System for continuous evaluation of optical path asymmetry
Original language description
Precise time and stable radio frequency dissemination is becoming standard application in optical networks. The White Rabbit system is commonly used for this purpose to support applications that require precise time and a stable frequency signal. Optical fibers are preferred for distributing the precise time and frequency signal in this system. To achieve best results, i.e. determine absolute offsets, it is necessary to know the asymmetry of the optical transmission path in which the system is deployed. We developed a device based on a MEMS optical switch that measures the delay of the optical path in both the forward and reverse directions. These measurements are used to continuously evaluate changes in the asymmetry of the transmission path, and the resulting asymmetry can be used to calibrate the time transfer system.
