In recent years, 5G mobile communication technology has gradually matured, and the improvement of communication speed and communication capacity have made optical transmission systems widely used, which also opened up the sales of optical transceiver. In order to ensure the stability of data transmission and optimize the internal heat dissipation components of the optical transceiver, NTC thermistor chip is usually placed for temperature monitoring.
In the working process of the optical transceiver, it is necessary to ensure that its operating temperature is kept in a certain range (generally ≤ 70 ℃) to output a laser with a stable wavelength and complete the transmission and reception of data transmission. The use of NTC thermistor chip to monitor real-time temperature can reduce the fluctuation of the operating temperature and ambient temperature of the optical transceiver and maintain its normal operation.
Gold electrode NTC thermistor chip developed and produced by EXSENSE is small in size and can be customized in size, which can meet the narrow installation space of optical transceiver and meet different assembly positions of customers; Both surfaces of the semiconductor ceramic are coated with gold electrodes, so that its consistency is better and more stable than that of the silver electrode NTC thermistor chip; Its high-precision characteristics make the temperature measurement process more accurate. Gold electrode NTC thermistor chip is suitable for the bonding process, which is more cost-effective and has more installation flexibility than the SMT process.
