GTC & OFC 2026 Day 1
The Beginning of the Optical Communication Supercycle

Jensen Huang: "$1 Trillion Through 2027"

NVIDIA CEO Jensen Huang announced at the San Jose SAP Center keynote that the combined order backlog for Blackwell and Vera Rubin reached $1 trillion (approximately 1,400 trillion won). This is a two-fold increase from the $500B forecast at GTC 2025. FACT

Vera Rubin GPU — The Heart of the Next-Generation AI Data Center

Vera Rubin NVL72 has been unveiled. It provides 5x inference performance compared to its predecessor with TSMC 3nm (N3P) process, 336B transistors, and sample shipments have already begun to customers. Full rollout is scheduled for H2 2026. Azure has completed its first hyperscale cloud power-up. FACT

Spectrum-X Photonics — World's First Mass-Produced CPO Switch

The core announcement in the optical communication sector at this GTC: Spectrum-X Photonics CPO Switch. 2Tb/s bandwidth per single port, 5x optical energy efficiency compared to pluggables, 10x network resilience, and 4x laser reduction. Confirmed real deployment in 10,000+ Blackwell Ultra GPU factories at Lambda — this is the world's first large-scale CPO deployment case. FACT

Key Partnerships & Product Announcements

Mega-deal signed with AWS to deploy 1M+ GPUs. $5B joint x86 processor investment with Intel. Groq 3 LPU (first chip after $17B acquisition) shipping in Q3 2026. NVLink Fusion licensing open (SiFive RISC-V first partner). Robot foundation model GR00T N2 and Disney Olaf robot demonstration. Four additional autonomous driving partners (BYD, Hyundai, Nissan, Geely) + Uber robotaxi partnership. FACT

GPU Roadmap: Vera Rubin → Feynman

Vera Rubin Ultra (144 GPU Kyber rack, built-in CPO optical interconnect) is scheduled for 2027, and the Feynman architecture is scheduled for 2028. The annual GPU cadence with a new architecture released every year has been officially confirmed. FACT

Largest Ever: 16,000 Attendees, 700+ Exhibitors, Sold Out

OFC 2026 (LA Convention Center, 3/15-19) opened as the largest ever. More than 16,000 registered attendees from 90 countries, with over 700 companies exhibiting — the exhibition hall is completely sold out. OFC has completely transformed from a traditional telecom conference to an AI infrastructure conference. FACT

1.6T Transceivers — First Year of Mass Production

Broadcom announced 400G/lane optical DSP technology, unveiling the core components of the 1.6T pluggable transceiver. Marvell expanded its 1.6T optical DSP portfolio and announced Aquila 1.6T + Ara 1.6T demonstrations and a keynote ("Building Optical Scale-up Networks for Next-gen AI"). FACT

Applied Optoelectronics (AAOI) demonstrated 1.6T and 6.4T onboard optics, CPO/NPO architecture readiness. Acacia (Cisco) unveiled the industry's first 800GZR+ interop PCS coherent pluggable. Hyper Photonix demonstrated a 1.6T SiP transceiver over 4-core multi-core fiber, and FIBERSTAMP demonstrated a 1.6T DR16-NPO silicon photonics engine. FACT

CPO — "Inevitable but Not Imminent"

Lightmatter unveiled near-package and CPO optical engines, and LightSpeed Photonics announced the industry's first solderable near-package optical interconnect. CEA-Leti + NcodiN announced that they will industrialize 300mm optical interposer technology through strategic collaboration. FACT

Cignal AI's assessment: "Inevitable but Not Imminent" — commercial trials in 2026, high-volume mass production after 2027. However, NVIDIA's Spectrum-X Photonics mass production deployment has the potential to accelerate this timeline. NARRATIVE

Plenary & Investor Events

Coherent CTO Julie Sheridan Eng presented market trends for lasers, modulators, transceivers, CPO, and optical circuit switches at the OFC plenary talk. Lumentum unveiled an OCS (Optical Circuit Switching) demonstration with Marvell at the 3/17 investor briefing — LITE stock +5.77%. FACT
