Abstract
A fiber optic communication system provides parallel paths to enable cancellation of even order harmonic distortion components. A pair of parallel optical fibers is provided. Each of the fibers is coupled to a corresponding transmitter at one end of the pair and to a corresponding receiver at the other end of the pair. The transmitters are modulated with an input signal applied to the transmitters at a 180.degree. phase differential. The 180.degree. phase shifted signals are combined at the receivers to recover the input signal while cancelling even order distortion products introduced by the transmitters. A method is provided for balancing the system upon installation.
