A technician is installing fiber patch cables in a dense data-center rack. The documentation specifies a small-form-factor duplex connector so each link can transmit and receive on separate strands while maximizing port density. Which connector type should the technician choose?
The Lucent connector (LC) is a small-form-factor fiber connector that uses a 1.25 mm ferrule and is available in a duplex clip that holds two fibers, providing bidirectional communication in half the panel space of SC or ST connectors. LC's compact size makes it the connector of choice in high-density environments such as switches, SFP/SFP+ transceivers, and patch panels. SC, ST, and MTRJ are also fiber connectors, but SC and ST are larger, and an MTRJ's duplex fibers are fixed in a single ferrule, making it less common in modern high-density racks.
