Today, data centers use a separate approach for optics and electronics, in which optical modules are connected to switches and routers through high-speed electrical interfaces. As data demands grow, these systems face limitations such as bandwidth constraints, latency issues, and space limitations. MALTA, N., May 04, 2026 (GLOBE NEWSWIRE) -- GlobalFoundries (Nasdaq: GFS) (GF) today announced the introduction of its SCALE™ optical module solution for co-packaged optics (CPO). GF's SCALE solution, or Silicon photonics Co-packaged Advanced Light Engine solution, is the industry's first Optical. The rapid development of AI, IoT, 5G and high-performance computing applications has led to exponential growth in data traffic within data centers. Nearly three-quarters of this data traffic remains within the confines of data centers. Traditional pluggable optics cannot keep up with this surge. As datacenters strive to meet escalating demands for efficiency and bandwidth, particularly with the integration of AI and ML technologies, optics is poised to play a crucial role in shaping the future of interconnect architecture and performance. The increasing investment in innovative. Co-packaged optics (CPO) technology, a key enabler for next-generation data center architectures, promises unprecedented bandwidth density and power efficiency by tightly integrating optical engines with switch silicon.
