Which connector type uses a retaining tab that must be pressed to remove a faulty fiber optic network cable?

The LC connector type uses a retaining tab that must be pressed to remove the connector from its port. This design provides a secure connection and helps maintain the integrity of the optical signal, minimizing the potential for accidental disconnections. The tab needs to be pressed to release the connector, which ensures that there is a clear mechanism in place to identify and avoid unintentional removal, especially in high-density applications where multiple fibers may be present.

In contrast, other connector types, while they may have their own unique features, do not utilize a retaining tab design like the LC connector. SC connectors, for example, utilize a push-pull design that doesn’t require pressing a tab for removal, and MTP connectors are typically used for multi-fiber applications with a different form factor. ST connectors feature a bayonet coupling mechanism, which involves twisting to lock and release rather than pressing a tab. Each of these connectors serves specific applications and environments, but the LC’s design is notable for requiring a retaining tab for secure connection.
