at regular length intervals, identifying band markings attached to and circumscribing at least one transparent or translucent buffer tube of said plurality of transparent or translucent buffer tubes;
a plurality of color-coded buffer tubes;
non-color-coded filling material disposed within said color-coded buffer tubes; and
gelatinous color-coded filling material disposed within said transparent or translucent buffer tubes, wherein each of the buffer tubes is uniquely identifiable based on a three-dimensional code defined by identifying bank markings attached to the buffer tubes, color of the buffer tubes, and color of the filling material,
wherein at least two buffer tube have common identifying band markings,
wherein at least two buffer tube have a common color code, and
wherein at least two buffer tubes are filled with color-coded filling materials that have a common color.
5. A system for identifying optical fibers, comprising:

color-coded optical fibers occupying a portion of the internal volume; and
color-coded gelatinous filling material disposed within each of said buffer tubes, wherein each buffer tube contains a different color of filling material, and wherein the color-coded fibers and the color-coded gelatinous filling material occupy essentially all of the internal volume, and wherein the gelatinous filling material comprises one of pythalocyanime, azo dye, chromium oxide, lake pigment, guinolone, and lithopone.
6. A system for identifying optical fibers, comprising:
a plurality of transparent or translucent buffer tubes providing an internal volume;
color-coded optical fibers occupying a portion of the internal volume; and
color-coded gelatinous filling material disposed within each of said buffer tubes, wherein each buffer tube contains a different color of filling material, and wherein the color-coded fibers and the color-coded gelatinous filling material occupy essentially all of the internal volume,
wherein the gelatinous filling material comprises a pearlescent colorant.
7. A method for identifying or managing optical fibers in a cable, comprising:
color-coding optical fibers;
color-coding gelatinous filling material;
color-coding buffer tubes;
including the optical fibers and the filling material within the buffer tubes;
establishing a three-dimensional code, for uniquely identifying each respective optical fiber of the optical fibers, each respective optical fiber defined by a color of the optical fiber, a color of the buffer tube in which the optical fiber is disposed, and a color of the filling material within the buffer tube in which the optical fiber is disposed,
wherein at least two buffer tubes have a common color,
wherein at least two buffer are filled with filling materials having a common color, and
wherein at least two optical fibers have a common color.
