Computational Analysis of Optimal Splitter Coordinates for Passive Optical Network (PON) Deployment

摘要

Passive Optical Networks (PONs) is seen as a potential backhaul for 4G (LTE) mobile networks because of its excellent technical attributes like capacity, reliability, range and lots more. Determination of optimal location for its splitter is important because of its role in getting total fibre length required for PON network deployment. This paper presents computational techniques for determination of optimal splitter coordinates for Passive Optical Networks. SMILE Mobile Networks Port Harcourt was used as a case study. Cell finder tool was used to obtain the coordinates of all SMILE eNB locations in Port Harcourt. Two methods (Manual and Systematic) were developed. In manual method, 35 sample test splitter locations were considered via the aid of GPS Visualizer tool and the coordinate 4.8277864~0N, 7.026582~0E was obtained as optimal splitter coordinate. Systematic approach utilises Vincenty formula for coordinates, the equations generated were modelled in MATLAB simulation environment to get optimal splitter location with coordinates 4.8276~0N, 7.0254~0E. The results obtained from both approaches were compared and they presented very close similarities, hence produced minimal length of optical fibre for passive optical network deployment.
