The main methods include permanent connection, emergency connection, and active connection.

1. Permanent fiber optic connection (also known as thermal fusion)

This connection is achieved by melting and connecting the connection points of two optical fibers together through discharge. Generally used for long-distance connections, permanent or semi permanent fixed connections. Its main feature is that the connection attenuation is relatively low among all connection methods, with a typical value of 0.01~0.03dB/point. But when connecting, specialized equipment (fusion splicer) and professional personnel are required for operation, and the connection point also needs to be protected by a dedicated container.

2. Emergency connection (also known as cold fusion)

The emergency connection mainly uses mechanical and chemical methods to fix and bond two optical fibers together. The main feature of this method is that the connection is fast and reliable, with a typical attenuation of 0.1~0.3dB/point. But long-term use of the connection point will be unstable and the attenuation will increase significantly, so it can only be urgently needed in a short period of time.

3. Activity Connection

Activity connection is a method of connecting sites to each other or sites to optical cables using various fiber optic connection devices (plugs and sockets). This method is flexible, simple, convenient, and reliable, and is commonly used in computer network cabling within buildings. Its typical attenuation is 1dB/joint.
