Crystal oscillator is one of the most popular components used in electronics, like phone, computer and micro-controller. They are a type of electronic circuit that produces a periodic signal with a frequency determined by its quartz crystal or metal-oxide-semiconductor (MOS) device.
The optical module is one of the core devices of the optical communication system, and its development has a vital impact on its related industrial chain. So, what is an optical module? How to upgrade the upstream industry PCB of optical modules? And what are the main applications of optical modules?
The PCB industry has developed so far, and its application fields cover communications, data centers and servers, consumer electronics, automotive electronics, energy and power, industrial control, medical care, aerospace and defense, and many other fields. The development of the PCB industry is closely related to the development of downstream industries.
