The core components of the fiber connector: ceramic ferrule

What is ceramic Chaxin? Ceramic ferrule’s main material ceramic. Ceramic ferrules must be used in optical fiber communication, it is a very important role to ensure the communication quality.     Fiber connection technology is divided into two categories, one is permanently connected, often called fixed joints dead joints; other is a removable activities connect, often referred to as the union, need to use the fiber optic connector. In the transmission network, a cable connection between the permanent connection, the optical fiber connector is mainly used to implement the system between devices, between the equipment and instruments, equipment and between the optical fibers and the optical fibers and optical fiber between nonpermanent the fixed connection, it is the optical communication system of the most widespread and the largest use of basic passive devices. Matching ceramic material with quartz fiber thermal, physical and chemical properties and stability, as the core device with ceramic ferrule fiber optic connectors has been developed rapidly.               The ceramic ferrule most important role is to achieve the physical docking of the optical fiber (also known as fiber cold continuation), often used in conjunction with ceramic sleeve. Ceramic cylindrical tube fired zirconia ceramic ferrule, hard texture, delicate white color accuracy of the finished sub-micron level, is the most commonly used in optical fiber communication network, the largest number of precision positioning pieces, often used for the manufacture of the optical connector, the optical coupling of the devices, and the like. Like the circuit in the plug and receptacle, the ferrule and the sleeve are the key components of optical fiber connector. The diameter of only 0.125 mm optical fiber must pass through the inner bore of the ceramic ferrule, and to maintain a linear transmission of the state; connected to the outgoing optical fiber in the other end of the ceramic ferrule. Straight and precise connection directly affect the transmission efficiency of the optical fiber. Ceramic ferrule is not only highly internal hole diameter, while the outer diameter and concentricity requirements higher. And the optical connector because of the need for multiple plug, after repeated use must maintain the same accuracy of the same, very high demands on the material density. The ceramic ferrule classification and features Ceramic ferrule in accordance Dimensions is divided into three categories of SC, LC, and non-standard, in accordance with its precision, can be divided into two kinds of single-mode and multimode. The industry is often referred to as SC singlemode ferrule, SC multimode ferrule, LC singlemode ferrule, LC multimode ferrule, non-standard mortise. The ceramic ferrule characteristics depend on the characteristics of the material zirconia, mainly reflected in the good thermal stability, high hardness, high melting point, and wear-resistant, high machining accuracy.
