In order to construct optical access networks economically for fiber to the home (FTTH), it is important to reduce the cost of optical fiber cable installation. Optical fiber and cable costs have been reduced over the past ten years, however there have been few reports describing installation cost reduction. In this paper, we describe the design of high-density optical fiber cable that reduces the required installation time. To achieve this we have reduced the optical fiber cable weight and the friction coefficient of the cable sheath. We reduced the cable weight by using polyethylene foam and a non-metallic tensile strength member made of a new material, PBO. These two approaches reduce the cable weight by a total of about 30%. We also added a lubricant to the polyethylene sheath of this cable and this reduced the pulling force required for the additional cable by 30%-50%.
