Set to become the ubiquitous network interface across IP, optical, and data center networks, 400G marks the first common data rate since the introduction of 100G approximately 10 years ago. As the foundational technology for high-bandwidth transport, the critical task for electro-optics in the coming years will be to deliver 400G services at the lowest cost across a wide range of network applications, each with distinct size, power, and performance requirements.
Nokia’s WaveFabric Elements portfolio combines digital signal processing (DSP) and optical technologies focused on emerging end-to-end 400G applications, enabling Nokia to optimize the entire electro-optical engine powering current networks and future transformational upgrades. This high degree of vertical integration ensures that Nokia’s optical solutions meet the unique technical and economic requirements of data center, metro, long-haul, and submarine networks.
Nokia’s fifth-generation coherent DSP family, comprising the high-performance (super-coherent) Nokia PSE-V and the low-power (compact) PSE-Vc, continues Nokia’s history of developing multiple DSPs optimized for different optical network applications, form factors, and platforms. The new DSPs are complemented by the CSTAR portfolio of coherent optical engines brought to Nokia through its recent acquisition of Elenion Technologies, a pioneer in silicon photonics. A new family of pluggable transceiver modules enables Nokia to address its critical and expanding role in the data center, IP and optical networks, as well as in emerging markets and applications highly dependent on low-cost optical connectivity, such as access and mobile networks.
