Comment: Re:Not good for long haul use (Score 1) 104
This band is not useful for long haul carriage due to atmospheric water vapor absorption. According to this chart, absorption between 200 and 280 GHz varies between 3 and 40 dB/km. That means at the low end only 50% of your signal is absorbed every km. At the high end, only 1/10,000th of your signal remains after each km.
this post speaks to similar issues including refraction.
That has not and will NEVER stop $TELCO from selling services across this with "UP TO" marketingspeak which means "we fuck you royally for a service which is online but effectively unuseable".
