Which connector is similar to the BNC connector and can be used on both multimode and single-mode fiber-optic cable?

The ST connector is a type of fiber-optic connector that is commonly used in networking applications. It features a push-and-turn mechanism for secure connections, which is similar to the locking mechanism of a BNC connector used in coaxial cabling. This design helps ensure a reliable connection that minimizes the risk of disconnection.

The ST connector can be utilized with both multimode and single-mode fiber-optic cables, making it versatile for various applications in fiber networks. Its construction allows for easy termination and is widely adopted in environments where robustness and ease of use are needed, similar to the characteristics that make BNC connectors prevalent in RF applications.

In contrast, other options like the LC and SC connectors have different designs and locking mechanisms, focusing on compactness and density in fiber management, primarily suited for single-mode applications, though they also accommodate multimode. The MTP connector, being a higher-density solution, is typically associated with parallel optics and has a different use case compared to the ST connector. Thus, the ST connector aligns closely with both the mechanical properties of BNC connectors and the application needs across fiber types.
