400G OPTICAL TRANSCEIVER BASED ON PAM4 MODULATION

PAM4 modulation in optical modules

PAM4 is an optical modulation technique that allows for higher data rates and increased spectral efficiency compared to NRZ. In PAM4, each symbol represents multiple bits of information by varying the amplitude of the optical pulse to four distinct levels. PAM4 is a four-level pulse amplitude-modulated signal, which can be electrical or optical. In this example, you will learn how to: The system in this example contains the following elements: This page contains 2 sections. For three decades, non-return-to-zero (NRZ) modulation — representing one bit per transmitted symbol — was sufficient to carry each successive generation of Ethernet from 1 Gbps through to 25 Gbps per lane.

The switch supports data rates up to 200G (100 Gbaud PAM4) and eliminates the need for optical-electrical-optical conversion and optical transceivers, enabling lower power usage and improved throughput in high-bandwidth AI workloads. Jennifer Bernal, Kumarpal Mandoth Clocks and Timing Solutions ABSTRACT Hyperscale data centers and telecommunication market sectors are currently driving the need for high speed serial links using 112G and 224G Pulse Amplitude Modulation with 4-Levels Serializer and Deserializer (PAM4 SerDes). 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. A key new modulation scheme, PAM4, was introduced around 2017 and enabled the big jump from 100G to 400G. When it comes to enabling 400G and higher Ethernet speeds, a four-level pulse amplitude modulation or PAM4 multilevel signaling is needed as opposed to the non-return-to-zero (NRZ) modulation.
