| What's the difference? Why would I choose one over the other? |

A little Googling and.... http://en.wikipedia.org/wiki/Optical_fiber_connector |

Yeah but that doesn't talk about the differences. Hardly mentions ST at all. ETA: damit, I searched... I didn't see ST in the chart. Missed it because it was combined with /BFOC. |

SC connectors are a push-in type connector like an ethernet connector. ST is a spring loaded twist-lock type connector. there is no difference in the fiber. ST is an older style and almost no manufacturers make ST based optics any more.
An easy way to remember which is which: ST = Slide / Twist SC - Slide / Click |

They are a positive lock connector and are still specified on every industrial project that we install fiber on. |

Quoted: Heh, I just bought cisco san switch modules to expand an old fiber channel array. It actually hurt me, I mean real physical pain, to quote them. Quoted: Use LC. Just about everything is LC these days , only things I use SC on anymore is old gear , and Cisco Xenpaks  and my patch panels are SC  It was that or redesign the DC for another rack. My boss is all about the band-aid right now. |

OP –– what is your application? do you have a piece of equipment in front of you that has terminations on it already, or are you looking to specify a connector for a project, or is this an educational exercise, or ...? that said, practically all modern single-mode fiber connections are made via LC. the ubiquity of modular SFP, SFP+, XFP, and now CFP (40Gbs/100Gbps) optics on both the client and line (DWDM) side has made the LC the de facto connector. ar-jedi <- DWDM equipment designer |
