Abstract
A optical fiber having core and cladding regions, a primary coating, and a secondary coating may be defined in part by a curve relating the microbend sensitivity to a ratio of the elastic modulus of the secondary coating to the elastic modulus of the primary coating (as plotted on respective y and x axes). The curve has a substantially peaked shape defined by a positive-slope region and a negative-slope region. The ratio of the elastic modulus of the secondary coating to the elastic modulus of the primary coating is within the positive-slope region.
