(Optical fiber fusion splicing is to use a fully automatic special equipment - a fusion splitter (FusionSplitter) to connect the optical fibers to be connected in the two sections of optical cable respectively. Connection method The connector is small in size, high in mechanical strength, and stable in performance after optical fiber connection, so it is widely used. After the optical fiber is spliced, a certain amount of loss will be generated when the light transmits to the connector, which is called splice loss or splice loss. Since the quality of optical fiber connection affects parameters such as the limit of transmission loss of optical fiber line and the transmission distance of optical fiber line without repeater amplification, it is required that the melting loss at the optical fiber joint be as small as possible to ensure the transmission quality of optical fiber CATV signal.)
