What is the primary locking mechanism used by the Straight Tip (ST) fiber optic connector?

The primary locking mechanism used by the Straight Tip (ST) fiber optic connector is the push-and-twist method. This design allows for a secure connection where the connector is inserted into the port and then twisted to lock it into place. This mechanism ensures a reliable physical connection and optimal alignment of the fiber optic strands.

The push-and-twist feature is beneficial because it provides a firm and consistent coupling that minimizes the likelihood of disconnection due to vibrations or movement. This is particularly important in environments where fiber optic installations may be subjected to physical stress.

In contrast, other locking mechanisms like twist-and-lock, slide-and-lock, or snap-fit do not specifically describe the operational technique of the ST connector, which relies on the simultaneous action of pushing the connector into the port and twisting to secure it firmly.
