Optical fiber connector overview

Optical fiber connector is a device used to connect optical fibers. It plays a role in connecting, fixing and protecting optical fibers in optical fiber communications. The following is a review of fiber optic connector basics:


  1. Functions and basic principles:


    The main function of the optical fiber connector is to provide a reliable physical connection so that optical signals can be transmitted from one optical fiber to another optical fiber to realize the sending and receiving of data. Connectors usually consist of two parts: ferrule and socket. The ferrule is the end of the connector that contains the end of the optical fiber and connects to another connector by plugging into the socket. The socket is the other end of the connector that accepts the ferrule and ensures good alignment and connection.



  2. Importance:


    Fiber optic connectors play a vital role in fiber optic communications. They not only provide optical signal transmission channels, but also ensure the reliability and stability of the connection. A good connector can ensure the minimum loss of optical signals and the highest transmission efficiency, while also providing good mechanical strength and resistance to environmental interference. Therefore, it is very important to choose appropriate fiber optic connectors in network and communication systems.



  3. Different types of fiber optic connectors:


    There are many types of fiber optic connectors, each with its own specific design and application. Some common fiber optic connector types include:


  4. SC (Subscription Channel) connector: It is a common fiber optic connector that uses circular ferrules and sockets and is suitable for single-mode and multi-mode optical fibers.
  5. LC (Lucent Connector) connector: It is a small connector suitable for high-density fiber optic connections and is commonly used in data centers and local area networks.
  6. ST (Straight Tip) connector: It is an older connector type commonly used in multimode fiber optics, with a round ferrule and threaded connection mechanism.

The above are some common types of optical fiber connectors. The MTRJ connector is a special multi-mode optical fiber connector. Next, the characteristics and applications of the MTRJ connector will be highlighted.
