Overview of Fiber Optic Connector
Fiber optic connector is a device used to connect optical fibers, capable of transmitting and receiving optical signals. The design and performance of connectors directly affect the overall efficiency and reliability of fiber optic networks. With the demands of different application scenarios, various types of fiber connectors have emerged, playing a crucial role in modern optical communication networks.
Common Types of Fiber Optic Connectors
SC Fiber Optic Connector
SC fiber optic connector is one of the most commonly used types of fiber optic connectors, with a square shell design and a 2.5mm ceramic ferrule. Its push-pull latching structure makes connection and disconnection operations simple and fast, especially suitable for frequent use. SC connectors have excellent optical performance, low insertion loss, ensuring efficient data transmission and excellent signal quality. In addition, its high reliability makes it widely used in fields such as fiber optic communication networks and fiber to the home (FTTH), making it an ideal choice for fiber optic connections.
LC Fiber Optic Connector
LC fiber optic connector, also known as Lucent connector, is a small fiber optic connector with a 1.25mm ceramic ferrule. Compared to traditional SC connectors, its design has reduced the volume by about 50%, making it particularly suitable for high-density wiring environments and enabling more connections in limited spaces. LC fiber connector adopts a push-pull structure and is equipped with a latch lock design, ensuring convenient and fast connection and disconnection processes. Due to its compact appearance and excellent performance, LC connectors are widely used in fiber optic cabling and equipment connections in data centers, making them an ideal choice for efficient network architectures.
ST Fiber Optic Connector
ST fiber optic connector is an early type of fiber optic connector widely used in the field of fiber optic communication. It has a circular shell and a threaded interface design, which can be tightened by rotating the knob on the interface to effectively prevent loose connections. The main features of this connector include easy insertion and removal, simple structure, and relatively low cost, thus it has been widely used in early multimode fiber optic connections. The reliability and convenience of ST connectors make them still have certain application value in many network environments.
FC Fiber Optic Connector
FC fiber optic connectors, like ST connectors, belong to circular connectors. It adopts a screw-locked design, which fixes the connection through rotating the interface to ensure stable connection performance. FC connectors have excellent performance in stability and high reliability, suitable for various environments, mainly used for single-mode fiber connections, especially for high bandwidth and long-distance transmission applications. Its outstanding performance makes it widely used in fiber optic communication systems, ensuring signal quality and efficient data transmission.

Comparison of Connector Performance
Insertion Loss & Return Loss
Insertion loss and return loss are important indicators for evaluating the quality of connectors. In this regard, SC and LC connectors typically perform well and are suitable for high-speed data transmission and high demand network environments. FC connectors come second with higher stability and are suitable for high bandwidth and long-distance applications. Although the performance of ST connectors is relatively weak, they can still meet basic needs in many applications, especially in cost sensitive environments.
Durability
In terms of durability, FC connectors can provide high durability and stability due to their metal structure and screw buckle design. In contrast, SC and LC connectors are typically made of high-strength engineering plastics, ensuring good mechanical strength and ease of use. However, after prolonged use, the joints of these connectors may become loose, resulting in relatively poor durability. Although ST connectors also use metal structures, they are prone to breakage during use, resulting in poor durability.
Convenience
In terms of installation and maintenance convenience, SC and LC connectors, due to their push-pull design, make insertion and removal operations more convenient, allowing users to quickly connect and disconnect. In contrast, ST connectors require a half turn rotation for fixation after insertion, making their operation relatively complex. The FC connector adopts a threaded buckle design, which requires rotation for fixation during connection. Although it performs well in stability, its installation process is slightly more complicated compared to other types of connectors.
How to Choose the Right Fiber Connector
SC, LC, ST, and FC fiber optic connectors each have their own characteristics and are suitable for different application scenarios. When choosing a suitable fiber optic connector, comprehensive consideration should be given based on specific application requirements. For example, in high-density cabling environments, LC connectors may be the best choice due to their compact design; in applications that require high performance, SC or LC connectors are more ideal. For applications that require high stability, FC connectors provide better performance.
Therefore, when choosing a connector, one should weigh the installation environment, performance requirements, and budget to ensure that the selected optical connector can best meet the specific application requirements and achieve excellent network performance and reliability.
