Abstract:
An optical fiber amplifier comprising:(A) an optical system including: (i) an optical gain medium; (ii) at least one pump source coupled to the optical gain medium; (iii) an input port for an in-coming signal; (iv) an output port for an out-going signal; (v) an input optical signal tap coupled to a first optical detector; (vi) an output optical signal tap coupled to a second optical detector; and (B) an electronic controller adapted to utilize inputs received from said detectors to control optical power provided by said pump source, said controller including a programmed unit and a user interface that allows a user to chose between at least two functions to control at least one of the following available functions: desired amplifier gain value, amplifier output power value, DC off-set calibration, and ASE noise compensation.
