Laser diodes are sometimes immediately modulated, that is the light-weight output is controlled by a current applied straight to the system. For really higher data premiums or quite very long distance links, a laser supply could be operated continuous wave, and The sunshine modulated by an exterior system, an optical modulator, for instance an electro-absorption modulator or Mach–Zehnder interferometer. External modulation improves the achievable url length by reducing laser chirp, which broadens the linewidth in straight modulated lasers, expanding the chromatic dispersion while in the fiber.
