What is a distinct characteristic of the ST connector?

The ST connector is known for its "stab and twist" connection method, which is a distinctive characteristic of its design. This connection technique involves pushing the connector into the port (the "stab" part) and then twisting a bayonet-style locking mechanism to secure it in place. This method provides a reliable physical and optical connection, which is essential in maintaining the integrity of data transmission over fiber optic lines.

In contrast, while the ST connector can be used in various applications, it is not specifically designed for high-frequency applications; other types of connectors might be more suited for those tasks. Although ST connectors are primarily used with fiber optic cables, stating that they can only connect to fiber cables is incorrect because certain types of connectors can also be adapted for other media. Lastly, the lightweight and portable nature of a connector does not specifically relate to the operational characteristics that define the ST connector. Thus, the distinctive “stab and twist” characteristic is what sets the ST connector apart in the realm of fiber optic connectivity.
