...Even more promising is the possibility of replacing conventional fiber optics used in communications with omniguides. The absorption of light by conventional glass fibers means that the signal must be boosted every 20 kilometers or so. This requires amplifiers, which only work in a narrow band of frequencies. Omniguides would carry light with far less loss of energy, meaning they could stretch for thousands of miles without amplifiers. Engineers would not be limited to a small band of wavelengths by the abilities of amplifiers. "You could have a thousand times the bandwidth. That's a very big deal," Dr. Fan said.
