What is fiber optic connector? What are the domestic and international manufacturers of fiber optic connectors?

First, what is a fiber optic connector? Fiber optic connector is a device used to connect optical fibers, which usually consists of a ferrule, socket, fuse, shell, etc. Its role is to make the two optical fibers in the connection of the position of precise alignment, the formation of low-loss, low-reflective optical signal transmission channel, so as to ensure the stability and reliability of optical signal transmission. The main role of the fiber optic connector is to realize the connection and decoupling between optical fibers. In practice, fiber optic connectors are usually widely used in fiber optic communications, fiber optic sensing and other fields, such as fiber-to-the-home (FTTH) network, fiber optic local terminal (OLT) and optical terminal equipment (ONT) connection, fiber optic connection in the server room. From the point of view of connection mode, fiber optic connector has two main connection modes: FC connection and SC connection, FC connection refers to the installation of FC connector on one side of the fiber optic connector, and the installation of matching FC socket on the other side, which is suitable for high-speed, high-density transmission; SC connection refers to the installation of SC connector on one side of the fiber optic connector, and the installation of matching SC socket on the other side, which is suitable for low-speed, low-density transmission; the connection method is suitable for low-speed, low-density transmission. This connection is suitable for low-speed, low-density transmission. In addition to FC and SC connections, there are also different connections such as ST, LC and MU. These different connection methods are usually realized by different connectors and sockets with different scope of application and characteristics. The main features of fiber optic connectors include low loss, low reflection, high precision and so on. In optical signal transmission, loss is a very critical index, which directly affects the performance and reliability of fiber optic connectors. In order to ensure low-loss transmission, fiber optic connectors usually use high-quality materials and manufacturing processes, such as the use of ceramic ferrule, metal shell, etc., to ensure the stability and reliability of optical signal transmission. In addition, fiber optic connectors are characterized by high precision. In optical signal transmission, precision is very important because any small deviation may lead to signal loss and distortion. Therefore, fiber optic connectors usually adopt precise manufacturing processes and equipment to ensure accurate alignment between the ferrule and socket, thus achieving high precision signal transmission. Types of fiber optic connectorsFiber optic connectors can be divided into a variety of types according to their different structures and uses, the following is a brief introduction to some of the common types.SC-type connectorsSC-type connectors are cylindrical connectors, which have a relatively small size and are very suitable for high-density fiber optic connections.SC-type connectors have a fixed spring on the plug, which ensures a stable connection between the plug and receptacle.LC-type connectorsLC-type connectorsLC-type connectors have a fixed spring on the plug to ensure a stable connection between the plug and receptacle. LC type connector LC type connector is a very common type of connector, it is relatively small, very suitable for high density fiber optic connection, LC type connector plug is relatively slender, its size is similar to the RJ45 network connector. st type connector ST type connector ST type connector is a kind of cylindrical connector, its size is larger, suitable for medium density fiber optic connection. st type connector is usually used for multi-mode fiber connection, ST type connector is usually used for multi-mode fiber connection. Usually used for multi-mode fiber connection, there is a thread lock on its plug, which can ensure a firm and stable connection. Fiber optic connector is an indispensable and important part of optical communication system, which can ensure the strength, quality and stability of the signal and directly affect the performance, reliability and stability of the network. When selecting and using fiber optic connectors, you need to select according to the specific application needs and system requirements, and pay attention to the number of times the connector is plugged and unplugged, cleaning and maintenance issues to ensure that the connector's performance and reliable!
