Fiber optic connectors according to the connection: LC, SC, FC, ST, MU, MT, MPO/MTP, etc.; according to the fiber end face: FC, PC, UPC, APC.
LC connector
LC type connector (Lucent connector) is made of easy to operate modular jack (RJ) latch mechanism. LC connector using the size of the pin and sleeve is the general size of SC, FC, etc., the size of 1.25mm, so its appearance is only half the size of SC/FC.
SC connector
SC connector ('Subscriber Connector' or 'Standard Connector') connector is a snap-on standard square connector, fastening method is used to plug the pin latch type, no rotation. These connectors are made of engineering plastic and are inexpensive and easy to plug and unplug.
FC connector
FC fiber optic connectors (Ferrule Connector) and SC connectors are the same size, the difference is that FC is the use of metal sleeves, fastening method for the screw fastening. Simple structure, easy to operate, easy to make, durable, and can be used in high vibration environment.
ST Connector
ST fiber optic connector (Straight Tip) has a round shell, using 2.5mm ring plastic or metal shell, fastening method is screw fastening, commonly used in fiber optic wiring frame.
MTP/MPO connectors
The MTP/MPO connector is a special type of multi-fiber connector with a complex structure that connects 12 or 24 fibers in a rectangular fiber insert. It is usually used in high-density connection scenarios, such as data centers, etc.
In addition to the above, connector types include MU connectors, MT connectors, MTRJ connectors, E2000 connectors, etc. SC is probably the most commonly used fiber optic connector today, mainly due to its low cost design. lc fiber optic connector is also a commonly used fiber optic connector, especially for connecting to SFP and SFP+ fiber transceivers. fc is mostly used for single mode, and is less common in in multimode fiber. ST fiber optic connectors are typically used for long and short distance applications such as campus and building multimode fiber applications, enterprise network environments and military applications.
