Simplex fiber optic adapters connect one fiber strand, while duplex adapters connect two fiber strands in a paired configuration. Choose the format that matches the cable and equipment, with simplex options suited to single-fiber connections and duplex options suited to paired transmit-and-receive links.

Match the adapter’s fiber mode to the cable: use single-mode adapters for OS1, OS2, or 9/125 µm fiber, and multimode adapters for OM2, OM3, OM4, or 50/125 µm fiber. Then match the connector type, such as LC or SC, and the connection style, such as simplex or duplex, to the equipment and enclosure.

Check the connector type, fiber mode, port count, and whether the plate fits your enclosure or patch panel, such as an LGX-118-compatible panel or a compatible fiber enclosure. Also confirm the plate’s physical dimensions and configuration, including LC or SC ports and single-mode or multimode support, before installation.

Fiber optic adapters support capacity expansion by adding simplex or duplex LC and SC connections within adapter plates, panels, and terminal boxes. Push-in plates with configurations for six, 12, or 24 fibers let installers add ports as the structured cabling system grows while supporting single-mode or multimode fiber.
