Keysight Technologies and Source Photonics Demonstrate Single-Wavelength 200G PAM4 EML Laser Performance

Keysight Technologies and Source Photonics Demonstrate Single-Wavelength 200G PAM4 EML Laser Performance

From March 6 to 9, 2023, Keysight Technologies, Inc. participated in the 48th OFC held in California, USA, an annual large-scale international conference and exhibition for optical communication professionals.

Keysight Technologies and Source Photonics collaborated to demonstrate the performance test of single-wavelength 200G PAM4 EML at booth 3029 at OFC2023. Keysight Technologies helped Source Photonics launch a single-wavelength 200G PAM4 EML laser that represents excellent performance. This type of product is a key core component for realizing 1.6T pluggable optical modules. This test was based on a test platform built with Keysight Technologies' M8199A arbitrary waveform generator and DCA-X N1032A sampling oscilloscope (Figure 1). The platform can provide 200Gb/s PAM4 signals and test the signal's optoelectronic eye diagram. Source Photonics' single-wavelength 200G PAM4 EML showed excellent optical eye diagram characteristics in this joint test (Figure 2), laying a solid foundation for the smooth development of subsequent 1.6T optical modules.

Dr. Joachim Peerlings, vice president and general manager of Keysight's Network and Data Center Solutions , said: "Keysight is pleased to provide industry-leading ultra-high bandwidth optical signal test solutions and demonstrate the readiness of 200G/λ technology with Source Photonics. 200G/λ is a key technology for next-generation 1.6T/3.2T data center applications. We are also proud to work with the world's top customers and help the world's leading optical communication technology innovators comprehensively solve various test challenges, enabling them to significantly shorten time to market and successfully launch products."

"We are pleased to collaborate with Keysight Technologies and demonstrate single-wavelength 200G PAM4 technology at OFC2023," said Frank Chang, CTO of Source Photonics . "We hope that this joint demonstration will accelerate the technical maturity of 1.6T pluggable optical modules and provide strong support for the mass deployment of 51.2T switches in data centers."
