ABSTRACT:
A system and method to modify in real time the location of carriers in an optical fiber to avoid harmonic interference. Fiber means supply a spectrum of carrier wavelengths. Controller means sweep the entire spectrum of the carrier wavelengths for wanted and unwanted carrier wavelengths. Analyzer means plot wanted carrier signals versus unwanted signals in the spectrum. Control circuit means track the unwanted carrier signals; calculate the amount of spectrum that any or all of the carrier signals must move to avoid unwanted harmonics, and generate a control signal to change carrier frequencies of wanted carriers to avoid harmonics of unwanted carrier signals in the optical fiber.
