Which type of connectors are commonly used with optical fiber cables?

SC, LC, and ST connectors are standard types specifically designed for use with optical fiber cables.

The SC (Subscriber Connector) is popular for its ease of use and durability, featuring a push-pull mechanism that makes it user-friendly and reliable. The LC (Lucent Connector), is smaller and often preferred for high-density applications, utilizing a latch mechanism similar to that of the SC, which helps maintain a secure connection. ST (Straight Tip) connectors are also widely recognized and utilize a bayonet-style coupling, making them easy to connect in various settings, particularly in enterprise networks.

These connectors are designed to minimize loss and back reflection, which is essential in fiber optic applications where light signal integrity is critical for performance over long distances.

In contrast, other options listed do not serve the same purpose; RJ-45, USB, and HDMI are primarily used for electrical connections, while BNC and F-connectors are typically utilized for coaxial cables. Type-A and Type-B connectors are generally associated with USB interfaces, which again are not applicable to fiber optics.
