At ECOC 2026, which opened in Málaga, Spain, on September 21, Avicena demonstrated a MicroLED optical interconnect that can be disconnected and reconnected. The exhibition runs through September 23, and the company showed a live connectorized implementation of its LightBundle eKit at its booth.
LightBundle connects a MicroLED transmitter array and an integrated photodetector array through multicore optical fiber. This implementation inserts a detachable optical interface into the transmission path, allowing the connection to be separated and rejoined.
The on-site demonstration covered connector disconnection and reconnection, live data transmission after reconnection, parallel links through multicore fiber, and bit-error-rate monitoring. Compact fiber routing for space-constrained AI systems was also demonstrated.

Avicena said LightBundle uses MicroLEDs as light sources without lasers or optical modulators. It distributes data in parallel across hundreds of low-power optical channels to provide aggregate transmission bandwidth.
An earlier 1Tbps-class evaluation kit supplied by the company uses up to 335 independent MicroLED data channels, each operating at up to 3Gbps. The connectorized eKit adds a detachable interface to the same optical transmission architecture for assembly, independent testing and maintenance.
Target links within AI systems include XPU-to-XPU, XPU-to-memory, and network-interface-to-switch connections. Avicena also lists connections between packages, boards, trays and racks.
Dr. Choonghoon YI, CEO and Chief Analyst of UBI Research, said, “This is an example of MicroLED applications extending beyond displays to optical data transmission. The demonstration shows that connector reconnection and system assembly, as well as emitter performance, are becoming factors in commercialization.”
