While the two-level approach is common, more than two splitting levels, referred to as multi-level splitting, are possible in a cascaded system, with a variable overall split ratio such as 1x16 = 4x4, 1x32 = 4x8, or 1x64 = 4x4x4. A key challenge is determining how many users a single OLT port can support, which is defined by the split ratio. Traditional GPON networks often employ 1:32 or 1:64 splits, while XGS-PON allows higher ratios such as 1:128. However, higher splits reduce the power margin and limit reach, so. The two main types are PLC (Planar Lightwave Circuit) splitters and FBT (Fused Biconical Taper) splitters. PLC splitters: higher precision, good for large ratios (e., 1×32, 1×64 and beyond), uniform output, stable across temperature variations. 1 x Main FTTR can supports maximum 16 Sub FTTR. ATB (ATB2120-T-1-SA) + Transparent fiber (10m/20m/30m/100m). Here's a tabulated comparison of these two types: With the progressive growth of FTTH worldwide, the requirement for larger. For SME/industrial application larger split ratios (1:16, 1:32) and longer reach (1km) foreseen. Kai Habel Fibre to every room (FTTR) for WiFi 8 and.
