It accepts LC connectors on both sides — same interface in and out — so it works as a feed-through adapter joining two LC-terminated cables or as a bulkhead pass-through on an enclosure wall. The coupler is rated for both Singlemode and Multimode fiber, which means it handles the full range of common telecom and datacom wavelengths without a mode-specific restriction; the zirconia ferrule alignment sleeve keeps core-to-core registration tight enough for singlemode tolerances. Mounting options include panel mount with flange or snap-in — the flange version uses screw holes for a secure fit on a flat panel, while the snap-in variant clips into a rectangular cutout for tool-less installation. The coupler ships with a dust cap and an integrated shutter. The dust cap protects the ferrule sleeve when no connector is inserted; the shutter closes automatically when the adapter is unmated, keeping dust and debris off the alignment sleeve in environments where the panel port is frequently swapped. The silver-coloured housing is standard for the 106127 series.","metaTitle":"Molex 1061271590 LC Duplex Fiber Coupler","metaDescription":"Molex 1061271590 LC duplex fiber optic coupler.
