Which fiber optic connector is described as push-in and twist, used for single- and multi-mode cabling?

• A. ST Connector
• B. SC Connector
• C. LC Connector
• D. FC Connector

Answer: (A)

The idea being tested is a bayonet-style locking mechanism. The phrase “push in and twist” refers to how ST connectors lock: you insert the connector and then twist a short amount to lock it in place. That twist-lock keeps the connection secure and prevents it from backing out. ST connectors are designed for both single-mode and multimode fiber, which is why they’re described as usable with both types of cabling. They’re a common choice in older or enterprise networks because the bayonet coupling is fast to mate and unmate. Other connectors use different locking methods: SC uses a push-pull latch, FC is a screw-on threaded connection, and LC is a small form-factor connector with a different snap or latch mechanism. The push-in, twist-to-lock description specifically points to the ST connector.
