In data centers, optical modules exist everywhere, but few people mention them. In fact, optical modules are already the most widely used products in data centers. Today's data centers are basically optical fiber interconnection, and the situation of cable interconnection has become less and less. Therefore, without optical modules, data centers cannot operate at all. The optical module converts electrical signals into optical signals at the sending end through photoelectric conversion, and then transmits through optical fibers, and then converts the optical signals into electrical signals at the receiving end. That is to say, any optical module has two parts: transmitting and receiving. The function is to do photoelectric conversion and electro-optical conversion, so that the optical modules are inseparable from the equipment at both ends of the network. There are thousands of devices in a medium-sized data center.

The fiber optic current sensor is a smart grid device whose principle uses the Faraday effect of magneto-optical crystals.

DWDM(Dense Wavelength Division Multiplexing): is the ability to combine a group of optical wavelengths with a single optical fiber for transmission. This is a laser technology used to increase bandwidth on existing fiber optic backbone networks. More precisely, the technology is to multiplex the tight spectral spacing of a single fiber carrier in a specified fiber in order to utilize the achievable transmission performance (for example, to achieve the minimum degree of dispersion or attenuation). In this way, under a given information transmission capacity, the total number of optical fibers required can be reduced.

At present, China has become the world's largest manufacturing country, and the domestic market has an increasingly strong demand for laser technology products. Since 2010, thanks to the continuous expansion of the laser processing application market, China's laser industry has gradually entered a period of rapid development. In 2018, the scale of China's laser equipment market reached 60.5 billion yuan, a year-on-year increase of 22.22%, and the compound growth rate from 2011 to 2018 reached 26.45%. China Business Industry Research Institute predicts that China's laser equipment market will reach 98.8 billion yuan in 2021.
