title: Amplification and reshaping of optical solitons in glass fiber-II.
abstract: Optical solitons can be transmitted through a low-loss fiber to a distance exceeding 6 x 10(3) without a conventional repeater if they are amplified periodically at appropriate distances. An example of a numerical simulation for a 2-gigabit/sec system is presented with solitons having peak power of 11.2 mW, a width of 34.2 psec in a monomode fiber with a cross-sectional area of 20 microm(2), a loss rate of 0.2 dB/km at lambda = 1.5 microm, and amplifiers with 2-dB power gain spaced at every 10 km.
