The performance of the china optitap 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 optical performance requirements of china optitap connector are mainly the two most basic parameters of insertion loss and return loss.
Insertion loss is the connection loss, which refers to the loss of effective optical power of the link caused by the introduction of the china optitap connector. The smaller the insertion loss, the better, and the general requirement should be no more than 0.5dB.
Return loss refers to the ability of china optitap connector to suppress the reflection of optical power of the link, 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 larger. Generally not less than 45dB.
(2) Interchangeability and repeatability
china optitap connector is a general passive device. For the same type of optical fiber connector, it 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 good china optitap connector, it is generally required that its tensile strength should not be less than 90N.
Generally, the china optitap connector must be able to be used normally at the temperature of -40℃~+70℃.
(5) times of plugging and unplugging
The china optitap connector currently used can generally be plugged and unplugged more than 1000 times.
4. Some common fiber optic connectors
According to different classification methods, china optitap connectors can be divided into different types, which can be divided into single-mode optical fiber connectors and multi-mode optical fiber connectors according to different transmission media; FC, SC, ST, D4 according to different structures , DIN, Biconic, MU, LC, MT and other types; according to the pin end face of the connector, it can be divided into PC (UPC) and APC; according to the number of fiber cores, there are single-core and multi-core points.
