【 摘 要 】

The paper discusses a new method that combines frequency and phase domains-gated reflectometry. This approach can be applied to a fiber with artificial reflectors to measure the absolute values of optical paths between reflection points in the fiber in the full range of signal frequencies, including zero frequency.
