The determining includes converting time differences between the counters into distance, based on propagation speed of a signal over optical fiber forming the link. The location is determined in-service based on a single occurrence of the event without external equipment."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"In-service optical fault isolation systems and methods","description":"Systems and methods for in-service optical fault isolation on a link between a first node and a second node include transmitting counters between each of the first node and the second node; determinin","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9806801","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.
