FBT Coupler is a passive optical device that achieves optical signal splitting, combining, or power distribution by melting and stretching multiple optical fibers at high temperatures after removing their coatings, forming a biconical structure. Its core features include low cost and customizable splitting ratio, making it widely used in PON networks and fiber optic sensors.
Common splitter modules include 1*4, 1*8, 1*16, 1*32, 1*64, 2*4, 2*8, 2*16, and 2*32. They are widely used in outdoor fiber optic distribution boxes for PON, FTTH, FTTX, and GOPN networks.
