The Performance Of The Fiber Connector

The performance of optical fiber connectors is first of all optical properties. In addition, the interchangeability, repetitiveness, tensile strength, temperature and plugging times of optical fiber connectors must be considered.

(1) Optical performance: The requirements for the optical performance of optical fiber connectors are mainly the two most basic parameters of the two most basic parameters.
InsertionLoss is the connection loss, which refers to the loss of the link effective light power caused by the introduction of the connector. The smaller the insertion loss, the better, the general requirements should not be greater than 0.5dB.
ReturnLoss (ReflectionLoss) refers to the inhibitory ability of the connector to reflect the linked light power reflection, and its typical value should not be less than 25DB. The actual application connector, the surface of the pins is specially polished, can make the back loss losses greater, generally not less than 45DB.

(2) Interchangeability, repetitiveness
The optical fiber connector is a general passive device. For the same type of optical fiber connector, it can generally be used arbitrarily and can be repeatedly used again. The additional loss introduced from this is generally less than 0.2DB.

(3) Tensile strength
For the good optical fiber connectors, it is generally required that its tensile strength should not be less than 90N.

(4) Temperature
Generally, optical fiber connectors must be used normally at the temperature of -40OC ~+70OC.

(5) Insert number
The optical fiber connector used can basically be plugged in more than 1 000.
