Laser diodes tend to be instantly modulated, that is the gentle output is controlled by a current applied straight to รังรอง the machine. For pretty significant data prices or very long length one-way links, a laser supply could possibly be operated steady wave, and the light modulated by an external machine, an optical modulator, for instance an electro-absorption modulator or Mach–Zehnder interferometer. Exterior modulation boosts the achievable backlink length by reducing laser chirp, which broadens the linewidth in right modulated lasers, escalating the chromatic dispersion within the fiber.
