Method for optical signal transmission with chromatic dispersion compensation through chirped optical fibre gratings, and optical communication system using the method |
摘要 |
<p>In a communication system with an optical fibre transmission line (3), a compensation of chromatic dispersion due to the fibre (3) is performed through at least one compensation module (4; 4A ... 4N) based on chirped optical fibre gratings having a group delay characteristic @ ( omega ) which exhibits ripples around a nominally linear profile, as a function of the optical signal frequency. To minimise the effect of said ripples, the compensation is carried out in such a way that, for a given fibre length (3), the operating point is located in a limited slope region along the curve representative of system performance degradation owing to chromatic dispersion. <IMAGE></p> |
