A fiber optic cable assembly includes first and second fiber optic ribbons and a splice protector. The ribbons are spliced together such that the corresponding spliced fibers at the splice have a common lengthwise axis, widthwise axis orthogonal to the lengthwise axis, and thickness axis orthogonal to the lengthwise and widthwise axes. The splice protector supports the ribbons that are spliced to one another at the splice. The splice protector may include or even consist essentially of an adhesive that provides a flexible support for the splice. The splice protector may be at least half as flexible when cured over the splice as the first and second ribbons in bending about the widthwise axis.
