Nokia Subsea

Deliver performance and new revenue with powerful optical transmission systems

Taking light to the limit

Nokia subsea solutions utilize the industry’s strongest optical transmission technology, supporting record setting non-regenerated span lengths, maximum spectral efficiency and optimized equipment costs. Integrating terrestrial and subsea networks through a common platform and components provides seamless data center connectivity. 

At the heart of Nokia’s subsea solution is the Photonic Service Engine (PSE): a digital processor for super-coherent optical transmission that optimizes capacity for each unique optical span, utilizing Probabilistic Constellation Shaping (PCS), advanced SD-FEC coding, Nyquist filtering and infinitely variable capacity. PCS is the only optical processing algorithm proven to approach the Shannon limit in a real-world optical fiber. The result is a capacity gain of between 25 and 68% and a 60% reduction in power required per transmitted bit. 

Further, Nokia’s optical solutions include advanced wavelength routing capabilities, such as colorless, directionless, contentionless flex grid reconfigurable optical add-drop (CDC-F ROADM) to further simplify equipment, reduce physical footprint and cost while opening new deployment opportunities.  

A critical component to Nokia’s 1830 PSS and 1830 PSI solutions, the PSE is but the latest innovation in a long history of record-setting performance.
