Abstract—This paper considers the cost of deploying a FTTH access network with varying number and lo-cation of supply points (POPs). A center of gravity optimization is used to compare the use of Euclidean distance and road distance along with a third combina-tion of the two. Optimization is performed on the total line distance to the demand points (NTs). Initial loca-tions are considered along with reduction in complexity. The results prove the combination method, that uses the optimized location from the Euclidean optimization as initial locations for the road optimization, to be the best. Substantial savings are achieved compared to lo-cations in the existing copper network.
