However, commonly used optical fiber used in telecommunication is made out of glass. A fiber optic has 3 main structural sections core, cladding and jacket. Jacket is a protective cover over core and cladding and has no role in transferring light from one end to other. The light is solely transmitted by core and cladding glass structure. Hope it helps.

Anyone who has terminated one can attest to that. They are solid glass with a reflective cladding. Let's not let any other rumors start here. “Fiber optics are also hollow, but not every hollow thing is a fiber optic”

No, i think the polar bear fur, being hollow, keeps a layer of insulated air between the bear and its frigid environment. seems like a more believable answer then black showing through white, or fiberoptic fur(fiberoptic wires are a synthetic, aren't they?)if it were that easy, we could just shear the hear and spin it for the wires, like sheep. i have to agree, the black skin isnt even visible so it cant be used to catch sunlight.
