![]() Despite the additional complexity both in manufacturing and installation, the FC connectors still provide the choice in precision instruments such as OTDRs, as well as the choice for single mode fiber. The FC fiber optic connector end face relies on an alignment key for correct insertion and is then tightened into the adaptor/jack using a threaded collet. Unlike the plastic-bodied SC and LC connector, it utilizes a round screw-type fitment made from nickel-plated or stainless steel. FC fiber optic connector was the first optical fiber connector to use a ceramic ferrule. They are usually used in both long and short distance applications such as campuses and building multimode fiber applications, corporate network environments, as well as military applications. The ST optic connector holds the fiber with a ceramic, spring-loaded 2.5mm ferrule that stays in place with a half-twist bayonet mount. ST (Straight Tip) fiber optic connector was created and licensed by AT&T shortly after the arrival of the FC type. You can refer to our white paper Understanding Polarity in MTP/MPO System to have a better understanding. The MTP/MPO fiber connectors are complicated due to the key-up and key-down, male and female issues. It’s often used in 40G and 100G high-bandwidth optical parallel connections. Unlike the previous two fiber optic conneceors, the MTP/MPO fiber connector is a multi-fiber connector and larger than other connectors, which combines fibers from 12 to 24 fibers in a single rectangular ferrule. Due to its excellent performance, fiber optic SC connector remains the second most common connector for polarization maintaining applications. SC fiber optic connector is ideally suited for datacoms and telecom applications including point to point and passive optical networking. ![]() It adopts a 2.5mm ferrule, which is twice the size of the previous LC connector. “SC” stands for “Square Connector” due to the “square-shaped” connector body. SC fiber connector was the first connector chosen for the TIA-568 standard and is a snap-in connector that latches with a simple push-pull motion. LC fiber optic connector is considered the most commonly-used connector at present. Many tend to move to high-efficiency cabling with LC fiber connectors nowadays. The small footprint design gives these fiber optic connectors huge popularity in datacoms and makes them more ideal for high-density applications. ![]() LC ConnectorĪ Lucent Connector (LC), as one SFF (small form factor) connector, possesses a 1.25 mm ferrule. Fiber cables with these optical connector types are usually used in data centers, telecom rooms, enterprise networks and so on. The following fiber connector types, such as LC/SC/MTP/MPO/ST fiber optic connectors, require an adapter panel when connecting. Utilization: Fiber Connectors Connect with Adapter Panel Follow this article to classify fiber connector types. Generally speaking, different fiber cable connector types can be categorized according to different standards like the utilization, fiber count, fiber mode, transmission method, the transmission media, the boot length, the polishing type and the termination way, etc. Fiber optic connector that comes in various configurations and types is considered as an important component for the fiber optic cable.
