An optical add/drop device, an optical add/drop system, and method thereof is provided herein. The optical add/drop system may include, a first variable coupler which splits input light to through light and dropped light, a wavelength blocker which attenuates an intensity of each channel of the through light, a second variable coupler which couples the through light from the wavelength blocker and added light, and a dropped light detector which measures an intensity of the dropped light. Further, the system may include an added light detector which measures an intensity of the added light, a through light detector which measures an intensity of the each channel of the through light from the wavelength blocker, and a controller which controls the first variable coupler, controls the wavelength, and controls the second variable coupler.
