Abstract: A high fiber count, ferrule-terminated optical fiber cable assembly includes a high density two-dimensional array of optical fibers extending through a single aperture of a ferrule, with the optical fibers within the ferrule aperture each having a core, a cladding layer, and a hard coating layer (e.g., having an elastic modulus greater than 100 MPa). Hard coated optical fibers are arranged very close to (e.g., within two microns of, or in contact with) one another, with a substantially constant fiber pitch within the ferrule. A fusion splice region may be provided between ferrule terminated hard-coated optical fibers and conventional optical fibers lacking a hard coating. High optical fiber density and compact ferrule size permits a significant reduction in connector width, enabling a numerical reduction or elimination of staggered lengths of cable portions for coupling ultra-high density optical fiber cables.
