Apparatus and method for reorganizing resources of optical fiber cabinet and optical fiber cabinet

An apparatus for reorganizing resources of an optical fiber cabinet and configured to search for ports located at two ends of a same optical transmission path, wherein the optical fiber cabinet comprises at least two optical transmission paths, each optical transmission path is provided with a first port and a second port, and the apparatus for reorganizing resources of an optical fiber cabinet comprises:

• a macrobending injected-light modulation and control module, configured to modulate an injected optical signal according to a port identifier of a first port, and inject the injected optical signal to an optical fiber connected to the first port;
• multiple macrobending signal detection modules, separately configured to receive received optical signals at second ports of the multiple optical transmission paths;
• a phase-locked detection module, electrically connected to the macrobending injected-light modulation and control module and the multiple macrobending signal detection modules, and configured to receive the received optical signals at the second ports of the multiple optical transmission paths and the injected optical signal, acquire and output a port identifier of a second port that corresponds to a received optical signal consistent with the injected optical signal, and acquire and output a port identifier of the first port;
• and
• a port matching module, configured to receive the port identifiers of the first port and the second port that are output by the phase-locked detection module, and establish a matching correspondence between the first port and the second port according to the port identifiers of the first port and the second port.

A method for reorganizing resources of an optical fiber cabinet, comprising:

• modulating an injected optical signal and injecting the injected optical signal to a first port of an optical transmission path;
• acquiring a received optical signal at a second port of the optical transmission path, and when the injected optical signal is consistent with the received optical signal, outputting detection confirmation information;
• and
• matching the first port with the second port according to the detection confirmation information.
