APPARATUS AND METHOD FOR OPTICAL SPLITTER PORT RECOGNITION, AND METHOD AND APPARATUS FOR OPTICAL SPLITTER TEMPERATURE DETECTION

摘要

An optical splitter and a system comprise an optical branching device, a band fiber, and a branch optical fiber. The optical branching device is used for dividing an input optical signal into at least two paths of optical signals for outputting. One end of the band fiber is connected to the optical branching device, and the other end of the band fiber is connected to the branch optical fiber. The band fiber is provided with a grating array, the grating array comprises at least two Bragg gratings, different Bragg gratings are corresponding to different branch lines of the optical branching device, and the number of the Bragg gratings comprised in the grating array is equal to the number of the paths of optical signals outputted by the optical branching device. The problem of increasing additional connection loss because an existing optical splitter needs to be connected to optical fibers of each link through optical connectors is solved, thereby reducing connection loss of devices.
