🔴 Red LOS Light or Unplugged WAN Diagnosis
A flashing red LOS LED on optical GPON ONUs indicates optical power has dropped below -30 dBm, or the single-mode fiber patch cord has microbends.
- Inspect the green SC-APC optical connector on your ONU. Ensure it is firmly seated without heavy bends.
- Power-cycle the ONT/ONU for 30 seconds. If LOS remains solid/blinking red, contact your ISP technician immediately.
- On DSL/Cable modems, verify the coax/WAN cable and check for localized provider outages.
