Which option is not used as an optical fiber connector?

The ability to tell fiber connectors apart from copper cabling terms is what’s being tested. SC, LC, and ST are all standard styles used to terminate and connect optical fiber strands, each with its own physical design (SC is a push-pull square style, LC is a small form-factor with a 1.25 mm ferrule, ST uses a bayonet-style coupling). S/FTP, on the other hand, describes Shielded Foiled Twisted Pair—an insulation/shielding scheme for copper Ethernet cables, not a fiber connector. There isn’t a fiber termination called S/FTP, so it isn’t used for optical fiber connections.
