The first widely used connector in the data world, at least in North America, was the ST, sometimes called Snap and Twist. This connector dealt successfully with many of the limitations of the SMA. Ceramic ferrules could be molded and machined with the submicron tolerances required for 9 micron core single mode fibers, field termination and polishing were a little easier, and the connector ferrules, and fibers, touched each other with the force of a spring, instead of the screw threads of the SMA. Japanese companies, in conjunction with NTT, developed a number of single fiber connectors that dominated communications fiber installations for decades, and still do: FC, SC and LC.
