B.S.T.J. briefs: Adhesive sandwich optical fiber ribbons

In 1974 a proposal was made to put optical fibers together into easily handled units for optical communication purposes.1 This proposal suggested “the use of fiber ribbons consisting of linear arrays of fibers embedded in a thin, flexible supporting medium as components of a cable for fiber transmission systems.” This note is a brief description of fiber ribbons made by sandwiching fibers between two layers of polyester-backed adhesive (adhesive sandwich ribbons).
