Fiber optic communication systems require light sources to convert electrical signals into optical signals for transmission. The most commonly used light sources are LEDs and laser diodes. LEDs are typically used in short-distance, low-speed systems due to their broad spectral width and lower cost, while laser diodes are preferred for long-distance, high-speed transmission because of their high intensity, narrow spectral width, and coherent output .
In fiber optic communication, LEDs are cost-effective for short-range applications, while laser diodes (F-P, DFB, VCSEL) dominate long-distance, high-speed systems. Broadband sources and rare-earth-doped fiber lasers are specialized options for high-performance networks, with material choice and wavelength selection critical for minimizing loss and dispersion .
