Classified by Package Style
The optical splitter can be terminated with different forms of connectors, and the primary package could be box type or stainless tube type. Fiber optic splitter box is usually used with 2mm or 3mm outer diameter cable, while the other is normally used in combination with 0.9mm outer diameter cables. Besides, it has variously different split configurations, such as 1x2, 1x8, 2x32, 2x64, etc.
Classified by Transmission Medium
According to the different transmission mediums, there are single mode optical splitter and multimode optical splitter. The multimode optical splitter implies that the fiber is optimized for 850nm and 1310nm operation, whereas the single mode one means that the fiber is optimized for 1310nm and 1550nm operation. Besides, based on working wavelength differences, there are single window and dual window optical splitters—the former is to use one working wavelength, while the latter fiber optic splitter is with two working wavelengths.
Classified by Manufacturing Technique
FBT splitter is based on traditional technology to weld several fibers together from the side of the fiber, featuring lower costs. PLC splitter is based on planar lightwave circuit technology, which is available in a variety of split ratios, including 1:4, 1:8, 1:16, 1:32, 1:64, etc, and can be divided into several types such as bare PLC splitter, blockless PLC splitter, ABS splitter, LGX box splitter, fanout PLC splitter, mini plug-in type PLC splitter, etc.
Normally speaking, the FBT splitters provide cost-effective solutions while the PLC splitters suit for high-density applications. The following chart has summarized several factors comparing between PLC splitter and FBT splitter.
Type | PLC Splitter | FBT Coupler Splitters |
---|---|---|
Operating Wavelength | 1260nm-1650nm (full wavelength) | 850nm, 1310nm, 1490nm and 1550nm |
Splitter Ratios | Equal splitter ratios for all branches | Splitter ratios can be customized |
Performance | Good for all splits, high level of reliability and stability | Up to 1:8 (can be larger with higher failure rate) |
Input/Output | One or two inputs with an output maximum of 64 fibers | One or two inputs with an output maximum of 32 fibers |
Housing | Bare, Blockless, ABS module, LGX Box, Mini Plug-in Type, 1U Rack Mount | Bare, Blockless, ABS module |
