Working principle of 200G optical module

The working principle of 200G optical module mainly includes the conversion of electrical signal to optical signal, modulation and transmission of optical signal, and conversion of optical signal to electrical signal. Specifically, 200G optical module converts electrical signal into optical signal of specific wavelength through electrical-optical conversion device. These optical signals are modulated and transmitted through optical fiber. After reaching the receiving end, the optical signal is converted back into electrical signal through photoelectric detection device.
