Performance Of Fiber Optic Connector

The performance of optical fiber connector is optical performance first. In addition, the interchangeability, repeatability, tensile strength, temperature and insertion frequency of optical fiber connector are also considered.

(1) optical properties: the requirements for optical properties of fiber optic connectors are mainly the two basic parameters of insertion loss and echo loss.

The insertion loss (InsertionLoss), the connection loss, refers to the loss of the effective optical power of the link caused by the import of the connector. The smaller the insertion loss the better, the general requirement should not be greater than 0.5dB.

ReturnLoss (ReflectionLoss) refers to the ability of the connector to suppress the light power reflection of the link, and its typical value should not be less than 25dB. The actual application of the connector, the needle surface after a special polishing treatment, can make the echo loss greater, generally not less than 45dB.

(2) interchangeability and repeatability

Optical fiber connector is a universal passive device. For the same type of optical fiber connector, it can be used at any time and can be used repeatedly, and the additional loss from it is generally less than 0.2dB.

(3) tensile strength

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

(4) temperature

Generally, the fiber optic connector must be used normally at the temperature of -40oC~+70oC.

(5) the number of inserting times

The fiber connector that is used now can be basically plugged in more than l000 times.
