On the Web, you can often find jokes about the fact that the Internet can work at least by the ropes. However, all this seemed complete fiction and nonsense, until the engineers of one of the providers in Britain did the test. The employees of Andrews & Arnold jokingly decided to find out whether the rope saturated with saltwater is suitable for the role of a cable Internet line.
In their office was all the necessary equipment to make the necessary measurements. It turned out that on a rope about two meters long it is possible to organize broadband access at a speed of about 3.5 Mbit / s. Not much, but enough to take advantage of most of the basic features of the World Wide Web. Thus, not only the “share of the joke” turned out to be a joke but also a fair amount of truth.
The British tested the operation of ADSL technology (asymmetric digital subscriber line), which once again proved its high flexibility. Its difference is that it is allowed to work on lines whose condition is far from ideal. But how could it turn out that the rope turned out to be suitable for creating an Internet channel because its characteristics differ significantly from the characteristics of copper cables? Professor Jim Al-Khalili, who works at the University of Surrey, was an expert in this dispute and stated that this fact has a completely scientific explanation.
It turns out that ADSL does not require the same low resistance as copper. Data transfer is not so dependent on this parameter. Information is transmitted at high frequencies, which are well distributed in any environment, including in a wet rope.
