Fixed connection is a permanent connection

Fixed connections for cable lines, fiber-optic cables to connect the fixed amount of work is great, therefore, has a fixed connection on the line quality is very important. Fiber optic connection into the fixed welding and mechanical connection method, the fixed optical fiber connector loss, due to be connected by the fiber itself and the external process parameters and other factors, so the consistency of fiber connection loss subject to certain restrictions. Project to measure the average connection loss, from the practical point of view, 0.5dB connection loss has to meet the basic requirements, but the connection with optical fiber production process and technology continues to mature, fiber connection loss has been greatly reduced. In fiber-optic connection technology is widely used welding method, this method can be done to connect the average loss is less than 0.1dB, the method is the use of fiber-optic point discharge electrode welding machine, arc generated heat to melt into one optical fiber is connected .
