The carrier-grade optical fiber quick connector is a detachable device used for connection between optical fibers and optical fibers. The main purpose of fiber optic connectors is to connect optical fibers. Optical fiber connectors have been widely used in optical fiber communication systems.
Carrier grade fiber optic quick connector
There are many types of it, but the basic structure of various types of fiber optic connectors is the same, that is, it consists of three parts, two pins and a coupling tube. The use method of the optical fiber connector is to insert and fix the optical fiber in the ferrule, and after polishing the surface of the ferrule, the alignment is realized in the coupling tube.
What are the main aspects of the selection of carrier-grade fiber optic quick connectors?
1. Durability
This is an indicator that a fiber optic connector can withstand regular use. Durability is a function of mechanical structure and materials, and connector durability is generally measured by vibration, drop, crush, and bend tests.
2. Loss
For a complete connector, the loss of a fiber optic cable connector is usually expressed as the average loss and the standard error of the loss. The smaller the insertion loss, the better, and the general requirement should be no more than 0.5dB.
3. Repeatability
Repeatability is primarily limited by the cleanliness of mechanical design structures, materials, and connections. A poor connector can exacerbate losses to the point of system failure if the connector cannot withstand reverse mating. In general, for 1000 repeated connections, seek connectors with repeatable characteristics that do not vary by more than 0.2dB.
4. Temperature stability
The average loss of fiber optic cable connectors due to temperature changes is caused by thermal expansion and contraction of connector components. This temperature-induced change in losses can cause temporary system interruptions. In severe cases, the plugs of the connector will be separated from each other, which is the so-called "jacking" phenomenon. Therefore, the selection of optical fiber connectors generally requires the normal operating temperature to be between -40°C and 70°C.
5. Tensile strength
Tensile strength is an indicator of how much tensile force the fiber, cable, or connector can withstand before damage occurs on the cable that has been terminated to the connector. It is generally required that the tensile strength of optical fiber connectors should not be less than 90N.
