A technician is terminating fiber patch cables for a data-center switch. The infrastructure standards call for a small-form-factor duplex connector so transmit and receive fibers can be plugged into adjacent ports while maximizing panel density. Which connector should the technician install?
Straight tip (ST)
Lucent connector (LC)
Subscriber connector (SC)
RJ45
The Lucent connector (LC) is a small-form-factor fiber connector that uses a 1.25 mm ferrule and is commonly supplied as a duplex assembly, allowing separate transmit and receive fibers in a single clip. Its compact size lets installers place dozens of duplex ports in limited rack space, making it the preferred choice in high-density data centers. SC and ST are larger or simplex fiber connectors, and RJ45 terminates copper twisted-pair cable rather than fiber.
