Abstract
The disclosed power cable enables optical fibers to be installed after the power cable has been installed, thereby forming a hybrid cable. Segments of the power cable are manufactured with fiber installation tubes containing pulling members. When the power cable segments are coupled together, the fiber installation tubes and pulling members also are coupled together to form a fiber installation conduit and an extended pulling member. A fiber pull arrangement can be coupled to the extended pulling member and drawn through the fiber installation conduit within the power cable at any time subsequent to installation of the power cable.
