SC Connector (Subscriber Connector/Square Connector)

First up, we have the SC connector, which stands for Subscriber Connector or sometimes Square Connector. This is one of the most popular types, known for its simple push-pull design. The SC connector is a versatile connector, widely used in various applications, including telecommunications, data communications, and CATV (Cable Television) systems. Its ease of use and reliability have made it a favorite among installers and network administrators. The SC connector uses a 2.5mm ferrule, which is the part that holds the fiber in place and ensures precise alignment. This connector also has a rectangular shape, which makes it easy to identify and handle. Because of its sturdy design, the SC connector can withstand a lot of use and still provide a reliable connection. Its widespread use makes it easily available and compatible with a wide range of equipment.

FC Connector (Ferrule Connector/Fiber Connector)

Next, we have the FC connector, which stands for Ferrule Connector or sometimes Fiber Connector. This connector is characterized by its threaded body, which provides a secure and reliable connection. This type is commonly used in high-vibration environments and precision applications. The FC connector is known for its durability and is often used in applications where a stable and precise connection is required. The threaded body of the FC connector ensures a firm connection, which prevents it from accidentally disconnecting. The FC connector's design is very robust, making it suitable for industrial and scientific applications. Typically, the FC connector uses a 2.5mm ferrule, similar to the SC connector. This type is particularly well-suited for single-mode fiber applications and offers good performance. Though less common than the SC connector, the FC connector is still a reliable choice for applications requiring a secure, vibration-resistant connection.

LC Connector (Lucent Connector/Little Connector)

Last, but not least, we have the LC connector, often referred to as Lucent Connector or Little Connector. This is a small form factor connector, meaning it's smaller than the SC or FC connectors. The LC connector is increasingly popular, especially in high-density applications where space is at a premium. Its compact size allows for more connectors to be packed into a single panel. The LC connector uses a 1.25mm ferrule, which is smaller than the 2.5mm ferrules used in SC and FC connectors. This smaller ferrule size is one of the reasons for its compact design. This connector also features a simple push-pull design, similar to the SC connector, making it easy to install and use. Given its small size and high performance, the LC connector is a top pick for modern networking applications, including data centers, and is a favorite for high-speed networks and equipment where space is at a premium.
