Abstract

A cable includes an inner core. In one embodiment, the inner core includes at least one optical fiber, plural flaccid strength members, such as aramid yarns, and at least one rigid strength member, such as one or more GRP rods. A jacket surrounds the inner core. The jacket has an undulating thickness which results in plural projections formed on an outer surface of the jacket, extending along the length of the cable. In a first embodiment, the at least one optical fiber is centrally located within the inner core and surrounded by a buffer tube, which is surrounded by plural GRP rods. In other embodiments, the at least one optical fiber is centrally located within the inner core and located within a channel formed in a single GRP rod or located within a buffer tube, which is placed in the channel formed in the single GRP rod.
