optical interconnect technical

"adoption of optical interconnect technologies designed for high-density computing environments."

Optical interconnect is a way of linking electronic components using pulses of light instead of traditional electrical wires, like swapping copper cables for fiber-optic highways inside and between devices. It matters to investors because light-based connections can carry much more data, use less power and generate less heat than electrical links, which can lower operating costs and enable faster, more scalable products for data centers, telecom and high-performance computing markets.

hyperscalers technical

"support customers across the data center ecosystem—including hyperscalers, optical network equipment..."

Hyperscalers are large technology companies that operate massive computing networks and data centers to provide cloud services, data storage, and online infrastructure at an enormous scale. They are essential to the digital economy because they enable businesses and organizations to handle vast amounts of data and run complex applications efficiently. For investors, hyperscalers represent powerful engines of growth and innovation in the technology sector.
