A network management system may configure optical transponders to apply probabilistic shaping to a QAM modulation format in accordance with the selected shaping parameter pair. A shaping parameter pair specifying a high shaping strength level and a low error correction strength level may be selected when the measure of fiber nonlinearity is high. A shaping parameter pair specifying a low shaping strength level and a high error correction strength level may be selected when the measure of fiber nonlinearity is low."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Probabilistic constellation shaping for optical networks with diverse transmission media","description":"Systems and methods for constellation shaping of QAM modulation formats in an optical transport network may include selecting a target information rate for an optical transmission path, determining a ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10530490","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
