The SC connector is a snap-in connector widely used in single mode

The ST connector (registered trademark of AT&T) was one of the first connectors that used ceramic splints and still one of the most popular connectors for multimode networks, mostly for buildings and campuses. It has a bayonet mount and a long, cylindrical splint to support the fiber. Most splints are ceramic, but there are some metal or plastic. Since they have a spring, you must ensure that they are inserted correctly. If you have high losses, reconnect them to see if there is any difference.     

The SC connector is a snap-in connector widely used in single-mode systems for its excellent
performance and in multimode systems because it was the first connector chosen as standard by the
TIA-568 standard (any connector approved by FOCIS standards is now accepted). It is a snap-in
the connector that fits with a simple push-pull mechanism (which prevents accidental disconnection). It is also available in a duplex configuration.

The LC is a relatively new connector that uses a 1.25 mm splint, half the size of the ST. It is generally used in duplex format.   It is a standard ceramic splint connector, which can be placed with any adhesive. Since it has a good performance, it is the most preferred single-mode connector and is the one is chosen for multimode transceivers for gigabit or higher speeds, even for multimode Ethernet and fiber channels.
