The performance stability of optical transceiver responsible for high-speed data transmission in data center directly affects its own transmission rate. If the junction temperature of the optical transceiver or the ambient temperature is abnormal, it will lead to problems such as decreased working reliability, wavelength drift of the internal laser output, etc. To avoid the aforementioned technical troubles, EXSENSE recommends embedding the DT series gold termination NTC chip in optical transceiver to monitor the working temperature of it in real time, ensuring its normal operation.

Compared to traditional NTC chip, what outstanding characteristics enable EXSENSE gold termination NTC chip to stand out and efficiently temperature monitor in optical transceiver, making it the "guardian" of its stable operation?

1.Small dimension fits the integration needs of optical transceiver

The gold termination NTC chip independently developed and produced by EXSENSE can reach a size of 0.21mm × 0.21mm, which better supports the compact packaging space of optical transceiver compared to traditional large-sized NTC chip, avoiding the occupation of limited layout resources. Additionally, the small dimension NTC chip has more excellent sensitivity, responding faster when the optical transceiver is working, shortens temperature monitoring times and provides better temperature protection effects.

2.High accuracy ensures stable temperature control of optical transceiver

The accuracy of the EXSENSE gold termination NTC chip can reach ±1%, ±0.5%. By working in conjunction with the TEC inside the optical transceiver, it ensures precise quantification of the transceiver's junction temperature while efficiently achieving temperature control, thus improving the transceiver's performance stability. Moreover, due to the high accuracy characteristics of the gold termination NTC, it can help correct the junction temperature of the optical transceiver, ensuring stable operation under various working conditions.

3.Wide temperature range supports long-term high-load operation of optical transceiver

The working environment of optical transceiver is extreme harsh, ranging from urban areas and forests to deserts and glaciers. The temperature resistance range of EXSENSE gold termination NTC is from -55℃ to 300℃, which is significantly wider than that of conventional NTC chip (-40℃ to 125℃), which can better meet the temperature monitoring requirements of optical transceiver in various complex environments.

EXSENSE DT series gold termination NTC chip, as the core component for temperature monitoring in optical transceiver, effectively reduces the probability of performance degradation caused by abnormal temperatures through its excellent electrical performance. Moreover, the small dimension, high accuracy and wide temperature range characteristics of the gold termination NTC chip further promote the miniaturization, high-density integration, and high-speed development of optical transceiver, helping product upgrade of optical transceiver.
