800G optical module PCB - at present, the transmission rate of global optical network is rapidly moving from 100g to 200g / 400g. In 2019, ZTE, China Mobile and Huawei respectively verified in Guangdong Unicom that single carrier 600g can achieve 48tbit / s transmission capacity of single fiber.
The 200G optical module PCB is composed of shell, PCBA (PCB blank board + driver chip) and optical devices (dual fiber: Tosa, Rosa; single fiber: Bosa). In short, the function of the optical module is photoelectric conversion. The transmitter converts the electrical signal into the optical signal, and then the receiver converts the optical signal into the electrical signal after transmission through the optical fiber.
