Abstract

A method for installing a fiber optic cable in a building having a gas riser includes the steps of routing a first translating member from a riser entry location, through the riser, and out a riser exit location. A fiber optic cable near the riser exit location is engaged by the first translating member, and is retracted into the riser past a branch in the riser, so the fiber optic cable hangs down past the branch. A second translating member is routed from a branch entry location, through the branch, and into the riser. The fiber optic cable is engaged by the second translating member, and the first translating member is disengaged from the fiber optic cable. The second translating member, along with the fiber optic cable, is retracted through the branch and out the branch entry location. The fiber optic cable may then be connected to an end-user system.
