PAM4 Icelandic Optical Receiver
Here, we report the demonstration of a single chip optical WDM PAM4 receiver, where by co-integration of a 32-channel optical demultiplexer (O-DeMux) with autonomous wavelength tuning and locking at a near-zero power consumption and a 32-channel ultra-low power concurrent. The Marvell® PAM4 optical DSP portfolio, including Spica™ and Nova™ DSPs, addresses the critical the need for high-bandwidth optical interconnects to power AI infrastructure. Marvell leads the pluggable module ecosystem with low-power, high-performance silicon for AI, cloud, enterprise and 5G. ) Thanks!This paper presents a low noise 28 Gbaud/s linear receiver front-end for fourth-order pulse amplitude modulation (PAM4) signal applied in the field of optical communication. Since PAM4 signal do not return-to-zero after each symbol, they are also an NRZ signaling scheme.
