Unsurprisingly, we had a request, which I am sure was tongue in cheek, to upgrade a customer line to wet string as it seems faster than his quite long ADSL line.
Don't say we don't have a sense of humour at A&A, and no, I did not write this myself :-
Thanks for your interest in our latest technology, ADSL over wet string (fibre broadband)!
Sadly ADSL over wet string is not a product we can commercially offer at this moment in time - partly because it's not a product Openreach sell (or list as selling) to their wholesalers, and partly because, well, it's something we did for giggles as I'm sure you know :)
Looking at the loop loss on your circuit, it's currently running at about 48dB. In our tests with wet string, we attained 56dB on a line length of just 2 meters, which is about the range where the DSL signals starts to fade out.
My very scientific estimate of loop loss using wet string gives about -∞dB loop loss on your estimated line length of 3197 meters, which suggests that providing a wet string service to you is impossible given the losses, you would just not get sync.
Our tests took several attempts to raise sync on a wet string circuit, these timed between 5 and 60 minutes depending on local weather conditions ie. whether the air conditioning was turned on in the office.
I must warn you additionally, that the upkeep of these wet string connections is very hard; in our tests, we had to continually re-wet the string approximately every 30 minutes to avoid a complete loss of sync, and this process was always disruptive to the signals.
Perhaps if there's an exchange within 2 meters of your demarcation point, and if it's ever commercially offered as a product by the wholesale providers we buy from, it might work, but at this stage, wet string is sadly not a viable product for all involved. I suspect it may be expensive too - as there will need to be an engineer trained in keeping the string damp should the British weather deviate from it's usual damp and rainy grimness present unless it's made a self-service option, but that sounds annoying to be honest.
