The invention discloses an optical fiber identification system and method based on optical fiber cross section combined wavelength. The system comprises a light source module which comprises a driverwhich consists of a light source, a first high-speed SOA optical switch, and a second high-speed SOA optical switch; a circulator and a waveform detector; a main controller which is electrically connected with the driver, the first high-speed SOA optical switch, the second high-speed SOA optical switch and the waveform detector. The main controller is used for controlling the on-off of the first high-speed SOA optical switch and the on-off pulse time T of the second high-speed SOA optical switch so as to determine the length of an optical fiber section of the optical fiber to be tested, and controlling the opening time sequence difference between the first high-speed SOA optical switch and the second high-speed SOA optical switch to determine the starting point distance L of the tested optical fiber section. The difference and characteristics of the backward reflection light wave spectrum of each section of optical fiber can be accurately identified via the waveform detector by utilizing the difference of the molecular structure arrangement of each section of optical fiber microscopically.
Description
technical field [0001] The invention relates to the field of optical fiber communication, in particular to an optical fiber identification system and method based on optical fiber section combined wavelength. Background technique [0002] In the field of optical fiber communication, it is generally believed that the optical characteristics of different positions on an optical fiber are consistent, but that only exists at the macro level. With the advancement of technology, it is required to be able to accurately grasp the characteristics of each fiber segment on the optical fiber. Currently, there is a lack of There are technical solutions that can accurately identify each fiber segment. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, the present invention proposes an optical fiber identification system based on the combined wavelength of the optical fiber section, wh...
