Abstract
An apparatus for measuring the noise figure in optical amplifiers employed for large bandwidth applications such as dense wavelength division multiplexing systems. A booster amplifier coupled to a light source increases the average power associated with a plurality of optical channels. A periodic filter is coupled to the booster amplifier to reflect noise between each of the optical channels across the predetermined bandwidth. An amplifier under test is coupled to the periodic filter and the noise figure associated with the amplifier under test is measured.
