Both ends are LC receptacle interfaces, so it couples two LC connectors directly — no adapter conversion. The beige housing signals multimode compatibility per TIA-568 color coding; this coupler will not work with singlemode fiber without significant insertion loss. Mounting is via a panel flange with snap-in retention — drops into a rectangular cutout and locks without hardware. The duplex configuration routes two fibers (Tx and Rx) through a single housing, common in duplex patch panels.","metaTitle":"TE 3-2120871-1 LC Duplex Multimode Fiber Coupler, Obsolete","metaDescription":"TE Connectivity 3-2120871-1 LC duplex multimode fiber coupler, panel mount with flange.
