Nokia announced it’s third generation coherent in-house DSP family. AMopng support for higher modulations and baud rates supporting up to 2x600G transmission, it added probabilistic constellation shaping (PCS) which maximized channel capacity.
“With the arrival of the new PSE-3, Nokia is making a significant leap forward in the performance of high-end coherent DSPs. PCS enables network operators to extract maximum spectral efficiency out of their networks. This technology also enhances all distances and applications, which makes it ideal to address the requirements of not only cloud and colocation operators but also traditional incumbent and cable MSO providers.”
