Of the more than a dozen types of fibre-optic connectors available, the four most commonly used today are LC, SC, FC, and ST. Unlike fiber splicing, which is permanent, connectors allow for easy connection and disconnection of cables, making them ideal for maintenance and flexibility in. The fiber connector is called a fiber optic or optical fiber connector. The connector mechanically orients the fiber cores, allowing light to pass and travel through. This article explores the wide range of fiber optic connector types, from legacy SC and ST to modern MPO/MTP and VSFF designs. Good connectors use tiny ceramic ferrules to precisely center each fiber core.
