The fiber latency calculator helps determine the time it takes for data to travel through a fiber optic cable between two points. In free space, light travels at 299,792,458 meters per second. When transmitting over. Latency in fiber optics refers to the delay time, or 'time delay', it takes for a light signal to travel from the transmitter at one end to the receiver at the other, factoring in the calculation of fiber latency which includes the speed of light in the fiber, the index of refraction, and the. nd has not been measured with a high accuracy. In this paper, we report on those measurements, using a Correlation-OTDR (C-OTDR), yielding a high accuracy of the absolute fibe at ncy on the order of entral office in Meiningen, i Central Germany.
