An optical space transmission system according to the present invention is provided with a first transmission/reception device which radiates first reception light and second reception light whose polarization states are orthogonal to each other, and a second transmission/reception device which radiates third reception light alternately including a first reception light component whose polarization state is the same as the first reception light and a second reception light component whose polarization state is the same as the second reception light in a time-wise manner."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Transmission/reception device, optical space transmission system, and transmission/reception method","description":"In a digital coherent communication scheme utilizing polarization-multiplexed optical signals, it may be impossible to separate transmission light and reception light from each other with high precisi","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9705631","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.
