The almond-colored thermoplastic housing mounts to a panel via flange or snap-in clips, and the simplex configuration supports a single-fiber channel. A dust cap is included to protect the alignment sleeves when the coupler is unmated. ## Panel Mounting and Dust Protection Mounting options include both a flange and snap-in clips, giving flexibility for different panel cutouts and thicknesses. The included dust cap keeps the internal alignment sleeves free of debris during storage or transport, which matters for maintaining low insertion loss on the first mate.","metaTitle":"TE Connectivity 1278017-1 MT-RJ Simplex Coupler, Multimode","metaDescription":"TE Connectivity 1278017-1 MT-RJ simplex coupler, multimode, almond housing.
