Latvian PAM4 Optical Module
The optical modules leverage 200G PAM4 EML lasers around O band, including CWDM wavelengths of 1271nm/1291nm/1311nm/1331nm and LWDM wavelengths at 1295. 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. In this example, we use INTERCONNECT solutions to study the 4-Pulse Amplitude Modulation (PAM) format. MaxLinear's highly integrated PAM4 DSPs offer superior link-margin performance and low power to enable 100G, 400G, 800G, and 1. 6T modules connect a 16x100G host interface to 8x200G optics (16:8), next-generation designs will work with forthcoming 200G/lane switch ASICs, as shown in the top row of the figure. PAM4 modulation has transformed optical networking, but what exactly is it and how does it work? Traditionally, network engineers have relied on NRZ.
