The methods mainly include permanent connection, emergency connection, and active connection.
1. Permanent fiber connection (also called hot melt):
This kind of connection melts and connects together the connection points of the two fibers by means of discharge. It is generally used for long-distance connection, permanent or semi-permanent connection. Its main feature is that the connection attenuation is the lowest among all connection methods, typically 0.01 to 0.03 dB/point. However, when connecting, special equipment (fusion machine) and professionals are required to operate, and the connection points need to be protected by special containers.
2. Emergency connection (also called cold melting):
Emergency connections are mainly mechanical and chemical methods that fix and bond the two fibers together. The main feature of this method is that the connection is fast and reliable, and the typical attenuation of the connection is 0.1~0.3 dB/point. However, long-term use of connection points will be unstable, and attenuation will increase significantly, so it can only be used in emergency for a short period of time.
3. Activity connection:
Active connection is a method of connecting a site and a site or site to an optical fiber cable using various optical fiber connection devices (plugs and sockets). This method is flexible, simple, convenient, and reliable, and is often used in computer network wiring in buildings. Its typical attenuation is 1dB/joint.
