2020/04/30 03:04:17



EXSENSE Electronic Technology Co., Ltd., adopts advanced semiconductor process, combines with independent intellectual property rights, through high-precision material processing, slicing, packaging and testing equipment imported from Japan, Taiwan, Germany, to achieve high-precision, mass production of high-reliability NTC gold-electrode reliability chip. NTC gold electrode thermistor chip produced and developed by EXSENSE Electronics, which is suitable for optical communication module, special specifications can be customized according to customer requirements.


Optical communication is a way of transmitting information using optical and optical fibers. The rapid development of optical communication has brought great changes to the global communication industry, which has become the most important mode of wired communication. Optical communication is widely used in telephone, Internet and cable TV signals due to its advantages of large transmission capacity and good confidentiality. Optical communications will also interact with communication technologies such as Wi-Fi and cellular networks (3G, 4G, and even 5G), bringing innovative applications and valued experiences in areas such as the Internet of Things, smart cities (homes), aviation, navigation, subways, high-speed rail, indoor navigation, and underground operations.


The resistance value of the NTC gold-electrode thermistor chip decreases as the temperature increases, and vice versa. This feature makes NTC gold electrode chips commonly used in temperature monitoring, temperature control and temperature compensation.


And the working principle of optical communication is, at first the information to be transmitted is converted into an electrical signal at the sending end, then modulated to a laser beam emitted by the optical maser, make the light intensity changes over the frequency of the signal, and sent to the receiver through the optical fiber, finally, the detector at the receiving end receives the optical signal, converts it into an electrical signal, and then recovers the original information after demodulation. The optical maser is the most important part of optical communication, and the laser diode is the core part of the laser head, which has the characteristics of small size, light weight and low power consumption. However, it is very sensitive to overcurrent, overvoltage and electrostatic interference, in use, the temperature increment of laser diode will increase the value of the current flowing through it, therefore, must adopt the necessary cooling measures. At this time, the NTC gold-electrode thermistor chip can play the role of temperature detection, in order to ensure that the laser diode in the appropriate temperature range, to avoid the temperature is too high, leading to accidents.


NTC gold-electrode thermistor chip with high accuracy (accuracy can up to ±0.5%, ±1%, ±2%, ±3%), great reliability, high sensitivity, rapid response and so on, its operating temperature can up to 300℃, which is suitable for TO-CAN and other encapsulated forms, as well as bonding, welding.
