An optical fiber connector is a device that connects an optical fiber to another optical fiber. It is a connecting device that can be repeatedly plugged and pulled out between an optical fiber and another optical fiber, so it is also widely called an optical fiber jack pulg.
The optical fiber connector realizes the low-loss connection between the optical fiber and the optical fiber or the optical fiber and the cable, overcomes the influence of the optical fiber connection on the signal, and enables our communication transmission to be effectively transmitted in different environments. And the different models of optical fiber connectors meet our needs in different optical fiber connection situations.
The optical fiber connector has excellent performance and outstanding function, and its application scope will not only realize the connection of optical fiber, but also the optical fiber connector has been widely used in optical fiber transmission lines, optical fiber distribution frames, optical fiber testing instruments and meters.
In order to adapt to various environments, the performance characteristics of optical fiber connectors have become very important. For example, the optical performance, interchangeability, repeatability, tensile strength and temperature adaptability of optical fiber connectors have specific requirements.
The first is the optical performance. In addition, the interchangeability, repeatability, tensile strength, temperature and plugging times of the optical fiber connector must also be considered.
1. Optical performance of optical fiber connector
The requirements for the optical performance of optical fiber connectors are mainly the two most basic parameters of insertion loss return loss.
Insertion loss is connection loss, refers to the loss of effective optical power of the link caused by the introduction of optical fiber connectors. The smaller the insertion loss, the better, and the general requirement should be no more than 0.5dB.
2. Interchangeability and repeatability of optical fiber connectors
Optical fiber connectors are universal passive devices. Generally, the same type of optical fiber connectors can be used in any combination and can be used repeatedly. The additional loss introduced thereby is generally within the range of less than 0.2dB.
3. Tensile strength of optical fiber connector
For a finished fiber optic connector, it is generally required that its tensile strength should not be less than 90N.
4. The temperature of the optical fiber connector
Generally, the optical fiber connector must be able to be used normally at a temperature of -40°C to +70°C.
5. The plugging times of the optical fiber connector
Basically, the optical fiber connectors used can be plugged and pulled out more than 1000 times.
