The TE Connectivity 1828074-1 is a duplex LC-to-LC multimode fiber optic coupler, designed for panel-mount installations where a clean, repeatable fiber connection is needed at a bulkhead or enclosure wall. It converts from an LC receptacle to an LC receptacle, so it functions as a pass-through adapter for two LC connectors — one on each side. The ceramic ferrule material is standard for multimode applications, providing stable insertion loss over repeated mating cycles. The red color is typical for multimode adapters, offering a quick visual identifier on a patch panel or distribution frame. A dust cap is included with the coupler, protecting the ferrule alignment sleeve from contamination when the port is not in use. The panel mount uses a snap-in retention feature — no additional hardware is needed beyond the panel cutout.
This coupler is fully compatible with standard LC connectors — both simplex and duplex plugs with a 1.25 mm ferrule will mate with the LC receptacles on either side. The duplex format means it aligns two fibers side-by-side in a single housing, matching the duplex LC connector interface common on SFP transceivers and patch cords. The panel mount snap-in design requires a rectangular cutout; the coupler snaps into place from the front of the panel. No screws or brackets are needed, which simplifies field installation or replacement on a patch panel.
