In the field of optical communications, long-distance transmission has long been challenged by issues such as signal attenuation and distortion. Raman fiber amplifiers, with their unique advantages, have become a key technology for improving the performance of long-distance optical communication systems.

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.

Semiconductor lasers are a type of lasers that mature earlier and are developing rapidly. Because of its wide wavelength range, simple manufacture, low cost, easy mass production, and because of its small size, light weight, and long life, its variety develops quickly and its application The range is wide, and there are currently more than 300 species.
