What type of connectors are commonly used for fiber optic cables?

The correct answer highlights the types of connectors that are specifically designed for use with fiber optic cables. SC, LC, ST, and MTP/MPO are all well-established connectors in the fiber optic networking field.

SC (Subscriber Connector) and LC (Lucent Connector) are widely used for their reliable performance and ease of use. Both types feature a push-pull locking mechanism that helps to ensure a secure connection and minimize signal loss. LC connectors are smaller than SC connectors, making them ideal for high-density applications.

ST (Straight Tip) connectors are another type of fiber optic connector that has been around for a long time. They feature a bayonet-style coupling mechanism which helps maintain a stable connection or improve durability in high-vibration environments.

MTP/MPO (Multi-fiber Termination Push-on/Multi-fiber Push-on) connectors are designed for high-density applications as well, allowing multiple fibers to be managed within a single connector. They are especially common in data center environments due to their ability to connect multiple fibers efficiently.

The other choices include connectors that are generally associated with copper cables (such as RJ45 for Ethernet and RJ11 for telephone) or connectors used for different signal types, which are not suited for fiber optic applications. Thus
