Fibre optic cables' data capacity may soon be reached Technology may stretch the capacity of the fibre optic cables used to carry data sooner than has long been thought, according to a report in Science. At this year's Optical Fiber Communication Conference (OFC 2010), several groups reported results within a factor of 2 of the ultimate capacity limits of existing optical fiber technology. Without radical innovation in our physical network infrastructure—that is, improvements in the key physical properties of transmission fibers and the optical amplifiers that we rely on to transmit data over long distances—we face what has been widely referred to as a "capacity crunch" that could severely constrain future Internet growth, as well as having social and political ramifications.

It won't probably happen in near future, but if HD Video, do become norm of the day (as mentioned) + the price at which you can your internet connection (with greater bandwidth) will determine when this happens.
