Description
Technical Field
The invention relates to the field of optical fiber equipment, in particular to an optical fiber test crimping connection device and a use method thereof.
Background
An optical fiber, called optical fiber for short, as a light transmission tool, is a fiber made of plastic or glass fiber through a special process. In recent years, with the rapid development of economy, the fields of communication, internet and the like have also undergone high-speed development, and optical fibers play a crucial role in this process by virtue of their excellent performance. Compared with the traditional copper cable material, the optical fiber not only can obviously improve the transmission quality of signals, but also greatly improves the transmission distance.
However, in the process of shipping and using the optical fiber, there is usually a quality problem, which results in poor transmitted signals, so that the optical fiber needs to be tested, and the optical fiber test crimping connection device is produced. In the field of optical fiber communication, when an optical cable fails, the optical fiber needs to be measured in the whole process and the operation condition of the optical fiber needs to be detected, and an OTDR instrument (optical time domain reflectometer) is mainly used for positioning and testing the optical fiber at present to obtain parameters such as the length, a fault point, transmission attenuation, joint attenuation and the like of the optical fiber. In the actual measurement process of the OTDR instrument, a test blind area (the distance is generally between 30 meters and 80 meters) exists, that is, the OTDR instrument is directly connected with the optical fiber to be tested, if the test starting point and the actual fault point are within 80 meters, it is displayed that the state of the optical fiber to be tested presents a waveform and falls in the front end blind area of the OTDR curve, and the curve at the distance of 80 meters cannot accurately reflect the actual optical fiber state, which may have a great influence on the optical fiber test effect, thereby delaying the positioning and timely repairing of the optical fiber fault point.
In order to solve the problem of the front-end blind area, a preset tail fiber needs to be connected to the OTDR instrument, and then the preset tail fiber and the tested fiber are connected in a fiber cold-splicing or fusion mode to perform fiber fault detection. However, the method of optical fiber fusion splicing has great limitations in the use process, and mainly has the following points: 1. the cost is high and the carrying is difficult because a cold-connection terminal or a welding machine is matched; 2. when the two ends of the optical fiber are in cold connection or fusion connection, the construction process requirement is fine, and the detection construction difficulty is high; 3. the connection efficiency is low, the optical fiber cold joint or fusion time is long, and the efficiency of the whole-process measurement of the optical fiber and the detection of the running condition of the optical fiber is reduced.
