What is the difference between fiber SC and LC?

　　Fiber SC and LC are two different types of fiber optic connectors, and they have obvious differences in interface design, connection method, size and application scenarios. The following is a specific comparative analysis:

　　Interface design

　　SC interface:

　　The full name is Subscriber Connector, and it is sometimes referred to as Square Connector because of its unique square design.

　　The interface shell is rectangular and has a relatively simple structure.

　　The interface color is usually blue for high recognition.

　　LC interface:

　　The full name is Lucent Connector, developed by Lucent Technologies.

　　The interface design is compact, with a size of about 1.25mm, which is about half smaller than traditional SC or FC connectors.

　　The interface color is also usually blue, but it is smaller in size than the SC interface.

　　Connection method

　　SC interface:

　　It is directly plugged and plugged into the SC coupler without rotation.

　　The push-pull locking mechanism makes connection and disconnection easy and fast.

　　LC interface:

　　Made with easy-to-operate modular jack (RJ) latch mechanism.

　　The mating method is similar to the SC interface, but it is smaller, allowing for high-density connections in a limited space.

　　III. Dimensions and application scenarios

　　SC interface:

　　The size is relatively large, but it still has a wide range of application scenarios.

　　It is often used for fiber optic connections of network devices such as routers, switches, and servers.

　　It is widely used in data centers, local area networks, metropolitan area networks, and various optical fiber communication networks.

　　LC interface:

　　Compact size allows for high-density connections.

　　It is often used to connect SFP fiber optic modules and is suitable for applications that require a large number of fiber optic connections.

　　It has been widely used in data centers, telecommunications networks, enterprise networks, and other fields.

　　IV. Other differences

　　Compatibility: The SC interface supports multimode fiber and single mode fiber, and is suitable for various fiber communication standards. The LC interface also has good compatibility, but is more commonly used to connect SFP modules.

　　Cost: The structure of the SC interface is relatively simple and the manufacturing cost is low, so the equipment and maintenance cost of the SC interface are more advantageous when deploying a large number of optical networks. Although the LC interface is small in size, it may be slightly more expensive because of its more complicated manufacturing process.

　　To sum up, there are obvious differences between fiber SC and LC in terms of interface design, connection method, size and application scenario. Which connector type to choose depends on the specific use requirements and environmental conditions.
