clustering algorithm, we further
consider the opportunity of feeder fiber conduit sharing. In this regard, for each of the K clusters found in step 2 in
which there can be multiple splitters, we keep on applying Weiszfeld algorithm to decide the location for the far end
location of a cable conduit from the CO given the locations of optical splitters and the CO. Specifically, we need to
minimize the sum of the length of the shared conduit and the distances from the conduit far end to each of the
splitters so as to minimize the cost of trenching and laying feeder fibers.
