Of the more than a dozen types of fibre-optic connectors available, the four most commonly used today are LC, SC, FC, and ST. An optical fiber connector is a device used to link optical fibers, facilitating the efficient transmission of light signals. Unlike fiber splicing, which is permanent, connectors allow for easy connection and disconnection of cables, making them ideal for maintenance and flexibility in. The optical fiber connector is a kind of detachable passive optical component used in the connection between fiber to fiber, the light source to the fiber, and fiber to the detector to achieve the light maximize coupling to the receiving fiber. It is a precise coupling device that joins fiber optic cables quickly, enabling faster connection and disconnection than splicing.
