Berlin, August 2025 – VI Systems GmbH announces the acquisition of several key patents to accelerate the development of 200G and 400G short-reach optical interconnects for AI compute clusters and Ethernet networks.

Market demand for high-speed optical links

The growing adoption of artificial intelligence requires ever faster and more efficient data center connectivity. Industry experts highlight the need for 200G per lane short-reach solutions, where power efficiency and cost are critical.

In response, on August 1st, 2025, the IEEE initiated the 802.3 200Gb/s per wavelength MMF PHYs Study Group, with a dedicated Task Force expected to launch in January 2026. In parallel, the IEEE “Ethernet for AI” assessment group is exploring 400G per wavelength technologies across SMF, MMF, multicore fiber, and novel fiber platforms.

While recent VCSEL devices have achieved bandwidths of up to 50 GHz, the next generation of 200G and 400G solutions requires:

• Advanced methods to reduce RC parasitics
• Scalable packaging concepts with efficient heat dissipation
• Bandwidth-unlimited, current-insensitive modulation schemes

Expansion of VI Systems’ IP portfolio

To address these challenges, VI Systems has acquired several patents, including:

• US8313962 – Method for attaching optical components onto silicon-based integrated circuits
• US7593436 – Electrooptically Bragg–reflector stopband–tunable optoelectronic device for high–speed data transfer
• US7772615 – Anti-Stark electrooptic medium and electrooptically modulated optoelectronic device based thereupon

With this acquisition, VI Systems’ intellectual property portfolio now comprises 32 granted patents, with two additional patents currently under review by the USPTO.

These newly acquired patents reinforce our commitment to pioneering ultrafast optical interconnects for AI clusters and high-speed Ethernet networks. They strengthen our ability to deliver innovative solutions for the rapidly growing demand in data communication.
