Claim 0:
1. An optical-fiber ribbon, comprising:
(i) a plurality n of respectively adjacent optical fibers extending in a longitudinal direction and arranged in parallel to form an optical-fiber assembly having a width w extending crosswise to a longitudinal length of the optical-fiber assembly, wherein the n optical fibers are arranged in a plurality U of respectively adjacent optical-fiber units; and
(ii) bonding material deposited on a major surface of the optical-fiber assembly, the bonding material adhesively bonding adjacent optical-fiber units and the corresponding adjacent optical fibers in the optical-fiber assembly, wherein:
adjacent optical fibers within each optical-fiber unit are respectively contiguous to one another;
each adjacent pair of optical-fiber units is separated by an adhesive-free spacing for a respective portion of the optical-fiber assembly's longitudinal length, the respective adhesive-free spacings between adjacent optical-fiber units having a mean width Savg,
the n optical fibers have a mean diameter davg; and
the respective adhesive-free spacings have a mean width Savg that is at least 50 percent of the mean diameter davg of the n optical fibers.
