Abstract:
1. A method for transmitting information in an optical communication system, comprising: transmitting an optical information signal at a wavelength over an optical link with a first and a second end; pre-distorting for dispersion the optical information signal proximate the first end of the optical link to introduce an initial dispersion in the optical signal in the amount of at least 1000 picoseconds per nanometer (ps/nm), wherein this initial dispersion causes a widening of optical pulses of the optical signal; amplifying the optical signal in-line on the optical link between a transmitter and a receiver without the use of any in-line dispersion compensating modules; and compensating the optical information signal proximate the second end of the optical link for dispersion, wherein the pre-distortion and the compensation have opposite polarity at the transmitting wavelength and wherein the compensation is in the amount of at least 10,000 ps/nm.
