Title:
OPTICAL DEVICE, RECONFIGURABLE OPTICAL ADD-DROP MULTIPLEXER, AND SIGNAL MONITORING METHOD
Document Type and Number:
WIPO Patent Application WO/2024/027416
Kind Code:
A1
Abstract:
An optical device, a reconfigurable optical add-drop multiplexer, and a signal monitoring method. A first optical switching engine transmits a first WDM signal to a first area in a second optical switching engine by means of a dispersive system at a first moment, and rotates at a second moment such that a second WDM signal is transmitted to a second area in the second optical switching engine by means of the dispersive system. The second optical switching engine can modulate a pattern by means of a fixed optical field, transmit an optical signal of a first wavelength in the first WDM signal from the dispersive system to a photodetector at the first moment, and transmit an optical signal of a second wavelength in the second WDM signal from the dispersive system to the photodetector at the second moment. In this way, the wavelength of an optical signal transmitted to the photodetector can be quickly adjusted by rotating the first optical switching engine, thereby accelerating the speed of WDM signal monitoring.
