Abstract
A new, unique, small diameter, more robust fiber optic breakout cable comprising a central member about which several sub-unit ribbon cables are helically stranded using a planetary stranding method. Each sub-unit ribbon cable contains a plurality of optical fibers in side-by-side relation, surrounded by strength members and encased by a protective jacket. A protective outer cable jacket encases all of the jacket protected sub-unit ribbon cables stranded about the central member.
Claims9
An optical fiber cable comprising:
- (a) a central member;
- (b) a plurality of oval shaped ribbon sub-units each having a single linear arrangement of a plurality of optical fibers in adjacent alignment surrounded by strength members and a protective ribbon jacket encasing said fibers and said surrounding strength members, said ribbon sub-units helically stranded about said central member in a planetary configuration such that ends of said linear arrangements of optical fibers oppose each other;
- and
- (c) an outer protective jacket encasing said central member and said ribbon sub-units.

An optical fiber cable comprising:
- (a) a central member;
- (b) a plurality of layers of two or more oval shaped ribbon sub-units each having a single linear arrangement of a plurality of optical fibers in adjacent alignment surrounded by strength members and a protective ribbon jacket encasing said fibers and said surrounding strength members, said ribbon sub-units helically stranded and layered about said central member in a planetary configuration such that ends of said linear arrangements of optical fibers oppose each other in each layer of ribbon sub-units;
- and
- (c) an outer protective jacket encasing said central member and said layers of ribbon sub-units.
