IBM has unveiled an advanced optical technology that promises to transform data center operations, bringing unprecedented speed and energy efficiency to the training and execution of generative AI models. The innovation involves the use of co-packaged optics (CPO), which is set to replace traditional electrical interconnects.

Key Points:

• Co-packaged optics promise connectivity at the speed of light, overcoming the limitations of electrical connections.
• The new technology reduces energy consumption and significantly accelerates the training of AI models.
• IBM’s innovation enables up to 80 times greater bandwidth compared to current solutions.
• The optical modules have been designed to withstand extreme conditions, ensuring robustness and reliability.

Co-packaged optics represents a quantum leap in data center communications, integrating the use of light to transfer data instead of electricity. While external data center networks have already adopted fiber optics to transport data over long distances, inside the racks, most connections still use copper electrical cables. This system leads to significant inefficiencies, such as GPUs sitting idle for long periods waiting for data, increasing costs and energy consumption.

IBM has unveiled a prototype that uses a polymer optical waveguide (PWG), demonstrating how optics can enhance internal data center communications, increasing bandwidth and dramatically reducing downtime. This innovation promises dramatic benefits: up to a five-fold acceleration in AI model training times, energy savings that could reduce the consumption of more than 5,000 American homes per trained model, and a dramatic extension of cable lengths up to hundreds of meters while maintaining terabit data transmission.

At the heart of this technology is the ability to employ multiple wavelengths per optical channel, enabling unprecedented bandwidth density. IBM researchers have developed modules with a channel pitch of just 50 micrometers, improving the density of optical fibers per chip by six times compared to existing technology. The fibers, three times thinner than a human hair, can span variable distances and withstand stress tests in harsh environments, demonstrating high robustness.

With these advances, IBM is not only taking AI scalability to new heights, but also strengthening its leadership position in semiconductor innovation. The company has already achieved significant milestones, such as creating 2-nanometer chips with more than 50 billion transistors and pioneering process technologies. With the support of its advanced facilities in Albany and Bromont, IBM continues to set new technology standards.

Optical co-packaging is a critical step toward addressing the growing performance and sustainability demands of data centers, paving the way for a future where speed, efficiency, and innovation seamlessly converge.
