Performance of optical fiber fast connector

The performance of optical fiber connectors, first of all, is the optical performance. In addition, the interchangeability, repeatability, tensile strength, temperature, and number of plugging and unplugging of the optical fiber connector must also be considered.
1. Optical performance: The optical performance requirements of optical fiber connectors are mainly the two most basic parameters of insertion loss and return loss.
Insertion loss is connection loss, which refers to the loss of effective optical power of the link caused by the introduction 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 connector's ability to suppress link optical power reflection, and its typical value should be no less than 25dB. In practical connectors, the pin surface has been specially polished, which can make the return loss greater, generally not less than 45dB.
2. Interchangeability and repeatability
Optical fiber connectors are universal passive components. The same type of fiber optic connectors can generally be used in any combination and can be used repeatedly. The additional loss introduced thereby is generally less than 0.2dB.
3. Tensile strength
For finished optical fiber connectors, it is generally required that the tensile strength should not be less than 40N.
4. Temperature
Generally, fiber optic connectors must be able to be used normally at temperatures of -40°C ~ +70°C.
5. Number of plugging and unplugging
The fiber optic connectors currently used can generally be plugged and unplugged more than 1,000 times.
