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.

Claim (Index 12):
A device for determining the latency or length of an optical path of a fiber-optic transmission link, comprising:\n (a) a first optical transceiver at a first end of the optical path and a second optical transceiver at a second end of the optical path, the first and second optical transceivers being configured to establish a bidirectional optical supervisory channel between the first and second end of the optical path; and (b) a control device provided at the first and second end of the optical path, wherein the control device is configured:\n (i) to start a measurement cycle at a first point in time, \n (ii) to control the first and second transceivers in such a way that measurement bits or bit patterns are created and transmitted forth and back between the first and second ends within the optical supervisory channel between the first and second ends, beginning at the first end at the first point in time, for a predetermined number of round-trips; \n (iii) to stop the measurement cycle at a second point in time after having received a last measurement bit or bit pattern at the first end; \n (iv) to determine, at the first end, a total round-trip delay of the optical path by evaluating a time information available at the first end, wherein the time information at least comprises the first and second points in time, and taking into account the predetermined number of round-trips; and \n (v) to calculate the latency of the optical path by using the total round trip delay and/or to calculate the length of the optical path by using the round-trip delay and the group velocity characterizing signal transmission over the optical path.
