The Core Components of The Fiber Optic Connector: Ceramic Ferrule

What is ceramic ferrule? As the name suggests, the main material of the ceramic ferrule is ceramics, however, thia is not just ceramic so simple. Ceramic ferrules must be used in fiber optic communication, it is to ensure the communication quality is a very important role.

We all know that fiber connection technology is divided into two categories, one class is permanently connected, often called fixed joints dead joints; another class activities removable connection, often referred to as the union, need to use fiber optic connector. In the transmission network, a fiber optic 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 most important role of the ceramic ferrule fiber physical docking (also known as fiber cold splice), 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 ciruit in the plug and receptacle, the ferrule and sleeve are the key components of fiber optic connector. The diameter of only 0.125mm optical fiber must pass through the inner bore of the ceramic ferrule, and to maintain a linear transmissin 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 ferrule.

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.
