Building a Better Backbone
May 16, 2001 | Source: Technology Review
Surging Internet growth is straining the capacity of the Internet backbone. New developments to increase bandwidth include Raman amplification (allows a signal to be amplified without introducing noise), polarized light, and “photonic-band-gap crystals” to eliminate interference between wavelengths.
Current research could enable holographic 3-D videoconferences, long-distance surgery, and instantaneous access to books stored at any library in the world.
