What are the indoor optical cable connections? Changzhou beam optical cable manufacturer to give you a brief introduction of permanent, emergency, and mobile convergence.

 

1. Permanent binding optical cable (also known as hot melt) :

 

This connection is made by melting and connecting the junction points of two optical cables by means of electric discharge. Usually used for long distance connection, permanent or semi-permanent fixed connection. Its main characteristic is that the cohesive attenuation is the lowest among all the cohesive devices, and the typical value is 0.01~0.03dB/ point. However, special equipment (welding machine) and professional staff are required to operate the joints, and special containers are required to maintain the joints.

 

2. Emergency connection (also known as cold fusion) :

 

Emergency connection is mainly by mechanical and chemical means, two optical fibers are fixed and bonded together. The main characteristic of this method is that the cohesion is fast and reliable, and the typical cohesion attenuation is 0.1db to 0.3db/point. However, the long-term use of the joints will be unstable and the attenuation will be greatly increased, so it should be used urgently only in a short time.

3. Event cohesion:

 

Active bridging is a way to connect a station to a station or station to a cable using a variety of beam and cable bridging devices (plugs and sockets). This method is sensitive, brief, convenient and reliable. Its typical attenuation is 1dB/ connector.
