-⚠️ **The ONT's serial logic is 3V3**: Make sure the logic of your TTL converter is 3V3 too otherwise you might damage the ONT, in my case i wasn't sure the CH341A had a 3V3 logic for the TTL part so i've set up a voltage divider made of 2 resistors between the TX pin and ground as shown in the image below
