Due to the development of the communication industry, the frequency of use of fiber optic connectors has been greatly enhanced. There are many types of fiber optic connectors, but the performance of all fiber optic connectors includes optical compatibility, repeatability, tensile strength, temperature and Number of plugs and so on. Below is a brief analysis of the performance of our major fiber optic connectors. Due to the development of the communication industry, the frequency of use of fiber optic connectors has been greatly enhanced. There are many types of fiber optic connectors, but the performance of all fiber optic connectors includes optical compatibility, repeatability, tensile strength, temperature and Number of plugs and so on. Below is a brief analysis of the performance of our major fiber optic connectors. (1) Optical performance: For the optical performance requirements of optical fiber connectors, the two most basic parameters of insertion loss and return loss are mainly used. Insertion loss (InsertionLoss) is the loss of the effective optical power of the link caused by the introduction of the connector. The smaller the insertion loss, the better. Generally, the requirement should be no more than 0.5dB. Return Loss (ReflectionLoss) refers to the ability of the connector to suppress the reflection of the link optical power, and its typical value should be no less than 25dB. In the actual application of the connector, the surface of the pin has been specially polished to make the return loss larger, generally not less than 45dB. (2) Interchangeable and repetitive optical fiber connectors are general-purpose passive devices. For the same type of optical fiber connectors, they can be used in any combination and can be used repeatedly. Therefore, the additional losses introduced are generally In the range of less than 0.2dB. (3) Tensile strength For a good fiber optic connector, the tensile strength is generally required to be no less than 90N. (4) Temperature Generally, the fiber optic connector must be able to operate normally at temperatures between -40oC and +70oC. (5) Number of insertions and removals The fiber connectors currently used can be plugged and unplugged more than l000 times.
