Connection method of optical cable

Release Time：

2024-04-03

This connection is achieved by melting and connecting the connection points of two optical fibers together using a discharge method. Generally used for long-distance connections, permanent or semi permanent fixed connections. Its main characteristic 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 melt)

The main methods include permanent connections, emergency connections, and active connections.
1. Permanent fiber optic connection (also known as hot melt)
This connection is achieved by melting and connecting the connection points of two optical fibers together using a discharge method. Generally used for long-distance connections, permanent or semi permanent fixed connections. Its main characteristic 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 melt)
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. However, long-term use of the connection point can lead to instability and a significant increase in attenuation, so it can only be urgently needed in a short period of time.
3. Activity Connection
Active connection is a method of connecting stations to stations or stations to optical cables using various fiber optic connecting devices (plugs and sockets). This method is flexible, simple, convenient, and reliable, and is commonly used in computer network wiring inside buildings. Its typical attenuation is 1dB/joint.
