Optical PAM4 transceiver
The two cascaded phase modulator in each branch modulates the NRZ electrical signal to a four phase fixed power optical signal; when combined by the coupler, the output signal is with four different
What is PAM4 Modulation and How is it Transforming Optical
In this blog, we take a higher-level look at PAM4, the modulation scheme that makes short distance 400G networking possible, and discuss how this technology will shape the future of optical
