Title:
OPTICAL TRANSMISSION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/029006
Kind Code:
A1
Abstract:
In the present invention, an optical filter is configured to selectively pass, as output light, at least one wavelength component among a plurality of wavelength components included in input light. The optical filter is provided with a movable element. In the present invention, a controller is configured to adjust a passband by controlling the movable element on the basis of power of light corresponding to the output light measured by a power monitor. The optical filter is configured such that a gain curve corresponds to a convex function having a peak at the center wavelength of the passband in a first wavelength band including the center wavelength, and the gain curve exhibits inclination steeper than the convex function in a second wavelength band adjacent to the first wavelength band.
