Which of the following connectors is known as the "stab-click" connector?

The SC Connector is often referred to as the "stab-click" connector due to its design and the way it operates. This connector features a push-pull coupling mechanism that allows for quick and easy installation or removal, producing a "click" sound when securely engaged. This click is a defining characteristic that helps technicians confirm that the connection has been made properly without the need for complex tools or additional equipment.

The design of the SC Connector aids in minimizing the risk of accidental disconnection and facilitates efficient installation, especially in applications that involve numerous fiber connections, such as data centers or telecommunication networks. The robust and user-friendly design of the SC Connector makes it a popular choice for both professional installations and everyday use in various AV applications.
