What are the advantages of using fiber optic connectors

With the continuous development of optical fiber communication technology, especially the development of high-speed local area network and optical access network, the application of fiber optic connectors in optical fiber systems will be more extensive. At the same time, it also puts forward more and higher requirements for optical fiber connectors. Its main development direction is: miniaturization of appearance and low cost, but the requirements for performance are getting higher and higher. In the coming period of time, various newly developed optical fiber connectors will provide useful assistance to the communication reconnaissance industry together with traditional FC, SC and other connectors.

The performance of fiber optic connectors, first of all, the optical performance, in addition to the interchangeability, repeatability, tensile strength, temperature and times of insertion and removal of fiber optic connectors.

1. Optical performance, the requirements for optical performance of optical fiber connectors are mainly the two most basic parameters of insertion loss and return loss.
Insertion loss, or connection loss, refers to the loss of effective optical power of the link caused by the lead of the connector. The smaller the insertion loss, the better, and the general requirement should be no more than 0.5dB.
Return loss refers to the ability of the connector to suppress the reflection of the optical power of the link, and its typical value should not be less than 25dB. In the practical application of the connector, the surface of the pin has been specially polished, which can make the return loss larger, generally not lower than 45dB.

2. Interchangeability and repeatability, fiber optic connectors are general passive devices. For the same type of fiber optic connectors, they can generally be used in any combination and can be used repeatedly. The additional loss introduced by this is generally All are within the range of less than 0.2dB.

3. Tensile strength, for a good optical fiber connector, the tensile strength is generally required to be no less than 90N.

4. Temperature, general requirements, fiber optic connectors must be able to work normally under the temperature of -40oC~+70oC.
