Abstract

Provided in an embodiment of the present invention are a passive optical network data communication method, device and system. The method comprises: determining a total bandwidth and an allocated bandwidth of M currentoperation wavelength channels in a passive optical network, M being an integer greater than or equal to two; when the total bandwidth of the M currentoperation wavelength channels is greater than the allocated bandwidth, the OLT determines that n operation wavelength channels need to be closed according to the total bandwidth and the allocated bandwidth of the M currentoperation wavelength channels, n being an integer greater than or equal to 1 and less than or equal to M; switching a load on the n operation wavelength channels to be closed to other operation wavelength channels; closing the n operation wavelength channels. The embodiment of the present invention dynamically saves energy in the passive optical network, thus improving the bandwidth utilization rate of the passive optical network system.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to an energy-saving method, device and system for a passive optical network. Background technique [0002] Passive Optical Network (PON) technology is currently a major broadband access technology. In order to solve the traditional time division multiplexing (Time Division Multiplexing, TDM) PON affected by the TDM mechanism, the bandwidth is usually limited. -Wave Division Multiplexing (Time Wave Division Multiplexing, TWDM) PON system. [0003] The TWDM PON system is a point-to-multipoint communication system, in which multiple wavelength channels are used for data transmission and reception between the optical line terminal (OpticalLine Terminal, OLT) at the central office and the optical network unit (Optical Network Unit, ONU) at the user side , each ONU works on one of the wavelength channels. In the downstream direction, the OLT uses the downstream wa...
