Title:
OPTICAL TRANSMISSION APPARATUS AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/089123
Kind Code:
A1
Abstract:
The present invention relates to the technical field of optical communications. Disclosed in embodiments of the present invention are an optical transmission apparatus and system. A first optical transmission apparatus 1 comprises multiple first lasers 11 emitting light having different wavelengths, a first optical circuit device 12, a first modulator 13, and a first processing component 14. The multiple first lasers 11 emitting light having different wavelengths are respectively optically connected to multiple optical input ports of the first optical circuit device 12. The first optical circuit device 12 is used to perform wavelength combination on continuous light having different wavelengths and emitted by the multiple first lasers 11, and to perform power beam splitting to form two beams of continuous light. One beam of continuous light is transmitted to the first modulator 13, and the other beam of continuous light is transmitted to a peer second optical transmission apparatus 2. The first processing component 14 is used to transmit a first analog signal to the first modulator 13. The present invention can lower the requirement on precision of a laser.
