Power cable with ability to provide optical fiber upgrade

摘要

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.

主权项

1. A hybrid cable comprising:
(a) a plurality of sheaths having axial ends coupled together by sheath connecting members to form an extended cable; (b) a plurality of insulated conductor having axial ends coupled together by conductor splice arrangements to form extended insulated conductors within the extended cable; (c) a plurality of fiber installation tubes having axial ends coupled together by tube connecting members to form a fiber installation conduit within the extended cable; and (d) a fiber pull arrangement disposed within the fiber installation conduit, the fiber pull arrangement including a plurality of optical fibers coupled to a strength member.
