Elinker talks about the Most Common Types of Fiber Optic Connectors

Each of the different types of fiber optic connectors offersits own advantages and disadvantages, and has its own specific applications to which it is best suited. Below is a list of some of the most common types of fiber optic connectors,Elinker will share their common uses, and the advantages they can bring to your fiber optic network with you.
SC
Though there are more varieties of fiber optic connector on the market than can be adequately discussed here, the number of fiber optic connectors you're likely to encounter in a professional setting are relatively few. SC fiber optic connectors are one of the most common types of connector used for commercial purposes and knowing about them will be essential for anyone working with a fiber optic network.
The one outstanding advantage of SC fiber optic connectors is their snap-in design. This design allows them to connect easily with other network implements. SC connectors have 2.5mm ferules and are well known for their reliable performance. Though they are typically simplex (unidirectional) in nature, SC connectors with duplex (bidirectional) formatting are available as well.
ST
ST fiber optic connectors have a 2.5mm ceramic ferrule, much like the SC fiber optic connector. However, whereas SC connectors mate via a snap-in mechanism, ST connectors use a spring-loaded cinch to couple with other network implements.
FC
Unlike the SC and ST connectors we just discussed, FC fiber optic connectors are typically used with singlemode fiber optic cables—cables that provide one propagation path along which information can travel. Singlemode fiber optic cables are typically used for cabling over longer distances than multimode fiber optic cables. Many datacom and telecom systems employ FC connectors for this purpose.
The FC fiber optic connector has a 2.5mm ceramic ferrule and effects its connections through a screw-type locking mechanism.
LC
With a size only half that of the SC, ST, and FC fiber optic connectors, the LC fiber optic connector is a good choice for cable terminations that need to be effected quickly and with little hassle. LC connectors have a 1.25mm ceramic ferrule and provide reliable performance for singlemode fiber optic cables. Many pieces of communications technology that require high-density connections—such as SFP and XFP transceivers—will employ LC fiber optic connectors.
The original intention of the Toslink connector was to form connections between CD players and home stereo systems. Today, Toslink connectors are used for connecting DVD players, Blu-Ray players, and video game consoles to digital stereo systems.
