Demonstrates Multivendor Operation at OFC 2025 Exhibition (Booth 2718).
Artificial intelligence is relentlessly driving data rates higher in computer systems. The higher rates are moving the crossover from copper to optical media to shorter distances including chip-to-chip and intrachip(on-chip) DPU, CPU, GPU and TPU or “xPU” links.
AIO Core, a supplier of silicon photonics transceiver Photonic Integrated Circuits (PICs), announced the first multivendor operation of 32Gbps transceivers for optical PCIe 5.0 for xPU links. The AIO Core optical engine incorporates quantum dot lasers and is designed for ultra-low power and small size transceivers. The novel AIO Core transceiver is a 5mmx5mm chip scale package operating in the 1300nm band. The use of quantum dot lasers enables the transceivers to operate at a wide temperature range (-40-+105C) with extremely high reliability.
“This product opens the door for multivendor interoperability in applications such as x4 PCIe 5.0 32Gbps multi-lane and higher rate xPU links with ultra-high spatial density”, said Mr. Kazuhiko Kurata, Chief Product Officer of AIO Core Co., Ltd. “The optical engine enables real application of silicon photonics for a wide temperature range for xPU links in next generation machine learning compute clusters that are
used for Large Language Models (LLMs) and other very large AI models”, he added.
“With our commitment to continuing innovation, I believe we will realize exceptionally low power dissipation for artificial intelligence xPU links in the near future”, said Mr. Hidetaka Fukuda, Chief Executive Officer of AIO Core Inc.
AIO Core is a startup company located in Tokyo dedicated to development of innovative high-speed silicon photonics optical engines for datacenter networks, HPC and other applications.
This demonstration is based on results obtained from a project, JPNP21029, commissioned by the New Energy and Industrial Technology Development Organization (NEDO), Japan.
