Title:
TRANSMISSION METHOD AND RELATED DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/022028
Kind Code:
A1
Abstract:
Disclosed in the present application are a transmission method and a related device. The transmission method comprises: an optical transmission device generates a first transmission frame, the first transmission frame comprising a first sequence and a second sequence, the first sequence corresponding to a first single-frequency signal and a second single-frequency signal in a frequency domain, the frequency of the first single-frequency signal being fixed in a first time period, the frequency of the second single-frequency signal being fixed in the first time period, the first time period being at least part of the time period when the optical transmission device transmits the first sequence, a difference value between the signal amplitudes of frequency domain signals corresponding to the second sequence in the frequency domain on any two frequencies in a first bandwidth being smaller than a first threshold value, or, the difference value between the signal amplitudes of frequency domain signals corresponding to the second sequence in the frequency domain on any two frequencies except the frequency 0 in the first bandwidth being less than the first threshold value, and the first bandwidth being the bandwidth for the optical transmission device to transmit the first transmission frame; and the optical transmission device transmits to an optical reception device the first transmission frame.
