A method includes modulating a laser that is coupled to a fiber, modulating the laser with a member selected from the group consisting of low frequency thermal modulation or bias modulation to broaden a laser linewidth, increase an SBS threshold and reduce an IIN, and modulating the laser with a predistorting modulation selected from the group consisting of phase modulation or amplitude modulation, the predistorting modulation being of equal magnitude but opposite phase as that produced in at least one member selected from the group consisting of the laser or the fiber as a result of the low frequency thermal modulation or bias modulation An apparatus includes a laser, and a fiber coupled to the laser, wherein the laser is i) modulated ii) modulated with a member selected from the group consisting of low frequency thermal modulation or bias modulation to broaden a laser linewidth, increase an SBS threshold and reduce an IIN and iii) modulated with a predistorting modulation selected from the group consisting of phase modulation or amplitude modulation, the predistorting modulation being of equal magnitude but opposite phase as that produced in at least one member selected from the group consisting of the laser or the fiber as a result of the low frequency thermal modulation or bias modulation
