1. A method for selecting multimode optical fiber for use in a communications network, said method comprising:

  • measuring a pulse delay for pulses traveling through different radii of a number of multimode optical fibers;

    subtracting the pulse delay at a first radius of each multimode optical fiber from the pulse delay at a second, larger radius of each multimode fiber; and

    choosing for use in the communications network those optical fibers in which the result of subtracting the pulse delay at the first radius from the pulse delay at the second radius is a negative number.
