British Telecom TPON application in the US network

The authors discuss the cost modeling against copper of various forms of TPON (telephony over a passive optical network) in a typical US environment. Passive optical networks such as TPON, with their lean use of fiber and low-fixed costs, are shown to be less sensitive to distance than copper. This leads to he conclusion that the approach can be a cost-effective method of delivering POTS while providing an effective platform for future wideband or broadband upgrades. Although TPON has been used as a role model for this costing, several approaches should be capable of similar results
