Abstract

The prospects for fiber to the subscriber residence continue to be unsettled. It Is clear that at today's component costs, the price of an all-fiber system exceeds a reasonable Investment for residential subscriber services. Relying only on learning curve effects, it is possible to anticipate that the costs for new fiber systems can approach that of a combined new twisted wire and coaxial system. However, such costs are too high to open up the retrofit market. This constricts fiber deployment to situations where new housing is being constructed or to cases where the embedded base has been completely written off. Necessary strategies are discussed to reach lower cost levels.
