The IP67 rating — Dust Tight, Waterproof — means this adapter seals at the bulkhead when mated, so a splice closure or outdoor patch panel stays dry even in a rain splash or washdown environment. Singlemode operation keeps insertion loss low over long spans; the ceramic ferrule aligns the 9/125 µm cores repeatably. Panel mount, bulkhead style — it clips into a rectangular cutout and seals against the panel face with the included gasket. ## What the IP67 Rating Means for Field Fit An IP67 rating on a fiber coupler is not just a spec-sheet checkbox — it tells you the adapter has a compression gasket that seals the panel opening and the mating LC connectors lock into the bore with a positive detent. Hand-tighten the coupling nut on the LC connector until it clicks; that click confirms the O-ring inside the adapter bore is compressed. A half-turn loose is a dropout path for moisture. For outdoor cabinets, wall penetrations, or washdown food-processing lines, this coupler keeps the fiber termination dry without a secondary boot or potting. ## Mating and Termination Check Both ends of this coupler are LC Receptacle — it accepts a standard LC connector on either side. No SC, no ST, no FC compatibility; it is LC-to-LC only. The duplex format means two fibers (transmit and receive) pass through a single cutout, which halves the panel space compared to two simplex adapters. The ceramic ferrule sleeves are split-sleeve type, so the alignment is self-centering each time you insert a connector.","metaTitle":"Amphenol CONEC 17-300230 Duplex LC Coupler, Singlemode, IP67","metaDescription":"17-300230 Amphenol CONEC duplex LC-to-LC singlemode coupler.
