Global – October 19, 2026 -- Lightelligence has presented dOCS, an optical circuit switching (OCS) interconnect module that it says is built on the world's first silicon photonic OCS chip, aimed at AI clusters, GPU superclusters and high-performance computing (HPC) systems.
dOCS integrates optical switching into a QSFP-DD module
The module embeds switching directly in the interconnect. Signals can be routed through external optical ports or through internal cross-connections.
Lightelligence built the chip with its proprietary integrated photonic integrated circuit (PIC) technology. The built-in switching function links xPUs in a QSFP-DD form factor, which the company describes as deployment-friendly.
Lightelligence says dOCS eliminates the need for high-power top-of-rack switches
The company lists four product highlights: the silicon photonic OCS chip itself, significantly higher GPU utilization, removal of the high-power top-of-rack switch, and an open ecosystem.
Lightelligence says the architecture lets system designers build more resilient and serviceable optical fabrics and reduces network complexity in next-generation AI and HPC infrastructure.
The company describes its work as the development of a new paradigm for global optoelectronic hybrid computing.
