Optical cable connection method
1. permanent optical fiber connection, also known as hot melting: the connection point of two optical fibers is connected by discharge melting. Generally used for long-distance connection, permanent or semi-permanent fixed connection. Its main feature is that the connection attenuation is the lowest among all connection modes, but the connection requires special equipment and professional operation, and the connection point also needs special container protection;

Second, emergency connection, also known as cold melting: mainly through mechanical and chemical methods, two optical fibers are fixed and bonded together. The main feature of this method is fast and reliable connection, but after long-term use, the connection point will be unstable and the attenuation will increase greatly, so it can only be used urgently in a short time;

3. Movable connection: Movable connection is a method of connecting stations or stations with optical cables by using various optical fiber connectors, plugs and sockets. This method is flexible, simple, convenient and reliable, and is often used for computer network wiring in buildings.
