Title: It's official, ADSL works over wet string...
Post by: jelv on December 12, 2017, 10:55:12 PM

... but the water does need to be salty!

That was quite hilarious, but another interesting experiment done by someone at AAISP :P.

What's the attenuation? loss per km? I doubt it'll be  one sisal fits all service! ;D

Reason being that salt is an electrolyte. When dissolved in the water the chloride ions which have a negative charge provide the electrons to enable a current flow.

I am sure this report will be tabled at an OR meeting and we can then see what happens.

The next experiment: xDSL usage over one strand of rusty barbed-wire.  :)

Some might say that is what OR use at the moment....

Thats hilarious someone actually tried it.   

Anyone else notice the reading on the JDSU?  - Estimated line length 4.5km

 :lol:

That will be because the HST-3000c SIM being used dosen't have the parameters for salty wet string and so assumes it is a thin gauge copper or aluminium metallic pathway!  ;)

Yes, I gathered that when I saw the attenuation was reported as 56dB.  My own max speed checker works in a similar way to give an estimate of standard gauge copper.
 
It just amused me that the attenuation of a 2m length of (salty) string was more or less equivalent to 4.5km of copper. 
Perhaps I should update mine to include string  :lol: :lol:
