Optical Connectivity Innovations Shine Light on Scaling Up AI Networks at CIOE 2025

This year’s China International Optoelectronic Exposition (CIOE) in Shenzhen brought together thousands of global companies to showcase the latest breakthroughs in optoelectronics. One of the hottest topics on the show floor? Optical technologies powering the next wave of AI infrastructure.

For Credo, CIOE was a prime opportunity to demonstrate how its high-speed optical connectivity solutions are helping AI systems scale — faster and more efficiently.

Optical Connectivity: The Backbone of AI Compute Clusters

Training and inference for large-scale AI models demand massive processing power. To meet these requirements, compute clusters — made up of tightly coupled GPUs across multiple servers — must operate seamlessly as a unified system. This makes high-bandwidth, low-latency optical interconnects essential to avoid bottlenecks and maintain performance. At the heart of these interconnects are digital signal processors (DSPs), which ensure data integrity and enable higher data rates by encoding more information into the light signal.

A First at CIOE: Live Scale-Up Network Demo

One of the biggest draws at Credo’s booth was a live demonstration of a scale-up network — the first of its kind at CIOE — powered entirely by Credo DSP-based optics. The demo featured both single-mode and multi-mode transceivers, integrated with switches, servers and NICs from leading vendors, showcasing real-world performance and interoperability.

Introducing Bluebird: Credo’s 1.6T Optical DSP

Credo also unveiled its latest innovation: Bluebird, a next-generation optical DSP designed for 1.6T transceivers. Supporting 224Gbps per lane PAM4 transmission, Bluebird delivers breakthrough power efficiency, enabling transceivers to operate well below 20W — a critical advantage for AI data centers.

Optimized for GPU-to-GPU communications, Bluebird accelerates training and inference workloads, helping AI infrastructure scale with speed and efficiency.

Driving the Future of Optical AI Infrastructure

From deep technical discussions to high-energy demos, Credo’s presence at CIOE 2025 underscored its commitment to pushing the boundaries of performance, scalability, and innovation in optical connectivity.

As AI continues to evolve, Credo is helping build the infrastructure to support it — one optical link at a time.

If you missed us at CIOE, watch Chris Collins, VP of Product for DSP and Optical, discuss how Bluebird is scaling low-power, high-bandwidth, and ultra-low latency AI networks.

And, come visit Credo in booth C3432 at the European Conference on Optical Communication (ECOC) Exhibition taking place September 29 – October 1 in Copenhagen, Denmark.
