100G PAM4 EML Chip of Zetta Semiconductor Passed Stringent Tests

Zetta Semiconductor, a leading supplier of optical communication technology in China, recently passed the third-party inspection by Pinghu Research Institute and released the data report of its self-developed and taped 100G PAM4 EML. The report shows that Zetta's 100G PAM4 EML has surpassed industry standards in several key performance indicators, fully demonstrating excellent signal quality and system fault tolerance.

In high-speed transmission applications, the bandwidth of the electro-absorption modulated laser (EML) is a key index to measure its performance. The 3dB bandwidth of Zetta's 100G PAM4 EML is above  53GHz within the operating temperature range, approaching the requirement for 200G bps EML (＞65GHz). This indicator not only meets the high standards of 100G bps EML but also indicates Zetta's technical potential in the field of 200G bps EML.

The report specifically mentions the TDECQ (Transmitter and Dispersion Eye Closure Quaternary for PAM4) test results of the product's PAM4 eye diagram. TDECQ is an important parameter for measuring the quality of PAM4 optical signals. The TDECQ values of Zetta's 100G EML are 1.89dB and 1.80dB under the conditions of 1.5 Vpp and 1.2 Vpp, respectively, both significantly lower than the 3.4dB required by IEEE standards, showing the significant advantages of Zetta's products in signal quality.

This breakthrough by Zetta Semiconductor is attributed to its profound technical accumulation and continuous innovation investment in the field of optical communication. The company stated that it is expected that the 100G PAM4 EML has started to deliver samples to a number of customers for verification and is expected to pass customer certification and enter mass production this year.

The progress of Zetta Semiconductor has not only brought new technological breakthroughs to the domestic optical communication industry but also injected new impetus into the development of global high-speed data transmission. With the rapid development of technologies such as 5G, data centers, cloud computing, and AI, Zetta Semiconductor is expected to occupy a more important position in the global optical communication market with its leading technologies and products.
