Do signals really travel faster in fiber optical?

You might be surprised to know that signals in UTP (unshielded twisted pair) cables like Cat 5e travel at about the same speed (2/3 C) as in fiber optical. Coax, meanwhile, has a faster NVP (nominal velocity of propagation), about 0.9C, due to its design. Fiber’s “speed” is not referring to the speed of the signal in the fiber, but the bandwidth potential of the fiber.
