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. While the small size of fibre optic connectors does not mean they play a minor role, the type of connector you use affects the overall efficiency of light transmission across the fibre network. It is a precise coupling device that joins fiber optic cables quickly, enabling faster connection and disconnection than splicing. 5mm OD precision ceramic pins, the end face processing using PC or APC.
