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

(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 (InsertionLoss) is the connection loss, which refers to the loss of the 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 (ReturnLoss, ReflectionLoss) 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 less than 45dB.

(2) Interchangeability and repeatability

Optical fiber connectors are general passive devices. For the same type of optical fiber connectors, they can generally be used in any combination and can be used repeatedly. The additional loss introduced by this is generally within the range of less than 0.2dB. (3) Tensile strength

For a well-made fiber optic connector, it is generally required that its tensile strength should not be less than 90N.

(4) Temperature

As a general requirement, fiber optic connectors must be able to be used normally at a temperature of -40oC~+70oC.

(5) times of plugging and unplugging

The fiber optic connectors used can basically be plugged and unplugged more than 1000 times.
