A black box model (BBM) of common environment is introduced to characterize the gain of erbium-doped fiber amplifier (EDFA) for any wavelength in the range of 1540-1560 nm in the radiation environment. Two erbium-doped fibers with different concentrations have been radiated to confirm the validity of the BBM. Using the method of BBM, the less measured parameters can overcome the restriction of the measured time in radiation environment. Therefore, that affords a new way to characterize the gain deterioration characteristic of EDFA in multiwavelength in radiation environment.
