800G OSFP active electrical cable solution

Description - 202610S1

Reliable 800G short-reach copper connectivity for AI, HPC and cloud data centers

This 800G Active Electrical Cable (AEC) solution is based on Marvell PAM4 DSP Retimer technology and is designed for short-reach, high-speed interconnects in AI servers, high-performance computing systems and cloud data centers. By integrating a DSP/Retimer into the cable assembly, the solution provides retiming, equalization and compensation for high-speed PAM4 signals, helping extend copper cable reach and improve link stability. It supports 112G PAM4 SerDes and the OSFP interconnect form factor.
