All of the ports are mutually arranged in a staggered manner, the adapters mounted on all of the ports are mutually arranged in a staggered manner, and the optical fiber connectors mounted on all of the adapters are mutually arranged in a staggered manner, so that at least a first photographing direction is present, and the first identification area on the optical fiber connector or the first identification area on the optical cable can be photographed in the first photographing direction. The optical network device can help an engineering person to take a photograph to obtain an on-site image, so that a correspondence between each port identifier and an identification number of a corresponding optical fiber connector can be automatically obtained based on the on-site image. In this case, the on-site engineering person does not need to manually record a correspondence between each optical cable port and an optical cable during construction, but only needs to directly take a photograph along the first photographing direction. In this way, labor costs are low, and construction efficiency and accuracy are high.
