The specific Miller coding technique allows for a secondary data stream, operating at half the rate of the NRZ data) to supplement the primary 50 Gb/s NRZ transmission, since both signals are recovered using the same clocking circuitry at the ONU."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Flexible rate passive optical network incorporating use of delay modulation","description":"Apparatus and method are disclosed that utilize a particular delay modulation technique (i.e., Miller coding) to encode 25 Gb/s data for inclusion with the 50 Gb/s NRZ data in a downstream broadcast t","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11973537","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.
