Upon receipt of the Discovery Gate message, each ONU consecutively transmits Register Request messages. The uplink optical switch SW(UP) sequentially switch signals from ONU#1 through ONU#128 in the slots arranged in a discrete manner, and outputs the signals to the OLT, Some of the Register Requests transmitted from the respective ONUs pass through the SW(UP), and reach the OLT. Based on the received Register Requests, the OLT determines the timing of transmission for the ONUS, and notifies the ONUS of the timing of transmission through a Gate message."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Line control method in optical network and optical network itself","description":"In an access network using optical switches, communications between an OLT and ONUs are established without a photoelectric conversion performed at an optical switching unit.The OLT controls the downl","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8488964","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.
