"Minimizing impacts of noise for "Always On" services over VDSL2 Networks" by Manouchehr Rafie, Ikanos Communications.
Morceaux choisis :
"Rate/reach performance for multimedia services can be severely impacted by noise on VDSL2 lines that is a result of crosstalk coupling from electrical signals on adjacent pairs of copper wires or other impairments. Loop noise characteristics can change significantly as a result of on/off switching of DSL lines."
Ou encore :
* Common causes of performance degradation on DSL lines such as crosstalk, non-stationary radio interference disturbers, impulse noise and temperature changes;
* Techniques to minimize the impacts of noise to ensure that enhanced services are "always on"
On en revient toujours à la même source "Le cuivre est une éponge !"
