SC and LC connectors don't have anything to do with the signal. They are just different connector types, and both are used with single mode and multi mode fiber. APC (with SC or LC) connectors have angled ends to reduce the reflection of light causing signal degradation or interference. You don't want to connect an APC end with anything other than APC because they won't seat well and you'll get very bad signal if anything at all. Most other connector types are either specialized or legacy.
The diameter of the fiber however, is designed to carry different wavelengths of signal. Common fiber types are single mode and multimode. Single mode, which has a smaller diameter, is designed for longer distances, and multimode is common in data-centers etc. but I've seen single mode replacing multimode in a lot of cases due to costs coming down. There's actually two different diameters of multimode, and you never want to mix different fiber diameters. Larger diameter (multimode) fiber may carry a single mode signal in a pinch, but this is a hack, and performance may suffer. Even patching in fiber will ideally involve a microscope designed to inspect fiber and specialized cleaning tools since a small speck of dust or oil from your hand can completely disrupt the signal on glass with a diameter of 9 microns. Splicing or terminating fiber usually requires very expensive tools, and is careful work. So I've seen a lot of this stuff outsourced, even at large institutions. Fiber to residential homes is great, but I wouldn't recommend fiber inside a typical home.
