networks?<\/b><\/strong><\/p><p>It is a backup power solution designed to keep FTTH customer-side devices such as ONT, ONU, router, or gateway online during a power outage.<\/p><p><strong><b>Q2: <\/b><\/strong><strong><b>Why is ONT backup important in FTTH networks?<\/b><\/strong><\/p><p>Because if the ONT loses power, the subscriber loses broadband service even if the upstream fiber network is still operating.<\/p><p><strong><b>Q3: <\/b><\/strong><strong><b>Can one Mini UPS support both ONT and router?<\/b><\/strong><\/p><p>Yes, if the total load is within the output capability of the Mini UPS and the required runtime remains realistic.<\/p><p><strong><b>Q4: <\/b><\/strong><strong><b>What is the difference between ONT-only backup and ONT plus router backup?<\/b><\/strong><\/p><p>ONT-only backup usually needs lower output current and less battery energy. ONT plus router backup requires more current support and careful runtime calculation.<\/p><p><strong><b>Q5: <\/b><\/strong><strong><b>Is 12V 3A enough for FTTH backup?<\/b><\/strong><\/p><p>In many standard ONT-only applications, yes. For higher-power or dual-device backup, 12V 5A may be more suitable.<\/p><p><strong><b>Q6: <\/b><\/strong><strong><b>How do I estimate backup time?<\/b><\/strong><\/p><p>Backup time depends on battery energy, device load, and system efficiency.
