Using the Pre-Chirp Method for Compensation of the Dispersion Effect on Optical Fibers

Scattering is one of the main factors limiting the amount of information that can be sent and the distance sent to a fiber. In fact, after attenuation, the most important factor limiting the transmission of optical information is scattering. In this paper, after reviewing the electronic solutions of scattering compensation methods, the pre-grease method for scattering compensation in optical fibers has been introduced. In fact, this method is one of the pre-compensation methods. In this method, before applying the pulse to the fiber, its properties are modified in such a way that the propagation due to "group velocity scattering" is minimized, which is called applying grease to the input pulse. The results show that the use of such fibers for short distance compensation compensates for parameters such as factor Λ and FBG .
