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. ?
