There are many types and types of fiber optic active connectors, and the most commonly used active connector in China is the FC series connector. It is the primary type selected in the trunk system and will remain the primary type for a long period of time in the future; SC type connectors are the primary type of fiber optic LAN, CATV, and user network. In addition, ST type connectors are also used in a certain amount.
The FC series connector is a type of connector made of metal materials with spiral connections and external components. It is the main type of connector used in China's telecommunications network, and China has formulated national standards for FC type connectors.
Currently, the pins and sleeves of optical fiber active connectors are made of oxidized ceramic materials near the expansion coefficient of quartz optical fibers, which have great wear resistance and certain durability, as well as a stable size, to ensure that there is no wear, deformation, and accurate alignment when plugging and unplugging more than 1000 times.
FC type is a standardized type of single core fiber optic connector, with a plug connector plug structure.
The characteristic of FC/PC type fiber optic connectors is that they have a cylindrical centering sleeve with an outer diameter of 2.5 mm and an M8 threaded locking structure. The spherical end face of the FC/PC type fiber optic connector reduces sensitivity to dust and pollutants.
The SC type movable connector is limited by high-strength engineering plastic and has a rectangular plug-in connection structure. Its characteristics are simple technology, low production cost, simple plug-in operation, small space occupation, dense installation, and can be made into a multi-core connector. The defect is that it is prone to deformation and has poor connection reliability. It is usually used for non main optical line connections or optical path measurement connections.
