"You are correct sir!" to quote Ed MacMahon. 98% of the cable's design is to protect a very thin and delicate strand of glass in a very hostile environment. Sometimes it fails. The cable has many different kinds of rubber, steel braiding, vinyl and other types of materials all in various layers designed to cushion and strengthen the cable.
There's a sample cable diagram on the page with the article that started all this. There are layers of steel reinforcing strands wrapped around the glass fiber core. If the diagram is a good guide (it says "not to scale") there's actually more steel than glass fiber in the fiber optic cable as a whole.
