In this embodiment, when the first WDM apparatus determines that the wavelength information and the wavelength configuration information of the first port and the corresponding second port are both matched and consistent, the optical channel communication between the first port and the corresponding second port is controlled.
The connection mode of the forwarding network in the related technology mainly includes 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 active wavelength division scheme is that active wavelength division equipment is added on the AAU side and the DU side respectively, the wavelength of a plurality of paths of forward transmission optical fibers is multiplexed on a single optical fiber, the reduction of the consumption of optical fiber resources 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 wavelength corresponding to the port of the first WDM equipment is configured through the management and control system, and the wavelength information of the service optical module is matched with the wavelength configuration information of the corresponding port, so that the matching result is obtained and output, the operation and maintenance personnel can quickly acquire the installation state of the service optical module corresponding to the port, the operation and maintenance personnel can conveniently install and debug the service optical module, and the service intercommunication of the fronthaul network is realized. In addition, only by accessing the first WDM equipment (active WDM equipment) at the DU side, compared with the case that both AAU and DU access the active wavelength division equipment, the power consumption and the equipment cost are greatly reduced.
