OPTICAL FIBRE TELECOMMUNICATION PROCESS, LINK USING SAID PROCESS AND PUMPING SYSTEM FOR A FOUR WAVE MIXTURE, PARTICULARLY FOR SAID LINK

摘要

process for optical fiber telecommunication system applying this method, and pump four wave mixing in particular for binding optical waves (w1)a signal transmitting w2) (s) are guided in a line consisting of optical fibres having a chromatic dispersion.to compensate for the effects of the dispersion is in a line through the phenomenon of four wave mixing in a pumping light is injected into a fiber by emailangel (8). according to the invention, the pumping light is composed of two pump waves (p1, p2). polarization (v1, v2) of these two waves are orthogonal.the optical frequencies. p1,. p2) are substantially symmetrical to one another at a frequency (? a chromatic dispersion of annulling the fiber mixture.the invention applies in particular to the bond lengths. figure 1 is to be published.
