A Single Optical Fiber Telephone System
Abstract
A hybrid telephone system comprising a plurality of optical telephones and a plurality of electrical telephones all connected to a conventional central office. The optical telephones are all provided with opto- electrical interface units co-located with the central office, for converting optical signals received from the optical telephones to electrical telephone signals, and for converting electrical telephone signals from said central office to optical signals for transmission to the optical telephones. The optical telephones are connected to the interface units by means of a single optical fiber which carries both directions of traffic as well as supervisory signals at one of two wavelengths. The optical telephone include means for separating these two wavelengths as well as opto-acoustic and acousto-optic converters.
