Abstract
An optical communication fiber link including a monitoring system connected to an optical fiber transmitting electromagnetic radiation including a communication. The monitoring system includes a detection system detecting a scattering of the electromagnetic radiation from the optical fiber. The monitoring system monitors the scattering for an abnormal change and determines, from the abnormal change, an absence or a presence of a fault in the optical fiber.
Claims21
An optical communication fiber link, comprising:
- a monitoring system connected to an optical fiber communicating a signal, the monitoring system:
- detecting a scattering of the signal from the optical fiber and detecting reference data from the signal, each separately provided from the optical fiber to the monitoring system;
- monitoring the scattering for a change using a comparison to the reference data;
- and
- determining, from the change, an absence or a presence of a fault in the optical fiber.
A method for on-line monitoring of an optical communication fiber link, comprising:
- detecting a scattering of a signal and reference data in the signal from an optical fiber;
- separating the scattering of the signal from the reference data;
- and
- determining an absence or a presence of a fault in the optical fiber based upon a comparison of the reference data to the scattering of the signal.
