Which are common types of fiber optic connectors?

The correct response identifies SC, LC, ST, and MTP/MPO as common types of fiber optic connectors, which is accurate because these are widely used standards for connecting fiber optic cables.

SC (Subscriber Connector) is a popular type that allows for quick connections and disconnections and is known for its push-pull design, facilitating easy handling. LC (Lucent Connector) is a small form-factor connector, favored for high-density applications due to its compact size. ST (Straight Tip) connectors are also common, utilizing a bayonet-style coupling that provides a secure connection for multimode fiber applications. MTP/MPO (Multifiber Termination Push-On/Pull-Off) connectors are designed for high-density environments, capable of handling multiple fibers within a single connector, which makes them essential in modern fiber optic installations where space and efficiency are paramount.

The other options listed connectors typically used for electrical connections or different types of cables rather than fiber optics, making them less relevant in the context of fiber optic installations.
