SUNNYVALE, Calif. — Avicena, the pioneer in microLED-based optical interconnects, today announced that it has begun shipping 1 Tbps LightBundle™ evaluation kits (eKits) to customers and partners developing next-generation AI infrastructure. The shipment milestone follows the introduction and demonstration of the LightBundle eKit in March 2026 at the Optical Fiber Conference (OFC26) and advances the platform from initial evaluation availability to terabit-class operation in customer laboratories.

The latest LightBundle eKit incorporates a 335-channel microLED array, with each microLED data channel operating up to 3 Gbps, coupled with an Avicena multicore fiber bundle to a 335-element integrated photodiode array. Together, the channels provide up to 1Tbps of aggregate raw throughput displaying the core advantages of Avicena’s laser-free optical architecture: low power, high bandwidth density, robust operation at elevated temperatures, and flexible reach beyond the practical limits of copper interconnects.

A Terabit-Class Platform for AI Connectivity
Article content
AI systems are driving rapid increases in the bandwidth required between accelerators, memory, and switch fabrics. As link rates rise, copper interconnects face increasing challenges in reach, routing density, and energy efficiency. Conventional optical solutions based on lasers and silicon photonics can extend reach, but have power, bandwidth density, cost, and reliability challenges.
Article content
Avicena’s LightBundle technology replaces lasers with dense microLED transmitter arrays coupled through a multi-core fiber bundle to integrated photodetector arrays. This architecture is designed to deliver high bandwidth density and energy-efficient optical connectivity while operating reliably across demanding system temperatures.
Article content
The 1 Tbps eKit gives engineering teams a complete platform for evaluating link behavior in their own laboratories. Host interface boards, integrated diagnostics, and a graphical user interface support a set of features, including characterization of optical signal integrity, link budgets, eye quality, crosstalk, power efficiency, and bit error rate performance.
Article content
“Shipping our 1 Tbps LightBundle™ eKits extends Avicena’s microLED-based optical interconnect leadership and represents a significant milestone in delivering the terabit-class connectivity required to scale next-generation AI infrastructure,” said Marco Chisari, CEO of Avicena. “LightBundle addresses the bandwidth density, power, reliability, reach and cost requirements that are critical for scale-in and scale-up links, such as XPU-to-XPU, XPU-to-memory, XPU-to-CPU and XPU-to-switch connectivity.”
