MicroLED Rides Optical Comm Fast Lane

🔑 Enhanced Key Takeaways

• •Avicena launched the world's first MicroLED optical interconnect evaluation kit, LightBundle™ eKit, demonstrating 512 Gbps links with 320 microLED channels at up to 3.5 Gbps each.
• •MediaTek developed a MicroLED-based Active Optical Cable (AOC) supporting 800G and 1.6T speeds for short-reach (<100m) AI data center interconnects, reducing power by 20-30% vs. copper cabling.
• •Microsoft's MOSAIC project and TSMC's efforts promote MicroLED in 'Wide and Slow' architectures using parallel low-speed channels for energy-efficient, scalable AI optical interconnects.
• •Mojo Vision and Marvell are jointly developing MicroLED solutions for various AI data center interconnect form factors targeting hyperscale applications.

🛠️ Technical Deep Dive

• •MicroLED optical modules support linear bandwidth scaling via multi-channel expansion (e.g., 800G to 3.2T) and single-channel rate increases, compatible with OSFP/QSFP interfaces, PCIe, Ethernet, InfiniBand, NVLink, CXL.
• •Avicena's LightBundle™ eKit features 320 active microLED channels (plus 64 spares) at 3.5 Gbps/channel for 512 Gbps total, enabling terabit-per-mm bandwidth density without lasers.
• •MediaTek's AOC uses proprietary MicroLED arrays instead of VCSELs, optimized for <100m in-rack links with 20-30% lower power than active electrical copper cables.
• •MOSAIC employs 'Wide and Slow' (WaS) architecture with hundreds of parallel low-speed MicroLED channels, contrasting 'Narrow and Fast' (NaF) laser models for better efficiency and reliability.
