PLC planar waveguide Splitter, also known as optical coupler, is an integrated waveguide optical power distribution device based on quartz substrate. Like coaxial cable transmission system, optical network system also needs optical signal coupling, branching and distribution, which requires optical Splitter to realize. As one of the most important passive devices in optical fiber link, it is an optical fiber junction device with multiple input terminals and multiple output terminals, especially suitable for connecting local terminal and terminal devices in passive optical network (EPON, GPON, BPON, etc.) and realizing optical signal branch.

Pallet fiber splitter is the required specifications of PLC fiber splitter into the pallet structure, commonly used specifications are 1*16, 2*16, 1*32, 2*32 and 1*64.
