Several optics from the University of Bath have created a new type of optical fiber that will significantly improve light transmission. The light moves through the silicon marrow doped in the normal optical fibers, so there are limitations for the transport of light: for example, the diameter of the fiber must be very small, otherwise the light begins to move transversally, it is reflected in the walls and the luminous signals arrive outdated at the end. On the other hand, doped silicon does not serve to transport luminous signals of different wavelength.
In the new optical fibers the light moves in fine holes located in the marrow, thus avoiding the doping of silicon. This increases the transmission capacity of the fiber and can transport signals of different wavelength, so each length can be used to transmit a type of information. In addition, these fibers serve to transport more powerful light signals, so that along its path less amplifiers will be needed for the signal to reach its destination.
