DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application.

[0019] A passive optical network (PON) is a point-to-multipoint passive optical network, including an OLT located at a local end, an ONU / FTTR and an ODN. The OLT is responsible for connecting with a metropolitan area network or a wide area network, and managing a plurality of ONUs and signals thereof. The ONU / FTTR is a terminal device, and provides signals transmitted by the OLT to a user for use. Transmission from the ONU / FTTR to the OLT is in an uplink direction, and signals are transmitted in a time-division multiplexing manner using one wavelength. Transmission from the OLT to the ONU / FTTR is in a downlink direction, and signals are transmitted in a broadcast manner using another wavelength different from the uplink direction.

[0020] The ODN is composed of an optical fiber, a 1:N optical splitter and other passive optical devices, and the related art connects the OLT and the ONU / FTTR by using a two-stage 1:8 optical splitter, from the OLT side to the ONU side, which is the OLT, a first-stage optical splitter, a second-stage optical splitter and the ONU / FTTR. Since the optical splitter is a passive device, the ODN network state is unknown, that is, it is impossible to know which port of the first-stage and second-stage optical splitters a certain ONU is connected to, and thus it is impossible to realize PON resource management, line fault detection and topology restoration.

[0021] In view of the defects of the related art, the embodiment of the present application provides a resource management method of an optical distribution network, which can realize PON network line resource management. In order to describe the technical solutions of the present application, the following will be described by specific embodiments.

[0022] Figure 1 is a flowchart of an implementation process of a resource management method of an optical distribution network provided by the embodiment of the present application, and the execution subject of the resource management method of the optical distribution network is an optical network unit, which can be an ONU or an FTTR. Referring to Figure 1 , the resource management method of the optical distribution network comprises: S101, carrying service signals and management signals in two wavelengths of the same optical fiber respectively.

[0023] The embodiment provides a new light emitting mechanism of an optical network unit. In the uplink direction, two wavelengths in one optical fiber are used in the transmission process from the optical network unit to the OLT, for example, a service wavelength and a management wavelength, which carry service signals and management signals respectively. The service wavelength is a wavelength used for transmitting service signals in the PON, which is used to transmit real service information of users. The management wavelength is used for transmitting management signals, and the management signals can be a uniformly distributed random sequence with only 0 and 1. In the downlink direction, one wavelength in one optical fiber is still used in the transmission process from the OLT to the ONU / FTTR. The center wavelengths of the uplink service wavelength and the uplink management wavelength are different from the downlink wavelength.

[0024] S102, transmitting the service signals and the management signals to an optical splitter through the same optical fiber, and modulating the management signals according to a preset modulation mode corresponding to a port receiving the service signals and the management signals by the optical splitter; wherein each port of the optical splitter corresponds to a different preset modulation mode.

[0025] The service signals and the management signals are transmitted to the optical splitter through the same optical fiber. The optical splitter has one port on the combining side and multiple ports on the splitting side. The multiple ports on the splitting side receive the service signals and the management signals transmitted by the optical network unit.

[0026] The optical splitter uniquely modulates the management signal received by each port. Each port of the optical splitter corresponds to a different preset modulation mode, and the management signal is modulated according to the preset modulation mode corresponding to the port receiving the management signal.

[0027] In the method, the management signal is modulated, that is, the management signal is changed, and the changed information corresponds to the ports one by one, and the changed information is one or more of the phase, frequency and amplitude of the management signal.

[0028] The related technical solution cannot obtain the specific connection condition of the ODN network because the splitter does not distinguish the port information, and cannot accurately perform network operation and maintenance on the optical access network line. The embodiment of the application can accurately obtain the port information of each ONU at the splitter, can restore the access network topology, and is helpful for access network operation and maintenance.

In the uplink direction, the service wavelength processing module transparently transmits the signal without any change, and the management wavelength processing module changes the management signal. In the downlink direction, the downlink direction processing module transparently transmits the signal without any change.

[0033] In the uplink direction, each port of the optical splitter can perform different operations on the service wavelength and the management wavelength respectively, for example, transparently transmitting the service signal of the service wavelength without any change, and changing the management signal of the management wavelength, the changed information corresponding to the port one by one, and the changed information being one or more of the phase, frequency and amplitude of the management signal. In the downlink direction, each port of the optical splitter transparently transmits the service information of the service wavelength without any change.

[0034] The different modulation indexes and modulation parameters (one or more of the phase, frequency and amplitude) can be set for each port in advance, and the port modulates the management signal by using the corresponding modulation index and modulation parameter after receiving the management signal. The resource processing device demodulates the received modulated management signal, determines the modulation index and modulation parameter used thereby, and thus determines the corresponding optical splitter port.

[0040] The resource processing device analyzes the modulated management signal, determines the modulation mode used thereby, and thus can determine the corresponding port, so as to obtain the correspondence between the optical network unit and the optical splitter port.

[0041] The optical distribution network device receives the service signal and the management signal transmitted by the optical network unit through the same optical fiber, the center wavelengths of the service signal and the management signal are different, the management signal is modulated according to the preset modulation mode corresponding to the port receiving the service signal and the management signal, and each port of the optical distribution network device corresponds to a different preset modulation mode.

[0042] In an embodiment, the modulating the management signal comprises: Modulating one or more of the phase, the frequency and the amplitude of the management signal.

[0043] Different modulation indexes and modulation parameters (one or more of the phase, the frequency and the amplitude) can be set for each port in advance, and the management signal is modulated by using the corresponding modulation index and modulation parameter after the port receives the management signal.

[0044] For example, different transmission delays can be set for each port of the optical distribution network device in advance, and the management signal is transmitted by using the transmission delay corresponding to the port.

[0045] In an embodiment, the service signal comprises an identifier of the optical network unit, or the management signal comprises the identifier of the optical network unit.

[0046] In order to enable the resource processing device to determine the port mapping relationship, the identifier of the optical network unit needs to be added to the service signal and / or the management signal, and the resource processing device can map the identifier of the optical network unit to the port of the optical distribution network device.
