<P>PROBLEM TO BE SOLVED: To provide an optical amplifier apparatus, a method of controlling the same, and an optical transmission system, which use a simple method to correct an SRS tilt generated in a transmission path after a subsequent stage amplifier out of two amplifiers, which amplify an input optical signal in the previous stage and in the subsequent stage, in response to the frequency of the optical signal flowing in the transmission path. <P>SOLUTION: Control parameters for controlling two amplifiers and an attenuator are determined so as to correct a spectral slope caused by stimulated Raman scattering of an optical signal, based on network information received from another device. The two amplifiers and the attenuator are then controlled in accordance with the control parameters. <P>COPYRIGHT: (C)2011,JPO&INPIT |
