Abstract:
A method for controlling performance of an optical amplifier, said method including the following steps:(i) obtaining value for input and output power electronic circuitry DC offset; (ii) specifying a desired control mode among at least two control modes; (iii) selecting required set point value; (iv) obtaining a required value and subtracting its corresponding DC offset to produce adjusted value; (v) obtaining control error signal by utilizing said adjusted value; (vi) subtracting said control error signal from any number to produce a controller input signal; (vii) transforming said controller input signal into digital representation of at least one control signal by a control algorithm; (viii) transforming said digital representation of said at least one control signal into at least one corresponding analog control signal; and (ix) applying said at least one analog control signal to at least one amplifier component via driver circuitry.
