considered the largest possible area coverage while consisting of equipment cost, optical link degradation factors and network stability in a single optimization framework. The heuristic is called Fast-Backward-Seeking (FBS), which can provide deployment solutions for large sized problems fast and effectively. Numerical scenarios are executed to validate and demonstrate the performance and effectiveness of the proposed heuristic. The results have verified the cost-effective performances of the FBS.
