Two major uses of photodetectors in optical communication systems

Two major uses of photodetectors in optical communication systems

Photoelectric detection and optical receiver   At the transmitting end of the optical fiber communication system, the light source is modulated with a low-frequency baseband electrical signal, and then the modulated light signal is transmitted via the optical fiber. Due to factors such as attenuation and dispersion
