There are loss and gain in optica fibers due to dispertion and nonlinearity, respectively.

By changing the nonlinerity we can change index (n=n0+n2I) of fiber. Soppuse we decrease fiber index and we know v_ph= c/n , then we can incarese phase velocity.

In some cases which n is smaller than 1 . V-ph bacome greater than speed of light in that medium.

I hope it would help you
