At its core, an FBT splitter operates on the principle of fused biconical tapering, a process where two or more optical fibers are fused together and stretched under controlled heat, creating a tapered interaction region that couples light evanescently between the cores. Bandwidth is shared amongst customers in a PON, and the bandwidth received by a customer is not related to the power received at the optical network terminal (ONT) as long as the power is high enough so the ONT can operate. Splits are most commonly factors of 2, such as 1x2, 1x4, 1x8, 1x16, 1x32. A fiber splitters is an optical device that can distribute optical signals from one optical fiber input to multiple output ports. It plays a vital role in optical fiber communication systems, especially in passive optical networks (PONs).
