Abstract:
Provided by the embodiments of the present invention are a remote optical fiber dispersion compensation device and method, the dispersion compensation device comprising: a distance measurement module, used for measuring a remote distance to a remote access optical fiber; a channel monitoring module, used for monitoring the spectral power of a transmission service wavelength channel; and a remote optical fiber dispersion power equalization module, used for compensating the dispersion of a transmission service signal and adjusting the insertion loss of the wavelength channel according to the measured remote distance of the remote access optical fiber and the monitored spectral power of the transmission service wavelength channel. By employing the embodiments of the present invention, compensation amounts of different channels may be flexibly selected by means of a wavelength selection switch, dispersion may be compensated for remote optical fiber transmission and the insertion loss may be adjusted for different channels by presetting dispersion compensation optical fibers of different lengths, thus achieving compensation and equalization of dispersion and power difference introduced by remote optical fibers of different lengths.
