Consideration Of Ferrule Design Of Optical Fiber Connector

The connector is a complete component connected to the optical cable, which is usually in the male configuration. The female component is required to allow the connection of two connectors. The connector can be called a plug. The adapter is the mother assembly used to connect two connectors. The adapter is responsible for providing the alignment of the connector and the optical fiber in it.

Most fiber optic connectors are responsible for controlling the fiber alignment ferrule and connecting the connector to the rear body of the cable, but the structure of the rear can be complex and have an additional impact on the connection of the connector to the adapter.

The mechanical structure of ferrule and rear body varies from connector to connector and will be considered for each type of optical fiber connector. Due to its hardness and thermal stability, ferrule is usually made of ceramic material. The tube polymer ferrule is also widely used. This special ceramic is called zirconia. The hardness and coefficient of thermal expansion of this material are very similar to that of glass, and it is also well polished.

Conclusion: the ferrule design of optical fiber connector must consider the design of its material and structure to ensure that it meets the requirements of application specifications.
