Abstract:
A method of minimizing dispersive radiation in an optical fiber transmission system utilizing solitons and having at least a first and second type of optical fibers and an amplifier comprising the steps of:1.) determining a first optimal length of said first type optical fiber to form a first length of optical fiber; 2.) determining a second optimal length of said second type optical fiber to form a second length of optical fiber, 3.) connecting the optimal lengths of said first and second type of optical fibers to form a first dispersion map; 4.) locating an amplifier after every said dispersion map; 5.) locating points in the dispersion map connected to the amplifier where the pulse chirp is zero; 6.) said first and second optimal lengths being those lengths where the net amount of chirp accumulated before and the net amount of chirp accumulated after said zero chirp point balance one another for all wavelengths; 7.) repeating steps 3 and 4 to form a plurality of dispersion maps and amplifiers in a transmission line; and, 8.) cutting the first dispersion map in said transmission line at said zero chirp point to create an optimal launch point for all wavelengths in said transmission line.
