An optical splitter, also called a fiber optic coupler, splits an optical signal into multiple parts. It's a simple but effective way to distribute one input signal to various outputs without losing signal quality. Specifically, it functions as a power distribution device, capable of splitting an incident light beam into two or more beams, and vice versa. The fiber splitter optimally enhances. Whether you're a network engineer designing a PON (Passive Optical Network) or a homeowner curious about how your fiber connection works, understanding splitters is essential for grasping the backbone of modern connectivity.
