The performance of fiber optic connectors is first of all the optical performance, in addition to the interchangeability, repeatability, tensile strength, temperature and number of plugging and unplugging of fiber optic connectors.
(1) Optical performance: The requirements for optical performance of fiber optic connectors are mainly the two most basic parameters of insertion loss and return loss.
Insertion loss (InsertionLoss), that is, connection loss, 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 not be greater than 0.5dB.
Return Loss (ReturnLoss, ReflectionLoss) refers to the ability of the connector to suppress the reflection of link optical power, and its typical value should not be less than 25dB. In the actual application of the connector, the surface of the pin has been specially polished, which can make the return loss greater, generally not less than 45dB.
(2) Interchangeability and repeatability
Optical fiber connectors are general-purpose passive components. 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 optical fiber connector, it is generally required that its tensile strength should not be lower than 90N.
(4) temperature
As a general requirement, fiber optic connectors must be able to work normally at a temperature of -40oC~+70oC.
(5) Insertion times
The fiber optic connectors used can basically be plugged and unplugged more than 1000 times.
