Abstract

The applicability of fiber to the distribution point strategy is investigated for three types of network models and two phases of penetration. The relatively expensive fiber-optic transmission line is shared among multiple subscribers down to a distribution point and then inexpensive metallic lines are used to deliver 50~150 Mb/s pulse streams to respective subscribers. Numerical examples reveal that cost reduction of around 20% and 80% can be attained with small- and large-scale networks, respectively. Sensitivity of the total system cost to fiber and transmitter-receiver costs is analyzed. The results of investigations of upgrading strategies for broadband ISDN deployment are also described
