This fiber optic coupler is designed to connect two ST-simplex fiber optic connectors within a structured cabling environment in accordance with ISO IEC 11801. The coupler is an ST-simplex female to ST-simplex female adapter and is suitable for singlemode OS2 (9/125 µm) applications. The metal housing ensures mechanical stability and reliable mounting in panels with a D-hole cutout. The integrated ceramic alignment sleeve ensures precise alignment of the fiber cores and stable signal transmission. Mounting is via screw mounting with the included metric hex nut.
