The signal splitting element is capable of splitting signals independent of signal frequency and may be a directional coupler, two-way signal splitter or hybrid coupler comprising at least two different types of coupler element."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Optical network device","description":"There is provided an optical network device (30) comprising separate downstream and upstream signal paths (33, 34) disposed between a wavelength division multiplexing unit (16) and a signal splitting ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11949454","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.
