Background
The optical fiber transmission is data and signal transmission which is carried out by taking the optical fiber as a medium and has the characteristics of high transmission rate, long distance and the like. Mainly based on the total reflection principle of light, the transmission loss characteristic of the optical fiber is one of the most important factors for determining the transmission distance, transmission stability and reliability of the optical network. The causes of transmission loss in optical fibers are manifold, and in the construction and maintenance of optical fiber communication networks, the most significant concern is the cause of transmission loss in use of optical fibers and how to reduce these losses. The transmission loss caused by the use of the optical fiber mainly includes two types of connection loss (inherent loss of the optical fiber, fusion loss and movable joint loss) and non-connection loss (bending loss and loss caused by other construction factors and application environments). When such losses occur, if the light leakage point of the optical fiber can be intuitively positioned, the problem of excessive transmission loss can be quickly solved.
Conventionally, a red light pen is adopted to test the on-off of optical fibers, and the patent provides a method for detecting and analyzing the uniformity distribution of light leakage of the optical fibers and light outlet light pipes by adopting a short wave infrared-visible light converter and combining an optical lens.
