The gold electrode NTC thermistor chip produced by EXSENSE Electronics Technology Co., Ltd. is high accuracy (can up to ±0.5%, ±1%, ±2%, ±3%), good heat-resistant circulation, stable performance and so on, and its operating temperature can reach more than 300℃.The minimum size of gold electrode thermistor chip can be 0.3*0.3mm, which is suitable for optical communication modules, special specifications can be customized according to customer requirements.

At present, optical fiber communication as the preferred information transmission medium, whether it is trunk network or access network, it has made rapid development. The popularity of optical communication is also due to its following advantages:

1, wide frequency band, large transmission capacity;

2, small loss, long relay distance;

3, light weight, small size;

4, great anti-electromagnetic interference performance;

5, small leakage, good confidentiality;

6, save metallic materials, conducive to the rational use of resources.

In the field of optical communication technology development and product development, high-end optical communication device technologies and products owned by Chinese enterprises with independent intellectual property rights have been widely used in optical networks, and the optical device industry has gradually shifted to China, which has become an important production and sales base of optical devices in the world. However, the industrial chain structure and the overall level of the industry is still a great gap with the international advanced level, far behind the European and American countries. Among them, the gap of chip technology is particularly obvious, high-end chip products are still monopolized by foreign enterprises.

In the telecommunications market, driven by 5G network construction, the global optical module market for wireless network applications is expected to reach us $790 million in 2020, with a year-on-year growth of 92.83%. China's network construction will be the main driving force. It is estimated that by the end of 2020, the total demand for 5G pre-transmission modules in China will be about 10.08 million (about 3 million in 2019), corresponding to a market size of $3.49 billion.

In the data center market, the 100G market is recovering with the recovery of capital expenditure, while the 400G commercial market is expected to continue to make breakthroughs this year. Combined with industry chain research and estimate, it is estimated that by the end of 2020, the global shipment of 100G optical modules will increase by 25% year on year, corresponding to 8.75 million units, and the decreasing amplitude of price is expected to be between 10% and 15% (the average price of 100G is about $150 in 2019); The 400G optical module is expected to be shipped in 500,000 to 800,000 units.

In optical communication, gold electrode NTC thermistor chip can play great role of temperature monitoring and temperature control. The high-accuracy NTC thermistor chip for optical communication module produced by EXSENSE Electronics Technology Co., Ltd., which has high stability and fast response speed, and is suitable for bonding of optical communication and laser module.
