Abstract
A dual fiber optic amplifier uses a single pump source for two or more optical power amplifiers. The dual fiber optic amplifier includes a pump source that emits light, a pump splitter, a first optical power amplifier and a second optical power amplifier. The pump splitter splits the light emitted by the pump source into two or more portions. The first optical power amplifier includes an optical fiber input, an optical fiber output, and a doped fiber portion, wherein the first portion of light from the splitter is coupled into the optical fiber input of the first optical power amplifier. The second optical power amplifier includes an optical fiber input, an optical fiber output, and a doped fiber portion, wherein the second portion of light emitted from the splitter is coupled into the optical fiber input of the second optical power amplifier.
