Some optical fiber connector types are as follows: Some optical fiber connector types are as follows:
LC: square optical fiber connector of the push LC: square optical fiber connector of the push-pull snap-in type

SC: standard optical fiber conn SC: standard optical fiber connector

FC: round optical fiber connector with screw thread FC: round optical fiber connector with screw thread

ST: round plug-in optical fiber connector in optical fiber connector

MT-RJ: square transceiver optical fiber connector RJ: square transceiver optical fiber connector
