Abstract
A high density fiber optic cable including a cylindrical core member having a number of helical grooves extending along its length. Up to a hundred or more optical fibers are placed into each helical groove. The core member and fibers are covered by an outer member which retains the fibers and acts as an environmental seal. A strength member can be placed within an internal void in the core or the outer member can act as the strength member. Where the outer member is the strength member, additional cables may be placed within the internal void.
