Embodiment Construction

[0041] The basic idea of ​​the present invention is: after receiving the ONU identification information and wavelength information sent by the OLT, the ONU specified by the ONU identification information sets its own working wavelength as the assigned working wavelength according to the wavelength information, and the ONU maintains the current working state, or the ONU Transition to wavelength tuning state, or ONU transition to ranging state.

[0042] The implementation of the technical solution will be further described in detail below in conjunction with the accompanying drawings.

[0043] The present invention mainly comprises the following contents:

[0044] A method for registering and activating an optical network unit. In the stage of ONU registration and activation, the OLT will send the ONU identification information and wavelength information assigned to the ONU to the ONU. After receiving the above message, the ONU will set its own working wavelength as the assigned...

Abstract

The invention discloses a method for registration and activation of an optical network unit. The method comprises: an optical line terminal (OLT) sends optical network unit (ONU) identification information and wavelength information allocated to an ONU to the ONU. The invention also discloses a system for registration and activation of an optical network unit, wherein an OLT is used to send ONU identification information and wavelength information allocated to an ONU to the ONU. The invention also discloses a device for registration and activation of an optical network unit. The device sets its operating wavelength equal to an allocated operating wavelength according to the wavelength information, and keeps the current operating state, or transits to a wavelength tuning state, or an ONU transits to a range finding state. The method, the system and the device can solve the problem that operating wavelength adjustment during ONU registration and activation causes state transition so that time spent on registration is increased.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method, system and equipment for registering and activating an optical network unit in a passive optical network system. Background technique [0002] With the development of network technology, the network can be used to transmit a large number of voice, data, video and other services, so the requirements for bandwidth continue to increase, and the passive optical network (PON) is produced under this demand. [0003] The topology of the PON system is as follows figure 1 As shown, the PON system usually consists of an optical line terminal (OLT) at the office side, an optical network unit (ONU) at the user side, and an optical distribution network (ODN), and usually adopts a point-to-multipoint network structure. ODN is composed of passive optical components such as single-mode optical fibers, optical splitters, and optical connectors, and provides optical transmission ...
