Which of the following connector types is a small-form-factor device with a 1.25 mm ceramic ferrule that is used to terminate single-mode or multimode fiber-optic cables and is commonly found on SFP transceivers and high-density patch panels?
RJ45
LC
F-type
BNC
The LC (Lucent Connector) is specifically designed for optical fiber. Its push-pull latch, compact size, and 1.25 mm ferrule make it ideal for high-density fiber applications such as SFP/SFP+ transceivers and data-center patch panels. RJ45 and BNC are copper/electrical connectors, while F-type is used for coaxial cable in RF applications. Therefore, LC is the correct choice.
