Title:
WAVELENGTH DISPERSION COMPENSATION MODULE AND OPTICAL TRANSMISSION SYSTEM INCLUDING THE SAME
Document Type and Number:
WIPO Patent Application WO/2001/058057
Kind Code:
A1
Abstract:
A wavelength dispersion compensation module for realizing high bit-rate signal transmission through simple arrangement and an optical transmission system including it. The wavelength dispersion compensation module comprises a wavelength dispersion compensator for compensating the wavelength dispersion of an optical fiber transmission line at a predetermined wavelength, and a temperature regulator for setting a desired wavelength dispersion value of the wavelength dispersion compensator by regulating the temperature thereof. With this arrangement, dispersion compensation control depending on variation in the wavelength dispersion of the optical fiber transmission line with temperature variation can be realized and accumulated wavelength dispersion over the entire optical fiber transmission line can be reduced effectively through a simple arrangement.
