Light waves

The operation in front of fibre optic systems shall become known, presupposed as fundamental.

If this should not be the case, the comprehensive literature is referred open.

To this the very good publications read in Wikipedia

Production of the light signals
Glass fibre or other fibres
Receiver of the visual signals
concrete example (Transatlantiikkabel 14 )

This basic knowledge is, also the basis the understand the modern information extraction at these workhorses.

The analogous "interesting places" of the information extraction for the starting-points of modern type of the information extraction, so also here already were for line systems in the wired one.

These analogies, simplify understanding the working principles of modern information extraction by "third parties"

At these danger descriptions we must on technically - physically practicably restrict methods for us. The appropriately available potential of the "third parties" is greater , potential mur can, however, technically - physical be speculated about this.

Therefore we only confine ourselves to the practicable Verfahren, it however well knowingly works still better.

Now to the starting-points of modern information extraction.



The end or entrance of the communication of the cybernetic system (hardware - unity) is (defined interface)

1, starting-point. This followingly comes the information signal in a signal wandelt. adapted to the communication channel light signals on the transducer unity, this one, (. )

2nd starting-point,
the communication channel is between units obliged to the both or several. In this case it shall be light wave conductors who send photons to others of an end end. This line consists made of which material at here is insignificant.

  3rd starting-point
with increasing length of the light wave conductor the photon signals also become thanks to the natural processes, as far as muffled, the one reinforcements of the signals are required.

4th starting-point .
They reach the receiver at the end of the line after a different residence time of these photons in theline. System photon current coming this in from this causes an electrical signal a technical. This signal can more and more or directly into the and reception interface of the hardware sends - - will submit unity. The information as an electrical signal string is available here.


The use of the concept "signal string" is not carried out of approximate. This bit stream can do information of all sorts of kind contained of word, document, picture to video or other sources. /font>
