The TE Connectivity 2-2120871-1 is a duplex LC-to-LC singlemode fiber coupler in a blue housing. It converts from and to an LC Receptacle on both ends, making it a straight-through adapter panel for joining two LC-terminated simplex or duplex patch cords. The duplex format keeps both fibers of a transmit/receive pair in a single clip, which simplifies routing in patch panels and distribution frames. Mounting is via panel mount with flange and snap-in features — no separate hardware needed for a clean panel installation.
Lifecycle Status
