Solitons for the management of dispersion Explanation: A soliton is a theoretical individual pure wave, hence the name soliton. The closest approximation to it in nature is the progressive free running wave on a canal. The theory of the soliton is well understood. Waves in nature are normally associated with dispersion, that is their bandwidth increases as they travel. Here, I believe, the engineers a using the soliton theory to fine tune the fiber optic channels to individual "very narrow" bandwidths (solitons) so that the overall bandwidth of the fiber optic channel can be increased.

..use the technology of solitons, by controlling dispersion Explanation: In fiber optics we can have dispersion of photons. Your text talks about a new technology, which uses solitons. The use of solitons allows the transmission of a great number of channels in an optical fiber. The advantage of solitons is that they are very robust against perturbations in the fiber. They go through quite easily, without changing shape. I believe that "A gestion de dispersion" means that they (the company) are controlling dispersion. Dispersion can affect the transmission of solitons. You cannot easily eliminate dispersion completely, so the way to control it is to introduce nonlinearities, so that the latter balance the dispersion. The technique used is WDM (wavelength division multiplexing), which means that a different wavelength is assigned to each channel. So, more channels= more wavelengths= many different velocities and high rates. myself |

Please see below: Explanation: "...utilise the technology of solutions for the management of dissemination." "This technology allows the transmition of a high number of channels WDM through fiber optic cables..." Regards. Luis Luis |
