  • Method and device for determining the latency or length of an optical path, especially an optical fiber, of a fiber-optic transmission link
    Patent number: 10498439
    Abstract: A method for determining the latency or length of an optical path of a fiber-optic transmission link includes: starting a measurement cycle at a first point in time; stopping the measurement cycle at a second point in time after having received a last measurement bit or bit pattern at the first end; determining, at the first end, the total round-trip delay of the optical path by evaluating a time information available at the first end; and calculating the length of the optical path by using the total round-trip delay and the group velocity characterizing the signal propagation along the optical path.
