Abstract
Pulses of electromagnetic energy of appropriate peak power can form soliton pulses in monomode fiber. The width of such pulses changes during propagation, and can decrease for certain ranges of peak power, e.g., between about P.sub.o and 9/4 P.sub.o, where P.sub.o is the 'balanced' peak power. Using this property, repeaterless transmission of soliton pulses is possible if the pulses are non-electronically amplified by appropriate amounts at appropriate intervals. Exemplary amplifying means are glass laser, Raman laser, semiconductor laser medium, and cw injection.
