Abstract:
1. A system for increasing the amount of information transferred in optic fiber cables by increasing the number of optic fiber cores per cable, by at least one of: increasing the number of fibers per cable, increasing the number of cores per fiber, and/or increasing the number of multi-core fibers used, wherein the system further comprises arranging the fibers to prevent stress in a configuration capable of containing and/or protecting from stress optic fibers and/or optic fiber cores, with an average density of at least 4 cores per square millimeter, comprising at least one optic fiber cable with at least one pipe and at least one of the following: a) At least one multi-fiber flat jacket that can move freely up and down within at least one cell that goes through the optic fiber cable, wherein the at least one cell has a width greater than its height, and the optic fiber cable can bend only in the direction of said height; b) At least one flat multi-core fiber which contains one or more cores height-wise and more cores width-wise than height-wise and can move freely up and down within at least one cell that goes through the optic fiber cable, wherein the at least one cell has a width greater than its height and the optic fiber cable can bend only in the direction of said height; c) A multi-layer structure with at least one fiber per cell, wherein at least one of the structure and the fibers within the structure can move up and down to compensate for the bends of the cable's pipe, and the multilayer structure is within a cell that goes through the optic fiber cable, wherein the cell has a width greater than its height, and the optic fiber cable can bend only in the direction of said height; d) Optic fibers wherein at least some of said fibers are holey fibers with a diameter of 38 micron or less, including the cladding and coating, which use wavelengths short enough to support a cladding of 10 micron or less in thickness; e) Optic fibers wherein at least some of said fibers are nano-fibers which transmit wavelength of visible light and/or shorter; f) A system for duplicating the laser sources that send data through the optic fibers, so that original laser beams are optically duplicated and each new beam is independently modulated on/off, so that the same laser sources can be used for multiple fibers and/or multiple cores, and multiple such duplicated beams of different wavelength are entered into the same fibers or cores; wherein at least some of said fibers are nano-fibers and the wavelengths used are visible light or shorter.
