What are the link modes of fiber optic cables?

2021-10-23

An optical fiber cable is a communication line in which a certain number of optical fibers compose a cable core in a certain manner, and are covered with a sheath, and some are also covered with an outer sheath to realize the transmission of optical signals. Today, Fiber Hope mainly introduces the link method of optical fiber and cable to you.

The connection methods of fiber optic cables mainly include permanent connection, emergency connection, and active connection.

1. Permanent connection

Permanent optical fiber connection (also called hot fusion) This kind of connection is the use of electric discharge to melt the connection point of two optical fibers and connect them together. Generally used in long-distance connection, permanent or semi-permanent fixed connection. Its main feature is that the connection attenuation is the lowest among all connection methods, with a typical value of 0.01~0.03dB/point. However, when connecting, special equipment (fusion splicer) and professionals are required to operate, and the connection point also needs to be protected by a special container.

2. Emergency connection

Emergency connection (also called) 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, and the typical attenuation of the connection is 0.1~0.3dB/point. However, the connection point will be unstable for long-term use, and the attenuation will increase greatly, so it can only be used for emergency in a short time.

3. Active connection

Active connection Active connection is a method that uses various optical fiber connection devices (plugs and sockets) to connect the site to the site or the site to the optical cable. This method is flexible, simple, convenient, and reliable, and is mostly used in computer network wiring in buildings. Its typical attenuation is 1dB/connector.
