In this embodiment, the management and control system may be implemented by an electronic device (e.g., an electronic device such as a server, a computer, a workstation, etc.) electrically connected to the active WDM device. The management and control system configures wavelength information supported by each port of the active WDM equipment, that is, the active WDM equipment receives configuration information sent by the management and control system, where the configuration information may include a port identifier and wavelength information correspondingly supported.
In an optional embodiment of the invention, the method further comprises: the WDM equipment obtains wavelength information of the optical signal and verifies whether the wavelength information is wavelength information supported by a corresponding port; and when the WDM equipment determines that the wavelength information is not the wavelength information supported by the corresponding port, outputting alarm information corresponding to the port.

Based on the foregoing embodiment, the embodiment of the present invention further provides a management control method for a new forwarding network. Fig. 3 is another schematic flow chart of a management control method of a new forwarding network according to an embodiment of the present invention; as shown in fig. 3, the method includes:
step 201: the service optical module obtains a second optical signal sent by the WDM equipment; the second optical signal is obtained by the WDM equipment performing optical splitting processing on the first optical signal; the first optical signal and the second optical signal are both multi-wavelength optical signals;
step 202: and the business optical module carries out filtering processing on the second optical signal to obtain a target optical signal.
In this embodiment, the service optical module is composed of an optoelectronic device, a functional circuit, an optical interface, and the like, and the optoelectronic device may include a transmitting end and a receiving end. The service optical module is used for photoelectric conversion, for example, a transmitting end converts an electrical signal into an optical signal so as to transmit the optical signal through an optical fiber; the receiving end may convert the optical signal into an electrical signal.
In an optional embodiment of the present invention, the performing, by the service optical module, filtering and analyzing the second optical signal to obtain the target optical signal includes: and the service optical module performs filtering analysis processing on the second optical signal according to the preconfigured wavelength information to obtain a target optical signal matched with the wavelength information.
In this embodiment, the service optical module may pre-configure or factory-set wavelength information, that is, the service optical module only processes an optical signal corresponding to the pre-configured or factory-set wavelength information. The service optical module performs filtering analysis processing on the second optical signal according to the preconfigured wavelength information, and the wavelength of the obtained target optical signal is the preconfigured wavelength.
The connection modes of the forwarding network in the related art mainly include the following three types: fiber direct drive, passive wavelength division schemes, and active wavelength division schemes. The optical fiber direct drive mode can consume a large amount of forward transmission optical fiber resources, and is used for bearing 5G sites, and at least 12 optical fibers are consumed, so that a large amount of optical fiber resources need to be newly added to a forward transmission network, but the resources are difficult to obtain. The passive wavelength division scheme reduces the use of optical fibers by adding passive wavelength division transmission devices between the AAU and the DU, but the passive devices cannot manage the forwarding network. The active wavelength division scheme is that active wavelength division equipment is added on the AAU side and the DU side respectively, the wavelength of multiple paths of forward transmission optical fibers is multiplexed to a single optical fiber, the reduction of the optical fiber resource consumption is realized, and the monitoring and the protection of a forward transmission optical fiber link are realized on the active wavelength division equipment. The active wavelength division equipment can well control and protect a forwarding network, but both the AAU and the DU need to be connected into the active wavelength division equipment, and the active wavelength division equipment needs to be additionally powered, so that the equipment room has higher power requirement, and the cost for increasing the active wavelength division equipment is higher.
By adopting the technical scheme of the embodiment of the invention, the multiplexed first optical signal is divided into a plurality of second optical signals with multiple wavelengths through the light splitting processing of the WDM equipment, the service optical modules obtain the target optical signal through the filtering processing, and the optical channel matching communication between the service optical modules at two communication ends is realized, so that the service intercommunication of the fronthaul network is realized, the mixed insertion of ports with different wavelengths can be realized, the binding of the ports and the wavelengths is released, the more flexible configuration is supported, and the maintenance and the control of the fronthaul network are facilitated. In addition, only by accessing the active WDM equipment at the DU side, compared with the case that both the AAU and the DU access the active wavelength division equipment, the power consumption and the equipment cost are greatly reduced.
