fiber fast connector

Updated on Sun Aug 24 2025

Fiber optic connectors are an essential component in modern optical communication systems, providing a quick and reliable way to connect and disconnect fibers. Among the various types of fiber optic connectors available, fiber fast connectors have become increasingly popular due to their ease of use and low cost. In this article, we will discuss the different types of fiber fast connectors and their features.


SC fast connector:

SC fast connector is a type of fiber fast connector that uses a push-pull coupling mechanism. It is one of the most popular fiber connectors used in fiber optic communication systems. The SC fast connector consists of a plastic or metal housing with a ceramic ferrule at the end, which holds the fiber in place. The connector can be terminated in the field using a specialized tool that cleaves and inserts the fiber into the connector.


LC fast connector:

LC fast connector is a small form factor (SFF) connector that is widely used in high-density fiber optic networks. The LC fast connector has a similar design to the SC connector but is smaller in size. It uses a 1.25 mm ceramic ferrule and a push-pull locking mechanism to ensure a secure connection. The LC fast connector is ideal for applications where space is limited, such as data centers and telecommunication systems.

ST fast connector:

ST fast connector is a type of fiber fast connector that uses a bayonet coupling mechanism. It is commonly used in data communications and telecommunication systems. The ST fast connector has a metal housing with a ceramic ferrule at the end that holds the fiber in place. The connector is terminated in the field using a specialized tool that cleaves and inserts the fiber into the connector.


FC fast connector:

FC fast connector is a type of fiber fast connector that uses a screw-on coupling mechanism. It is widely used in test and measurement applications and high-performance data communication systems. The FC fast connector has a metal housing with a ceramic ferrule at the end that holds the fiber in place. The connector is terminated in the field using a specialized tool that cleaves and inserts the fiber into the connector.


MTRJ fast connector:

MTRJ fast connector is a type of fiber fast connector that uses a dual-fiber ferrule design. It is widely used in fiber optic networks and is suitable for high-density applications. The MTRJ fast connector has a small form factor and is easy to install, making it an ideal choice for field termination. The connector uses a push-pull latching mechanism and is terminated using a specialized tool that cleaves and inserts the fiber into the connector.


E2000 fast connector:

E2000 fast connector is a type of fiber fast connector that uses a shuttered design to protect the fiber endface from contamination. It is commonly used in high-performance data communication systems and is ideal for applications that require a high level of reliability. The E2000 fast connector has a small form factor and is easy to install, making it an ideal choice for field termination. The connector uses a push-pull latching mechanism and is terminated using a specialized tool that cleaves and inserts the fiber into the connector.


In conclusion, fiber fast connectors offer a quick and easy way to terminate fibers in the field. They are available in a variety of types and are designed for different applications. SC, LC, ST, FC, MTRJ, and E2000 fast connectors are among the most popular types of fiber fast connectors available today. When selecting a fiber fast connector, it is important to consider the specific application requirements and choose the connector that best meets those needs.
