An optical fiber cable includes a rollable ribbon, reinforcing yarns, and a jacket. The Rollable ribbon has a plurality of optical fibers. Each optical fiber has a fiber strain greater than 0.6 percent under standard installation tensile load. The jacket encloses the rollable ribbon, the optical fibers and reinforcing yarns at a packing density greater than about 1.25 fibers per square millimeter. The combined effect of optical fibers having a fiber strain greater than 0.6 percent under standard installation tensile load and a small amount of reinforcing yarn provides the optical fiber cable with high proof strain, compact diameter, and high packing density.
