This connector shares a round profile like the ST connectors we reviewed but instead of coming equipped with a spring-loaded twist lock mechanism, this connector has a threaded connection. The FC connector also utilizes a 2.5mm ferrule. The main disadvantage of and SC connector is although its square body is easier to insert/take out, the body is larger than the LC connector which means it will take up more room than its newer cousin.SC connectors are perfectly suited for datacoms and telecoms.Sometimes there just is not enough room for the pull and twist connectors and that is where the SC connector becomes a life saver. The square shape of these connectors offers a more compact design which in turn means that more of these connectors can be installed in a smaller footprint of a space.An SC connector can alleviate these problems. Sometimes with the ST connectors, when they are pulled back, the spring mechanism will slam the fibers together. This ensures that the signal is not to be interrupted. This term means that once the connector has been installed, any pushing or pulling on the jacket of the cable will not cause the ferrule to disconnect, which is a prevalent problem with the ST model connectors. The SC connector is what is called a non-optical disconnect connector.Similar to the ST connector, this SC style also utilizes a 2.5mm ferrule. The SC connector was invented to directly replace the ST connectors and, as a result, has become one of the most common fiber connectors in the world. If there is a tray with lots of connections this can get tedious as it may become hard to get into the tight spaces to decouple/recouple the connectors. Also, with this being a spring-loaded connection, the installers must push the connector with quite a bit of force and turn the nut to use these connectors. ST Connectors have a round shape to them and are not as compact as more modern square body connections.This connector has a keyed “slot” on the end of the connector that helps keep it tightly mated to the fibers and in alignment when they are decoupled and recoupled. The ST connector, while older, is still commonly in use in today’s fiber installations due to it being extremely easy to install and its relatively low cost compared to some other connectors.This is an older style connector but is still commonly used in multimode applications. These connectors use a 2.5mm ferrule that is mounted on the inside of the housing. We will also touch upon the MTP/MPO connections.
