How they differ

ST fiber connector Use equipment labels and an exterior manufacturer illustration. Do not inspect the end face with your eye or an ordinary magnifier.
SC fiber connector Use the manufacturer product reference to confirm the housing. The stylized side/front sketch is an identification aid pending specialist diagram review; color is not enough.
LC fiber connector Use the manufacturer product reference to confirm the housing. The stylized side/front sketch is an identification aid pending specialist diagram review; color is not enough.
