Photonic Service Engine (PSE) Coherent DSPs

Nokia has been delivering coherent technology innovation since the first commercial deployment of a single-carrier 100G wavelength in 2010. The Nokia PSE and PSE-2 super coherent digital signal processors (DSP), achieved several additional industry milestones as coherent technology became a foundational element of optical transport.

In 2018, Nokia implemented probabilistic constellation shaping (PCS) in the Photonic Service Engine 3 DSP. This revolutionary technology enhances performance to near theoretical limits, while at the same time provides ultimate flexibility in balancing rate versus reach. As the industry leader in the research and development of coherent high-speed optics, Nokia took the performance of light to the limit – the Shannon Limit.

With the introduction of its 5th generation coherent DSP family, Nokia is looking beyond the limit – to optimized coherent technologies with the right features, in the right form-factor, for the unique applications demanded by each and every part of your network.

PSE-V: Go beyond the limit

The Nokia PSE-V is the industry’s most advanced family of coherent digital signal processors (DSP), powering the next generation of Nokia WaveFabric high-performance, high-capacity transponders, packet-optical interfaces, and data center interconnect (DCI) platforms.

The PSE-V Super Coherent DSP supports higher wavelength capacities over longer distances – including support for 400G over any distance - while further reducing network costs and power consumption per bit.

The PSE-V Compact enables digital coherent optical modules, bringing the flexibility of pluggable modules to 400G coherent applications.

Together, they optimize power, performance, and cost across multiple form-factors addressing applications from metro to subsea.

PSE-3: Taking light to the limit

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.
