摘要
The present invention relates to use the identical gain flattening method for using a doped fiber amplifier (EDFA) of a short-period fiber bragg grating center wavelength and the flat EDFA of a gain. ;Optical communication system transitional information is transferred to a modulated optical signal, by fiber optic transmission optical signal, then transmitting photo-signal on the contrary. Doped fiber amplifier is inserted into the light path to compensate light loss. Pass through execution, the gain spectrum of EDFA can be crushed in a desired wavelength bandwidth to be obtained using one the flattening of short-term optical fiber grid, its a desired wavelength can arbitrarily adjust one wish transmission device spectrum as an optical filter, it is effective, can be improved.
