Abstract

Since optical fiber amplifiers were developed, the fiber loss does not limit the transmission distance. But there are two effects, the chromatic dispersion and Kerr nonlinearity of the fiber, which limit the distance and the bit-rate of the transmission. In order to avoid these effects and transmit a lightwave over a longer distance, one may use optical solitons in a fiber¹ or convert the lightwave into the phase conjugate wave in the transmission line². These methods, however, require precise adjustments of the transmission parameters.
