PAM4 Optical Transmitter Test Report

This presentation shows our recent test results of an eight wavelength 56G PAM4 configuration, transmitted on 10km G. The tests cover the following parameters to evaluate their effect on total system performance. Specifically, it focuses on performing transmitter measurements of PAM4 modulated signals, discussing some of the pros and cons of using sampling oscilloscopes vs. using real-time oscilloscopes in making PAM4 measurements in the. We distinguish the PAM4 bit rate from its symbol rate, refer ling, but the formal description is 2-level pulse amplitude modulation, or PAM2. At that meeting, we got a lot of quite helpful suggestions, based on which we carried out additional testing. [1-3] Although both signaling schemes use intensity modulation and direct detection, PAM4 encodes two bits into four intensity levels, reducing bandwidth. Testing 1.
