What is the RX side of optical power you are receiving?
You can check this in your ONU.
If you are too lazy to check by unplugging ONU and shit, dont worry, just create an interface for static IP in openwrt for ONU and choose any IP in the subnet of your ONU's IP.
Then you can access ONU without doing any hardware changes.
