Foundational electro-optics silicon innovation to support the efficient delivery of 100G services. As routers utilize more 100GE interfaces and enterprises demand more 100G connectivity services, a new level of scale and economics is required from optical transport networks. Getting there is critical given the unrelenting rise in demand for high-speed, high-quality, always-on connectivity in an environment of increasing competition. Building on the world’s first programmable, coherent digital signal processor (DSP) — the Photonic Service Engine 2 (PSE-2) — Nokia optical network solutions are ready to economically scale networks to support the successful delivery of 100G connectivity services.
