Method for detecting coupling of optical module and optical fibers

Abstract

The invention discloses a method for detecting coupling of an optical module and optical fibers. The technical problem that a detection mode for coupling of the optical module and the optical fibers is low in efficiency is solved. The method includes the steps that the space positions of N paths of optical lens arrays are adjusted; the optical powers of N paths of optical signals output by the N paths of single-mode optical fibers are acquired from the output end of an optical power meter; the optical powers of the N paths of optical signals are displayed as N histograms with the first resolution, and the optical powers and the heights of the histograms are in a direct proportion relation; the space positions of the N paths of optical lens arrays are adjusted based on the states of the N histograms, and then the top ends of the N histograms are located between a first marked line and a second marked line; the first marked line and the second marked line are graphical display for the allowed minimal power value and the allowed maximal power value, and when the top ends, corresponding to the histograms, of the N paths of optical signals are located between the first marked line and the second marked line, the coupling degree of the optical module and the optical fibers is optimal. Complex manual recording and comparison steps are omitted in a visual mode, and detection efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of optical communication, in particular to a coupling detection method for an optical module and an optical fiber. Background technique [0002] In the existing optical communication technology, the optical signal is used as the carrier of information, which can transmit information at high speed, long time and reliably; while the optical module is the core component in the field of optical communication technology, the coupling between its optical element and the optical fiber as the transmission path The effect directly affects the intensity of the output optical signal and the quality of the optical signal, so the coupling effect between the optical module and the optical fiber becomes a key factor affecting information transmission. [0003] In order to make the connection between the optical module and the optical fiber have an optimal coupling degree, before the optical module leaves the factory, it is...
