Fiber Amplifier

A fiber amplifier is a device that boosts the strength of light signals traveling through optical fibers, which are thin strands of glass or plastic used in telecommunications. By using a special type of material, often doped with rare earth elements like erbium, the amplifier amplifies the light without needing to convert it back into electricity. This process enhances signal quality and allows data to travel over long distances with minimal loss. Fiber amplifiers are crucial for modern communication networks, enabling faster internet speeds and clearer phone calls.
