1st-order Raman spectroscopy utilizes stimulated Raman scattering in silica optical fibers. 140 nm pump light directly amplifies C-band signal light (1530-1565 nm). The pump light vibrates and scatters in the fiber, transferring energy to the frequency of the signal light.

​Optical amplifiers are mainly divided into three categories: erbium-doped fiber amplifiers, semiconductor optical amplifiers, and Raman optical amplifiers. Each amplifier has its own advantages and is used in different fields in optical communication systems.

With the explosive growth in AI computing power demand, ultra- high- speed optical modules such as 800G and 1.6T have become core equipment for data center interconnection and cloud network construction. LAN- WDM DFB fiber- coupled lasers, as the core light source at the module's transmitter end, are perfectly compatible with high-speed optical modules such as 800G/1.6T/400G due to their multi- wavelength characteristics and high linearity.

Thermistors are mainly used for temperature monitoring, overheating protection, etc. It is a temperature-sensitive semiconductor resistor whose resistance changes significantly with changes in temperature. It uses the heat-sensitive effect of semiconductor materials to measure and control temperature, and is widely used in various electronic devices and systems. Thermistors have the advantages of small size, fast response speed, and high measurement accuracy. Therefore, they have been widely used in temperature measurement, temperature control, overcurrent protection and other fields. Text symbols are generally represented by "RT".
