Abstract:
An apparatus for transmitting signals over an optical fiber, said apparatus comprising:a plurality of fiber optic sources producing a plurality of wavelengths, a first one of said fiber optic sources producing a first output having a first wavelength and a second one of said plurality of fiber optic sources producing a second output having a second wavelength, wherein the first output wavelength and the second output wavelength has a difference of substantially 2.2 nanometers;a means for modulating the first and second outputs of the fiber optic sources with signals to produce first and second modulated outputs;a means for combining the first and second modulated outputs to produce a wavelength-division-multiplexed output;an optical fiber having a transmitter end and a receiver end, the transmitter end of the optical fiber being adapted to receive the wavelength-division-multiplexed output; andmeans for applying a dither to at least one of the fiber optic transmitters such that the dither reduces crosstalk in the signals of the wavelength division multiplexed output at the receiver end of the optical fiber.
