Title:
METHOD, DEVICE AND SYSTEM FOR PROCESSING PASSIVE OPTICAL NETWORK SIGNAL
Document Type and Number:
WIPO Patent Application WO/2019/233177
Kind Code:
A1
Abstract:
Disclosed in embodiments of the present application are a method, device and system for enabling and disabling a wavelength channel pre-coding function of a passive optical network, wherein a plurality of downlink wavelength channels and a plurality of uplink wavelength channels are comprised between an optical line terminal and an optional network unit. The method comprises: an optical line terminal generates an instruction message and issues the instruction message to the optical network unit, the instruction message carrying wavelength information of at least one wavelength and instruction information about whether a signal to be received on a downlink wavelength channel corresponding to the at least one wavelength is decoded by the optical network unit; if the instruction information instructs the optical network unit to decode, pre-code a signal to be sent on the downlink wavelength channel corresponding to the at least one wavelength is pre-coded; if the instruction information instructs the optical network unit not to decode, not pre-code the signal to be sent on the downlink wavelength channel corresponding to the at least one wavelength. In the embodiments of the present application, the pre-coding function of each wavelength channel between the optical line terminal and the optical network unit can be enabled and disabled at any time.
