Fiber Optic Cable Response Delay
In a fiber optical communication systems it is essentially the length of optical fiber divided by the speed of light in fiber core, supplemented with delay induced by optical and electro optical elements plus any extra processing time required by system, also called. Fiber latency is the time it takes for data to travel from the transmitter into the optical link and reach the receiver. Subsea fiber optic links carry most intercontinental internet traffic, so even small changes in route length or signal speed can matter. 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.
