Title:
OPTICAL EQUALIZER AND OPTICAL SIGNAL PROCESSING METHOD
Document Type and Number:
WIPO Patent Application WO/2023/155057
Kind Code:
A1
Abstract:
The present application provides an optical equalizer and an optical signal processing method, which can meet the requirement of flexibly setting coefficients in practical application. The optical equalizer of the present application comprises: a control module, an adjustment module, an optical switch, a first conversion module, and a second conversion module, wherein the control module may send a first control signal to the adjustment module and send a second control signal to the optical switch; after receiving an optical signal and the first control signal, the adjustment module may adjust the intensity of the optical signal on the basis of the first control signal; after receiving the adjusted optical signal and the second control signal, the optical switch may send the adjusted optical signal to the first conversion module or the second conversion module on the basis of the second control signal; and if the first conversion module has received the adjusted optical signal, the first conversion module converts the adjusted optical signal into a first electrical signal, and if the second conversion module receives the adjusted optical signal, the second conversion module converts the adjusted optical signal into a second electrical signal, wherein the second electrical signal and the first electrical signal have opposite polarities.
