Home / Why do fiber optic cables need to be connected to optical modules
Optical modules serve as the "translators" of fiber-optic networks, enabling seamless electrical-to-optical (E/O) and optical-to-electrical (O/E) conversion. Fiber-optic communication is a form of optical communication for transmitting information from one place to another by sending pulses of infrared or visible light through an optical fiber. The light is a form of carrier wave that is modulated to carry information. Its primary function is to achieve optoelectronic conversion by converting electrical signals into optical signals and vice versa. In optical fiber communication, metal wires are preferred for transmission because the signals travel more safely.
