What are the advantages of fiber optic connectors?

With the continuous development of fiber optic communication technology, especially the development of high-speed LANs and optical access networks, fiber optic connectors in the fiber optic system will be more widely used, at the same time, also put forward more fiber optic connectors, higher requirements, the main direction of its development is: miniaturization of the appearance of the cost of low cost, while the performance requirements are increasingly high.

-I. What are the advantages of fiber optic connectors? Fiber optic connector performance, first of all, optical performance, in addition to consider the interchangeability of fiber optic connectors, repeatability, tensile strength, temperature and the number of times of insertion and removal, etc. 1, optical performance. For the optical performance of fiber optic connectors requirements, mainly insertion loss component consumption and return loss of the two most basic parameters. Insertion loss (InsertionLoss) that is, connection loss, refers to the connector's lead into the link caused by the loss of effective optical power, insertion loss the smaller the better, the general requirements should not be greater than 0.5dB. Return loss (ReturnLoss, ReflectionLoss) refers to the connector on the link optical power reflection of the connector's ability to inhibit the typical value should not be less than 25dB. Not less than 25dB, the actual application of the connector, the pin surface has been specially polished, can make the return loss is greater, generally not less than 45dB. 2, interchangeability, repeatability. Fiber optic connector is a universal passive device, for the same type of fiber optic connector, generally can be used in any combination, and can be repeated many times, which leads to additional loss of an electronic connector are generally in the range of less than 0.2dB. 3, tensile strength. For good fiber optic connectors, the general requirements of its tensile strength should not be less than 90N. 4, temperature. General requirements, fiber optic connectors must be -40oC ~ +70oC temperature can be used normally.
