Title:
LIGHT-EMITTING APPARATUS, AND METHOD FOR EMITTING OPTICAL SIGNAL
Document Type and Number:
WIPO Patent Application WO/2024/037219
Kind Code:
A1
Abstract:
Provided in the present application are a light-emitting apparatus and a method for emitting an optical signal. The apparatus comprises: a laser device, which is used for emitting a first optical signal and a second optical signal, the first optical signal being an optical signal which is output by the laser device forwards, the second optical signal being an optical signal which is output by the laser device backwards, and information which is carried in the second optical signal being the same as information which is carried in the first optical signal; a photoelectric detector, which is used for performing photoelectric conversion processing on the second optical signal, so as to obtain a first current signal; a service data unit, which is used for receiving user service data and generating a first digital signal; and a pre-compensation unit, which is used for performing pre-compensation on the first digital signal by using the first current signal, so as to obtain a second digital signal, and performing digital-to-analog conversion processing on the second digital signal to obtain a second current signal, wherein the laser device is further used for emitting a third optical signal by using the second current signal. The apparatus disclosed in the present application enables a signal to be accurately pre-equalized in real time in a quick and adaptive manner.
