A fiber optic connector is a device that connects a fiber to another fiber, which is a connecting device that can be repeatedly unplugged between the fiber and the fiber, and is therefore widely known as a fiber-optic active joint.
Fiber optic connectors According to the structure of its connector head, fiber optic connectors are divided into many kinds, such as FC, SC, ST, LC and other models of connectors. But same, the core components of various types of fiber connectors are the same, using high-precision components, namely two pins and a coupling tube to achieve fiber alignment.
The presence of various types of fiber connectors solves the problem of optical fiber connectivity under different conditions. In order to adapt to various environments, the performance characteristics of fiber optic connectors become very important. For example, optical properties of optical fiber connectors, interchangeability, Fiber Optic Connector repeatability and its tensile strength and temperature adaptability are specific requirements. Among them, the optical performance is the most important, it determines the optical fiber transmission power size. Because the optical fiber connector is a passive device, belonging to a general-purpose device, which requires that the fiber connector must be able to use any combination, re-use, that is, Fiber Optic Connector fiber optic connectors, interchangeability and duplication of performance better. In addition, there are requirements in the industry: Fiber connector tensile strength must not be less than 90N, and the normal use of fiber optic connectors temperature range must be between 40 ℃ to 70 ℃.
Optical fiber-related product types are more, Fiber Optic Connector but also in constant update, where fiber connector is a very important product component, it improves the flexibility of network cabling.
The performance of optical fiber connectors, first of all optical performance, in addition to the optical fiber connector interchangeability, repeatability, tensile strength, temperature and the number of plug-and-pull.
1, optical properties: For optical fiber connectors, Fiber Optic Connector the optical performance requirements, mainly the insertion loss and return loss of the two basic parameters.
Insertion loss (Insertionloss) is the connection loss, which is 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 requirements should not be greater than 0.5dB.
The Echo loss (Returnloss, Reflectionloss) is the ability of the connector to reflect the link light power, and its typical value should not be less than 25dB. The actual application of the connector, Fiber Optic Connector the needle surface through a special polishing treatment, can make the return loss of greater, generally not less than 45dB.
Fiber optic connectors are common passive devices, for the same type of fiber optic connectors, can be used in any combination, and can be reused for many times, the additional loss of imports is generally less than 0.2dB.
3. Tensile strength
For a good optical fiber connector, the general requirements of its tensile strength should not be less than 90N.
General requirements, fiber optic connectors must be at the -40oc~+70oc temperature can be used normally.
5, the number of plug-and-pull
Currently used fiber connectors can generally be plugged l000 more than once.
After understanding the structure and main properties of the fiber connector, the effect of fiber optic connectors We are not difficult to think of: optical fiber connectors to achieve the optical fiber and the relationship or the low loss between fiber and cable connection, its customer service to the optical fiber connection to the signal effect, so that our communication transmission can be in different environments for effective transmission. and the different types of fiber connectors meet our needs in different optical fiber connections.
