Color-coded optical fiber ribbon and die for making the same

An optical fiber ribbon comprising:

• a plurality of substantially parallel, adjacent, longitudinally extending optical fibers disposed, at least at a given cross section of said optical ribbon, in substantially the same plane;
• at least one coating on each of said plurality of optical fibers;
• a plurality of sub-units that include a subset of said plurality of optical fibers, each sub-unit covered by a sub unit resin matrix material;
• and
• a common resin matrix material surrounding said plurality of sub-unit resin matrix materials and forming an outer surface of said optical fiber ribbon,
• wherein said sub-resin matrix material and said common resin matrix material are of at least two colors to provide a color-coding identification scheme for said optical fiber ribbon.
