Optical Splitter Assembly Dimensions and Price

Optical splitter assemblies vary in size and price depending on type, fiber count, and packaging, with typical dimensions ranging from compact 1x2 or 1x3 modules to larger PLC splitter modules, and prices starting from tens to hundreds of dollars per unit.Dimensions and Types1. Fused Biconical Taper (FBT) SplittersCompact packaging, often used for 1x2, 1x3, or 1xN configurations.Fiber core sizes typically 200–250 µm, with lengths around 2 meters for standard assemblies (Ocean Optics SPLIT200-UV-VIS) .Low insertion loss (~1 dB for 1x3 splitters) and low polarization sensitivity .Dimensions are small and mechanically stable, often integrated into protective housings for spectroscopic or network applications . 2. Planar Lightwave Circuit (PLC) SplittersIdeal for high fiber counts (1x4, 1x8, 1x16, 1x32, 1x64).Compact, flat modules with broad wavelength bandwidth (±200 nm).Fixed uniform splitting ratios; custom ratios possible at higher setup costs .Can be packaged in bare fiber, connectorized modules, or inside/outside plant enclosures . 3. Micro-Optic CouplersUse lensed fiber collimators with optical elements.Ultra-broad bandwidth, high polarization extinction ratio, and excellent thermal stability.Slightly larger than FBT splitters due to integrated optical elements . Connector OptionsLC, LC/APC, SC, SC/APC, FC, FC/APC, or connectorless configurations.Fiber jackets: 900 µm loose tube or 250 µm bare fiber .Price RangeFBT splitters: Typically start around $20–$50 for small 1x2 or 1x3 units, depending on fiber type and connectors .PLC splitters: Prices vary widely based on fiber count and packaging; small 1x4 modules may start around $50–$100, while high-count 1x32 or 1x64 modules can cost several hundred dollars per unit .Custom or high-power splitters (fusion or micro-optic) may exceed $500, especially for specialized wavelength ranges or high-temperature operation .SummaryOptical splitter assemblies are available in FBT, PLC, and micro-optic types, with dimensions ranging from compact 1x2/1x3 modules to larger multi-fiber PLC modules. Prices depend on split ratio, fiber type, connectorization, and packaging, with FBT splitters being the most cost-effective for small-scale applications and PLC splitters preferred for high-count, broadband, or network deployments. Customization is widely available for both dimensions and performance specifications .
