The present invention relates to the field of optical processing technologies, and discloses a method and an apparatus for acquiring an internal fiber connection relationship in a reconfigurable optical add/drop multiplexer, which may accurately and efficiently acquire an internal fiber connection relationship in a reconfigurable optical add/drop multiplexer. The present invention includes: acquiring logic optical propagation paths between an egress port of a wavelength selective switch at a receive end and an ingress port of a wavelength selective switch at a transmit end; separately configuring a different wavelength cross connection for the acquired logic optical propagation paths; connecting a communication light source to an ingress port of the wavelength selective switch at the receive end; collecting a wavelength of an optical signal on an egress port of the wavelength selective switch at the transmit end; determining, according to the collected wavelength of the optical signal, a logic optical propagation path corresponding to the collected wavelength of optical signal; and determining a fiber connection relationship between the egress port of the wavelength selective switch at the receive end and the ingress port of the wavelength selective switch at the transmit end according to the logic optical propagation path corresponding to the collected wavelength of optical signal, and storing the fiber connection relationship. Embodiments of the present invention are mainly used in a process of acquiring an internal fiber connection relationship in a reconfigurable optical add/drop multiplexer. |
