Abstract
A gain control arrangement for an optical amplifier for equalizing its amplification versus wavelength response at specific frequencies. A high loss attenuating fiber with reflective gratings to segregate undesired signals from wanted signals. Using either an optical circulator or a fused fiber splitter the gain control arrangement is coupled to the wide band output of an optical amplifier.
