Title:
OPTICAL SIGNAL PROCESSING METHOD AND OPTICAL CROSS-CONNECT DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/088724
Kind Code:
A1
Abstract:
The embodiments of the invention disclose an optical signal processing method and optical cross-connect device. The method comprises: an input terminal i of an optical cross-connect device first receives a first optical signal; a transmitter signal processing module i performs, based on the first optical signal, first phase modulation and first frequency modulation to obtain a THz signal containing signal information of the first optical signal; a transmitter antenna i transmits the THz signal; a receiver antenna j receives the THz signal; a receiver signal processing module j performs, based on the THz signal, second phase modulation and second frequency modulation to obtain a second optical signal containing the signal information; and an output terminal j outputs the second optical signal. Implementing the embodiments of the invention can increase a switching speed of an optical cross-connect device, decrease device costs, increase device integration, and expand a scale.
