The technology in the network communication industry is constantly developing, and with the implementation of urban optical networks, in recent years, technologies such as fiber optic connectors, optical cables, and optoelectronic equipment have also seen better development and wider applications.
As the core component of interconnect products, fiber optic connectors have naturally attracted people's attention. In fiber optic communication systems, the use of fiber optic connectors is also very large. It is an important connector electronic component used to connect and disconnect fiber optic signals.

Below are some common fiber optic connectors:
FC (F01) type fiber optic connector
The FC type connector mainly adopts a metal threaded connection structure, and its pin body uses precision ceramic pins with an outer diameter of 2.5mm. According to the different shapes of its pin end faces, it can be roughly divided into two structures: FC/PC with spherical contact and FC/APC with oblique spherical contact. CJT connector technicians tell you that the FC type connector is currently the most widely used variety in the world and is also the main variety used in China.
Two SC (F04) type fiber optic connector
This is a molded plug-in coupled single-mode fiber optic connector, which has the same structural dimensions as the FC type, and the pin body is also a precision ceramic pin with an outer diameter of 2.5mm. In addition, its end face treatment adopts PC or APC grinding method; The fastening method is plug-in bolt type. This type of connector is inexpensive, easy to plug and unplug, with minimal fluctuations in connection losses, high compressive strength, and high installation density.
Three ST type fiber optic connector
The connector here adopts a key type bayonet locking structure (similar to BNC connection structure), and the pin body is a precision ceramic pin with an outer diameter of 2.5mm. In addition, the end face shape of the pin is usually PC surface.
