It connects to your router via a LAN / ethernet cable and translates light signals from the fibre optic line from your TP into electronic signals that your router can read. Thus, without a good noise reduction design to eliminate such external noise sources, a perfect prototype ADSL modem will not work in a real world noise environment. These will not clarify the signal, but rather filter out the unwanted frequency. Noise in optical communication typicaly refers to the deviation from an ideal signal, and is usually assocoated with random processes. That noise is coming from the onboard modem speaker, and is caused by your computer connecting to another computer. Call your dr and explain the noise to him.
