Alphawave Semi Brings Next-Generation Connectivity and Compute Innovations to ECOC 2025

Showcasing 224G XLR SerDes, 1.6T Multi-Standard I/O Chiplets, 36G UCIe D2D IP Subsystem, and 800G/1.6T PAM4 & Coherent-lite DSPs.

LONDON, United Kingdom, and TORONTO, Canada – September 29, 2025 - Alphawave Semi (LSE: AWE), a global leader in high-speed connectivity and compute silicon for the world’s technology infrastructure, will showcase the latest advances in AI and connectivity IP at the European Conference on Optical Communication (ECOC) 2025.

Taking place this year at the Bella Center in Copenhagen, Denmark, ECOC is Europe’s leading optical communications conference, bringing together experts from academia, research, and industry. Building on the company’s previously announced DSP launch at OFC, Alphawave Semi continues to expand its leadership in high-performance connectivity. Its comprehensive portfolio enables high-speed communications across both electrical and optical channels, extending distances of up to 20 km. This innovation is underpinned by Alphawave Semi’s cutting-edge PAM4 SerDes, the differentiated WidEye™ DSP technology and EyeQ™ advanced diagnostics technology—all designed to address the scale and performance demands of hyperscalers deploying accelerated AI compute infrastructure.

At the event, Alphawave Semi will also showcase a broad range of solutions, including:

• Cu-Wave™ PAM4 DSP for Active Electrical Cables (AEC)
• O-Wave™ PAM4 DSP for Optical Retimer and Gearbox Transceivers
• Co-Wave™ Coherent-lite DSP for Optical Transceivers

Together, these solutions highlight Alphawave Semi’s commitment to delivering silicon-proven, production-ready technologies that enable the next generation of AI, cloud, and high-performance computing platforms.

Attendees will also have the opportunity to meet with the Alphawave Semi team to learn more about the company’s latest innovations, including:

• 224G PAM4 Electrical SerDes
   224G XLR IP subsystem solutions unlocking the next generation of high-speed connectivity.
• 1.6T I/O Chiplets
