Introduction and working principle of the DVP fiber fusion splicer

The DVP fiber optic fusion splicer is mainly used in major telecommunications operators, engineering companies, and private networks of enterprises and institutions. It is also used for fiber optic fusion in the production of passive and active components and modules.

Fusion splicing is an important process with the largest engineering quantity and the most complex technical requirements in optical fiber transmission systems, and its quality directly affects the transmission quality and reliability of optical fiber lines. Effective methods and correct fusion steps are extremely important.

There are generally three methods of welding: welding, movable connection, and mechanical connection. In practical engineering, fusion welding is generally used because it has low node loss, high reflection loss, and high reliability.

The basic working principle of the welding machine is as follows:

1. Alignment: Currently, fusion splicers align the fiber cores of two optical fibers, and locate the fiber cores through the CCD lens

2. Discharge: Two electrode rods release an instantaneous high voltage (several thousand volts, but it is a very short moment) to achieve the effect of breaking through the air. After breaking through the air, an instantaneous arc will be generated, which will generate high temperature and melt the front ends of the two aligned optical fibers. Due to the fact that the optical fibers are made of silicon dioxide material, commonly known as glass (of course, the purity of the optical fibers is much higher), it is easy to reach a molten state, Then the two optical fibers move forward slightly, and the two fibers stick together
