Methods are permanent connection, emergency connection, active connection.
1. Permanent fiber connection (also known as Hot Melt): This connection is a discharge method that fuses and connects the connecting points of two fibers. Generally used in long-distance connections, permanent or semi-permanent fixed connection. The main feature is that the connection attenuation is the lowest in all connection methods, the typical value is 0.01~0.03db/point.
When connecting, however, special equipment (welding machines) and professionals are required to operate, and connection points need to be protected by a dedicated container.
2. Emergency connection (also known as) cold melt: The emergency connection is primarily a mechanical and chemical method of fixing and bonding two fibers together. The main feature of this method is that the connection is fast and reliable, and the connection typical attenuation is 0.1~0.3db/point.
But the connection point long-term use will be unstable, attenuation will also increase significantly, so only a short period of time for emergency use.
3. Active Connection: An active connection is a method of connecting a site to a site or site to an optical cable using a variety of fiber optic connection devices (plugs and sockets). This method is flexible, simple, convenient and reliable, and is used in the wiring of the computer network in the building. The typical attenuation is the 1db/connector.
