With the rapid development of 5G communications, AI computing power, etc., optical transceivers in data center need to handle higher capacity and faster data transmission. During this process, the junction temperature of the optical transceiver and the ambient temperature around it will continue to rise. To suppress the impact of temperature on optical transmission performance, EXSENSE gold termination NTC chip is placed in optical transceiver as temperature feedback component to reduce data transmission anomalies caused by temperature issues.

By monitoring the internal temperature of optical transceiver in real time, the NTC chip can provide accurate temperature data, thereby ensuring that the optical transceiver operates stably within an appropriate temperature range. When the temperature changes, the resistance value of the EXSENSE gold termination bare chip changes exponentially. By monitoring changes in the resistance value, the ADC can convert it into temperature data, providing informational support for temperature monitoring of optical transceiver. In addition, the NTC chip works in collaboration with other components such as TEC to balance the operating temperature of the optical transceiver. When a temperature rise approaching the critical value is detected, the MCU sends a command to the TEC to initiate cooling and lower the temperature. With the aid of the gold termination NTC chip, the optical transceiver can operate normally under different ambient temperatures, reducing the impact of temperature on data transmission accuracy.

1. High accuracy: EXSENSE optical transceiver NTC chip has a resistance value/Beta value tolerance of ±1%, meaning it is more sensitive to temperature changes and can accurately detect tiny temperature fluctuations. Based on the temperature values obtained from the gold termination bare chip, the optical transceiver can adjust the junction temperature more promptly, reducing performance fluctuations caused by uneven temperatures and ensuring stable operation of optical communication system.

2. Small dimension: The dimension of EXSENSE optical transceiver NTC chips can reach 0.21mm×0.21mm, aiming to achieve miniaturized packaging of optical transceiver. In situations with limited internal space in the optical transceiver, the small-dimension bare chip saves considerable internal space, facilitates rational arrangement with other components, improves internal space utilization, and helps optimize the overall structural design of the optical transceiver.

3. Weatherability: The EXSENSE bare chip features gold terminations coated on both the upper and lower surfaces of semiconductor ceramic material, allowing it to maintain stable electrical performance even under complex conditions such as high temperature and high humidity, ensuring normal temperature monitoring inside optical transceiver.

As the core temperature monitoring component of optical transceiver, EXSENSE gold termination NTC chip, with its excellent sensitivity to temperature changes, capture internal temperature fluctuations in real time and provide a solid data foundation for subsequent temperature control. Furthermore, the collaboration between EXSENSE gold termination optical transceiver NTC chip and other components enables precise temperature regulation within the optical transceiver, ensuring stable operation under various environmental conditions and significantly improving its anti-interference capability and stability.
