Different applications of fixed and movable connections in the connection of optical fibers

The active connection of optical fibers is achieved by means of fiber optic connectors. An active connection point in an optical link is a clear split interface. In the choice between movable and fixed connections, the advantages of fixed connections are reflected in lower cost and lower optical loss, but less flexibility, while the opposite is true for movable connections. Network design needs to be based on the entire link situation, flexible choice of active and fixed connections to ensure both flexibility and stability, so as to give full play to their respective advantages. The active connection interface is an important interface for testing, maintenance, and change. It is relatively easier to find the point of failure in the link than a fixed connection, adding convenience to the replacement of faulty devices, thus improving system maintainability and reducing maintenance costs.
