Nokia Subsea

Powerful optical transmission systems that deliver performance and new revenue

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.

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. ?
