ABSTRACT:
A fiber-optic transmission system includes a transmitter having a designed chirp value. The transmitter has first and second inputs for receiving first and second input signals, respectively, used to produce a modulated output signal. An optical fiber is responsive to the transmitter for receiving the output signal. A circuit asymmetrically drives the first and second input signals so as to change the designed chirp value of the transmitter to another value. Methods of controlling the chirp of a commercially available transmitters are also disclosed. Because of the rules governing abstracts, this abstract should not be used to construe the claims.
