Title:
SYSTEMS AND METHODS FOR FAST WAVELENGTH SELECTION IN AN OPTICAL NETWORK
Document Type and Number:
WIPO Patent Application WO/2022/083056
Kind Code:
A1
Abstract:
Systems and methods are described in an optical network. A system includes a first wavelength selector system having a first input port and a first output port, the first input port configured to receive a first set of multi-wavelength signals and the first output port configured to output a second set of multi-wavelength signals, the second set of multi-wavelength signals being a subset of the first set of multi-wavelength signals; a second wavelength selector system having a second input port and a second output port, the second input port configured to receive the second set of multi-wavelength signals and the second output port configured to output a final optical signal from the second set of multi-wavelength signals; and a controller coupled to the first wavelength selector system and the second wavelength selector system.
