Nokia has been delivering coherent technology innovation to break through optical networking barriers since the first commercial deployment of a single-carrier 100G wavelength in 2010. We built on this success with the deployment of the Nokia PSE-2 super coherent digital signal processor (DSP), which achieved additional industry-first milestones.
Our new PSE-3 continues this innovation momentum by taking coherent digital signal processing to the Shannon limit for the ultimate in wavelength performance at any distance.
The first chipset to implement probabilistic constellation shaping (PCS), the PSE-3 dramatically increases capacity while lowering power and costs per bit. Probabilistic shaping enables carriers to optimize capacity and spectral efficiency on every route, and it reduces operational complexity by supporting simplified spectrum planning and automatic wavelength optimization.
These foundational PSE-3 and PSE-2 technologies power our broad optical networking portfolio. They place the right DSP performance in products to efficiently address the needs of all networking applications, including metro, long haul, data center interconnect, and subsea.
The PSE-3 super coherent DSP with PCS allows service providers and webscale companies to meet the surging traffic demands of video, cloud, and 5G by maximizing the capacity and performance of every link in the optical network.
The patented algorithms that implement PCS maximize capacity over any distance and on any fiber – from metro to subsea.
The Photonic Service Engine 3 is lighting the way to a new approach and taking optical networking to the limit of physics. Fulfill your network’s true potential with maximum capacity and radically simplified programmability.
The PSE-2 was the first coherent DSP with super coherent technology capable of powering flexible, multi-modulation 50G–250G wavelengths. With multiple modulation and baud rate options, products based on PSE-2 can flexibly adjust and adapt their capacities to each optical route.
Nokia Optical Networking technologies let you build agile and scalable networks that accelerate the delivery of mobile, video, business, wavelength, Ethernet, data center interconnect, and cloud services. With solutions powered by our highly programmable PSE Super Coherent Technology, you can economically scale your network to support 100G connectivity services.
