Principle of Fiber Optic Lossless Splitter
At its core, a fiber optic splitter relies on the principles of light reflection, refraction, and waveguiding to divide signals. A fiber optic splitter is a passive optical component that divides a single incoming optical signal into two or more outgoing signals, or combines multiple incoming signals into one. They are devices that split an incident light beam into several light beams at certain splitting. Bandwidth is shared amongst customers in a PON, and the bandwidth received by a customer is not related to the power received at the optical network terminal (ONT) as long as the power is high enough so the ONT can operate. It plays a vital role in optical fiber communication systems, especially in passive optical networks (PONs).
