Title:
BURST OPTICAL SIGNAL TRANSMISSION METHOD AND RELATED DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/078103
Kind Code:
A1
Abstract:
The present application provides a burst optical signal transmission method and a related device. In the method, a first optical module determines a first sub-bands and b second sub-bands from an uplink system spectrum, reserves a low-frequency first sub-band as a blank sub-band (i.e., not carrying an uplink signal frame), and uses a high-frequency second sub-band for bearing an uplink signal frame. Because the first optical module enables the uplink signal frame to be only carried on the high-frequency second sub-band and does not enable the uplink signal frame to be carried on the low-frequency first sub-band, in a burst receiving process, distortion generated on the low-frequency first sub-band does not affect demodulation of a second optical module on the uplink signal frame carried on the high-frequency second sub-band. Therefore, in the case of using a same receiving device, the preamble overhead of a burst receiving process can be shortened, and the data transmission efficiency can be improved.
