Title:
PROTECTION SWITCHING METHODS AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/005873
Kind Code:
A1
Abstract:
Protection switching methods, an electronic device and a storage medium, a method comprising: a source OTU sends a first wavelength optical signal to a sink OTU by passing through a first working channel (S110); a first input end of a sink OP receives first power of the first wavelength optical signal (S120); and when the first power satisfies a switching trigger condition, the sink OP performs a first switching operation (S130), transmits first APS/PCC signaling to a source OP by means of an optical layer overhead (S140), and enables the source OP to perform a second switching operation according to the first APS/PCC signaling (S150), so as to implement bidirectional switching.
