APPARATUS FOR ADJUSTING DISPERSION OF OPTICAL SIGNAL

摘要

An apparatus for controlling dispersion of optical signals is provided to variably control or correct color dispersion and polarizing mode dispersion generated in an optical fiber transmission path of a high speed optical transmission system. An apparatus for controlling dispersion of optical signals includes a color dispersion control part(200) and a polarizing conversion part(100). The color dispersion control part indicates different color dispersion control properties about optical signals of two polarizing modes. The polarizing conversion part receives the optical signals inputted from outside, and transmits the optical signals to the color dispersion control part after converting a polarizing state of the optical signals into a polarizing state corresponding to one of the polarizing modes.
