In recent years, the power density and thermal management challenges have increased exponentially due to the update and iteration of optical transceiver. Therefore, the influence of the operating temperature of the optical transceiver on the wavelength shift and the fluctuation of optical power makes major manufacturers put forward higher requirements for the temperature control of the transceiver. With its high temperature sensitivity, the DT series gold termination NTC chip can assist the optical transceiver for real-time temperature monitoring and become the core component of its temperature control system.

In optical transceiver, the gold termination NTC chip is usually installed on the surface of the optical laser heat sink or the cold end of the TEC, closer to the laser junction area for effective temperature control. Specifically:

1. Accurate temperature monitoring: The accuracy of EXSENSE Electronics’s gold termination NTC chip can reach ±0.5%, and the resistance drift rate is low, which can ensure that the temperature of the optical laser junction area is obtained more accurately and the stability of temperature measurement is maintained.

2. TEC closed-loop control: NTC will feed back the temperature signal to the optical laser control circuit, and adjust the TEC current through the algorithm to maintain the stability of the optical laser junction temperature. The NTC chip can effectively reduce the probability of wavelength shift and avoid abnormal conditions such as channel crosstalk.

3. Reduce the risk of power fluctuation: The temperature compensation through the gold termination NTC chip can stabilize the output power of the optical laser, avoid modulation distortion, and ensure the efficient and accurate reception of optical signals.

4. Rapid response: In order to cooperate with the evolution of optical transceiver in the direction of miniaturization, integration and high speed, the dimension of EXSENSE Electronics' gold termination NTC chip can reach 0.25mm*0.25mm, and the small dimension has higher sensitivity, which can speed up the entire temperature measurement process while saving assembly space, and provide more installation positions for other components of optical transceiver.

As the core component of optical transceiver temperature monitoring, the gold termination NTC chip effectively ensures the stable operation of optical transceiver in different temperature environments through the appropriate layout in the optical laser. With the continuous advancement of communication network construction and the continuous expansion of the scale of data centers, the excellent consistency, high sensitivity and great reliability of EXSENSE Electronics' gold termination NTC chip will also assist optical module in moving towards the goal of higher efficiency and lower power consumption.
