The function of the fiber optical splicer is to maintain the fiber optical, and the fusion modes include the cold splicing and the hot melting. Therefore, in order to distinguish the two fusion modes of the fiber optical, we will tell the difference between them in the following.


1. Brief Introduction of Cold Splicing

Cold splicing is mainly used for the fusion between optical cables or between the fiber optical and the caudal fiber. What is used for this kind of cold connection is called the fiber optical cold connector. Fiber optical cold connector is used when two caudal fibers are connected. The main part in the connector is a precise V-groove. After the two caudal fibers are removed, the fiber optical cold splicer is used to achieve the docking of the two caudal fibers.


With the rapid development of FTTH fiber optical entering the home, the demand for the fiber optical cold splicer also greatly increases. The fiber optical quick connector and fiber optical cold splicer will play an irreplaceable role in the future development of FTTH. The operation of the fiber optical quick connector does not need the fusion machine, which has the characteristics of convenience, low cost and no site limitation.



2. Brief Introduction of Hot Melting

The fiber optical hot melting is a detailed work, especially in the port preparation, hot fusion, fiber coiling and other links. This requires careful observation, thoughtful consideration and standard operation. When the light is transmitted by the fiber optical, it will produce loss, which is mainly composed of the transmission loss of the fiber optical and the fusion loss of the fiber optical joint. Once the optical cable is purchased, its transmission loss is basically determined, and the fusion loss at the fiber optical joint is related to the site construction. Therefore, we should try our best to reduce the fusion loss at the fiber optical joint, so as to increase the transmission distance and reduce the transmission loss.



3. Difference of Two Fusion Modes of Fiber Optical

The fiber optical splicer and fiber optical cutter are used in the hot melting to connect the two fibers without any other auxiliary materials. The advantages are stable quality and small connection loss. The disadvantages include the high cost of the equipment, the limited storage capacity and the limitation of field work.


The cold splicing does not need to use too much equipment, and the fiber optical cutter can meet the requirements. However, each contact requires a quick connector. The advantages are easy to operate and no limitation of field work. The disadvantage is that the loss is large, which is about 0.1~0.2dB at each connection point.



No matter what kind of fusion mode, there are their most applicable scenarios. In order to facilitate the maintenance of the fiber optical, we should prepare fiber optical tools, such as the fiber optical splicer and the fiber optical cutter and so on. Only by making good use of these machines can we solve the problems related to the fiber optical.
