Which connector type is described as push-in and twist/set-and-twist/straight tip and is used in both single- and multi-mode cabling?

Which connector type is described as push-in and twist/set-and-twist/straight tip and is used in both single- and multi-mode cabling?

• A. ST Connector
• B. SC Connector
• C. LC Connector
• D. MT-RJ Connector

Answer: (A)

The key idea is recognizing fiber optic connectors by their coupling method and name. The description “push-in and twist/set-and-twist” points to a bayonet-style locking that you twist to secure, and the term “straight tip” is literally part of the connector’s name. That combination fits the ST connector, which is designed for both single-mode and multimode fiber services and uses a bayonet twist to lock after a push-in insertion. Other options use different locking or form-factor styles: SC is a push-pull type, LC is a small form factor with a latch, and MT-RJ is a duplex connector with a different rectangular ferrule design.
