ABSTRACT:
A fiber optic telephone system is described in which a plurality of subscribers with different bandwidth subscriptions are each connected to the system by an optical fiber subscriber connection. Use of the subscriber connection beyond the subscription bandwidth is prevented by the installation of a bandwidth limiting device having a maximum transmitted bandwidth capacity above that of the subscription bandwidth but below that of the total bandwidth capacity of the subscriber connection.
