Optical communication is the foundation of the Internet economy. In the past decade, the Internet industry has shifted to the mobile Internet era. Huawei, Cisco, Ericsson, ZTE, Alcatel and other equipment manufacturers have become leaders in the optical communications industry.
With the development of optical communication technology, equipment manufacturers have begun to get involved in the field of optical device. Today's optical communications market is becoming more and more fierce, the communication equipment requires a smaller and smaller volume, and interface board includes the interface of the density is higher and higher.
In order to meet the requirements of optical devices for communication devices, optical modules are being developed toward highly integrated small packages. Highly integrated optoelectronic modules allow users to deal with high-speed analog optoelectronic signals, shorten research and development and production cycles, and reduce the types and production costs of vital components. Therefore, they are increasingly favored by equipment manufacturers.
For example, optics used in smartphones or portable power supplies.
When you use a smartphone or mobile power, do you feel it hot?
In fact, the smart phone is a small, powerful small computer. But because the mobile phone is not equipped with a computer cooling fan, the body becomes hot. Because the precision parts inside the mobile phone are sensitive to the heat generated, there is a danger of damage. At this time, the internal temperature of the smartphone is measured using a negative temperature coefficient (NTC) thermistor or NTC chip, and then temperature information is used to control the temperature.
Exsense Electronic Technology Co., Ltd. is a manufacturer specializing in NTC chip thermistors. NTC chip has high precision, good stability and high reliability. In general, optical communication uses the NTC chip thermistor to measure temperature. Optical communication with NTC chip size is 0.3*0.3mm, the resistance is 10KΩ, and the B value is 3935KΩ.
Our newly developed gold electrode NTC thermistor chip for an optical communication module has better chip stability than a silver electrode chip, and does not experience silver migration under high temperature conditions. It is suitable for bonding of optical communication and laser modules. To know more information of NTC thermal chip, NTC thermistor, please refer: http://www.exsense.cn/products/
