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 15):
An optical transmission link comprising\n (a) a first and a second node connected by an optical path, (b) the nodes being configured to establish a bidirectional optical data communication link comprising at least one optical communication channel at a dedicated data channel wavelength and a bidirectional optical supervisory channel at a dedicated supervisory channel wavelength differing from the data channel wavelengths, (c) each of the nodes comprising an add/drop filter means provided right at the first and second end of the optical path or sufficiently close thereto, respectively, the add/drop filter means being configured to integrate an optical supervisory channel signal into an optical WDM signal to be transmitted to the respective other node and to extract an optical supervisory channel signal from an optical WDM signal received from the respective other node, (d) wherein the nodes further comprise a device for determining the latency or length of the optical path according to  claim 12 .
