Provided is an improved optical glass fiber, ribbon unit having the capability of providing mid-span access to individual color-coated optical glass fibers contained therein by application of finger pressure from a human hand. The ribbon unit is made of a plurality of coated optical glass fibers each further coated with a cured color-composition; and a matrix material which binds the plurality of color-coated optical glass fibers together, wherein a bonding force between the cured color-composition and the coated optical glass fibers is greater than a bonding force between said cured color-composition and said matrix material, and wherein the matrix material has been selected or formulated to provide a modulus and Tg sufficiently high such that when opposing pressure is applied to the ribbon unit using the fingers of a human hand, the matrix material buckles and separates from said color-coated optical glass optical fibers instead of compressing and absorbing the opposing pressure. Also provided are a method of making the ribbon unit, and a method of achieving mid-span access to individual color-coated optical glass fibers contained within the ribbon unit. |
