InGaAs Photodiode Pigtail Manufacturers

This paper mainly introduces broadband light sources and its function.

Optical fiber temperature measurement technology is a new technology that has only been developed in recent years, and has gradually revealed some excellent characteristics. But just like other new technologies, optical fiber temperature measurement technology is not a panacea. It is not used to replace traditional methods, but to supplement and improve traditional temperature measurement methods. By giving full play to its strengths, new temperature measurement solutions and technical applications can be created.

Operators are making efforts to build 5G base stations, and the demand for optical modules continues to expand. In 2019, my country has built more than 130,000 5G base stations. 2020 is the first year of large-scale construction of 5G base stations, which mainly cover urban areas. In 2020, 5G network construction will focus on more SA networking, with higher commercial value. During the two sessions in 2020, the Ministry of Industry and Information Technology stated that my country added more than 10,000 base stations every week. According to the operator's investment plan, the three major operators will build 700,000 base stations in September 2020, and the construction will not stop from September to December. With China Radio and Television as a new entrant, the joint construction of 700MHZ 5G base stations with China Mobile is expected to be further expanded.

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".

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.
