A cable assembly (2) includes a cable member (4) and an outer jacket member (6) disposed about the fiber optic cable member in slidable relation. In a preferred embodiment, the outer jacket member is a woven article, made from low friction, synthetic fibers such as polyester, nylon, Teflon, PEEK, or polyvinylidene fluoride. The outer jacket member (6) serves as a sleeve that extends at least the same length as the cable member (4). In use, the outer jacket (6) carrying the cable member (4) may be attached at one end to a pul l cord or tape (8) that extends through the length of a conduit. A pulling for ce is exerted on the pull cord (8) at a remote end of the conduit, causing the outer jacket member and cable member to be drawn through the conduit. The outer jacket bears most of the force of the pulling action, and the only for ce exerted directly on the fragile cable member is that of friction between the jacket and the cable. This arrangement substantially increases the amount of force and speed with which the cable assembly (2) may be drawn through the conduit, while reducing the amount of friction and eliminating the need for lubricants during the process.
