在光纖系統中傳播的多色光會經歷色散，隨著多色光在光纖中傳輸距離和傳
輸速率的增加，色散會導致光纖系統性能嚴重下降。在本論文中，提出了兩種不
同類型的方法，分別為電和光補償方法，以減輕由於色散引起的系統性能下降。
對於電補償法，SJ Savory 的方法用於設計各種階數的電數位濾波器，9 階、17 階
和 33 階的不同與系統的傳輸速率和光纖長度有關，以補償光纖時域中的色散。
對於光補償方法，採用不同類型的光濾波器，即基於馬克-詹德干涉儀的晶格濾波
器和具有高反射表面的法布立－培若干涉儀，稱為 Gires-Tournois 干涉儀，都是
用於執行色散補償。使用數位濾波器概念，可以在 OptiSystem 中的 Z 轉換中模擬
光濾波器。從仿真結果可以發現，隨著數位濾波器階數的增加，補償效果沒有明
顯變化。另一方面，光濾波器的補償效果顯著，而基於 MZI 的晶格濾波器效果更
為突出。

A polychromatic light wave, propagating in an optic fiber system experiences the
chromatic dispersion. As the transmission traveling distance and the bit rate of the
polychromatic lightwave in the optic fiber increase, chromatic dispersion can cause
serious optic fiber system performance degradation. In this thesis, two different types of
approaches, the electrical and optical ones, have been proposed to mitigate the system
performance degradation due to the chromatic dispersion. For the electrical
approaches, the S. J. Savory 's method is used to design electrical digital filters with
various orders, the 9th, 17th and 33rd orders that are chosen according to the
consideration of different transmission speeds of the system and lengths of optical fibers
to compensate for the chromatic dispersion in the time domain. For the optical
approaches, different kinds of optical filters, viz., the lattice filters based on the MachZehnder Interferometer and Fabry-Pérot interferometer with a highly reflective surface
called Gires-Tournois interferometer are employed to perform the chromatic dispersion
compensation. Using the digital filters concepts, the optical filters can be simulated in
the OptiSystem in the domain of the Z-transform. From the simulation results, it is
found that as the order of the digital filter increases, the compensation effect does not
change significantly. On the other hand, the compensation result of the optical filters is
significant while the effect of the lattice filter based on MZI is more outstanding.
