Abstract: An optical connecting system for connecting a first and a second optical device includes a first and a second multi-fiber device connector included in the first and second optical device and a multi-fiber optical connection cable including a plurality of optical fibers and having a first and a second multi-fiber cable connector at a first and second end thereof and being adapted to be connected to the first and second multi-fiber device connector. The optical devices are configured to transmit to and/or receive from the other optical device wanted optical data signals via optical fibers of the multi-optical fiber connection cable.

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.
