A high-density optical fiber cable interconnect includes a fiber ribbon or fiber ribbon cable having at least one fiber ribbon and first and second ends. The fiber ribbon is formed from small diameter optical fibers arranged in at least one row, with each fiber having a glass section and a non-glass coating section surrounding the glass section. The diameter of the non-glass coating section can be less than 205 microns. A matrix layer encapsulates the small diameter optical fibers to define the fiber ribbon. A first optical connector terminates the first end of the fiber ribbon or fiber ribbon cable and has a first fiber pitch correspond to a standard optical fiber connector. A second optical connector terminates the second end of the fiber ribbon or fiber ribbon cable and has a second fiber pitch less than that of a standard optical fiber connector.
