Laser diodes in many cases are right modulated, that is the light-weight output is controlled by a existing used on to the gadget. For pretty significant info charges or very very long length links, a laser source could be operated ongoing wave, and The sunshine modulated by an external product, an optical modulator, including an electro-absorption modulator or Mach–Zehnder interferometer. Exterior modulation increases the achievable backlink length by removing laser chirp, which broadens the linewidth in directly modulated lasers, rising the chromatic dispersion in the fiber.
