Insights into Fiber Connectors

SC Connectors: The SC (Subscriber Connector) is known for its easy push-pull design, making it user-friendly. Its larger ferrule size allows for better alignment and lower insertion loss, making it suitable for various applications.
LC Connectors: The LC (Lucent Connector) is a small form factor connector ideal for high-density applications. With a ferrule half the size of SC connectors, it is commonly used in data centers and telecommunication networks.
FC Connectors: The FC (Ferrule Connector) features a screw-on mechanism, ensuring a secure connection. It is widely used in high-precision applications, such as testing and laboratory environments, due to its low insertion loss and high durability.

ST Connectors: The ST (Straight Tip) connector utilizes a bayonet-style locking mechanism, making it easy to connect and disconnect. It is often used in legacy systems but is gradually being replaced by more efficient designs.
