The invention discloses a high-precision optical path debugging device and a debugging method thereof, wherein the device comprises a light source module and a receiving module, the light source module is used for providing reference light and receiving feedback signals. The invention discloses a high-precision optical path debugging device and a debugging method thereof, wherein the device comprises a light source module and a receiving module, the light source module is used for providing reference light and receiving feedback signals. These unassuming devices enable a single optical signal to be divided into multiple paths, making them indispensable for sharing network resources efficiently—from residential FTTH (Fiber-to-the-Home) connections to large-scale telecom backbones. This guide demystifies fiber optic splitters. Fiber optic splitter is a passive optical device used to distribute optical signals, which can divide input optical signals into multiple outputs to meet the fiber optic access needs of multiple terminal devices. Optical signals are comprised of photons and are much more complex than electrical signals.
