ABSTRACT Disclosed is an optical fiber transducer system with energy generating means for transmitting pulsing energy at various frequencies to bidirectional couplers for each frequency. The couplers record the intensity and further transmit the pulsing energy to a wavelength multiplexer/demultiplexer. The wavelength multiplexer/demultiplexer combines the plurality of energy supply means into a single output for an optic fiber which includes an optical delay sufficient to time separate the pulsing waves of energy. Reflected energy is transmitted back through the same wavelength multiplexer/demultiplexer, bidirectional coupler so that the recorded intensity of transmission and reflectance are comparable without system influence. A method is also shown for use of an optical fiber system including the components set forth and the system requires the generation and combination of the various frequencies of energy in a multiplexer/demultiplexer, the delay for time separation and the detection in a bidirectional coupler of transmitted and reflected energy.
