COHERENT OPTICAL MEASURING DEVICE, OPTICAL LINE TEST SYSTEM AND METHOD - A simplified explanation of the abstract

This abstract first appeared for US patent application 18275848 titled 'COHERENT OPTICAL MEASURING DEVICE, OPTICAL LINE TEST SYSTEM AND METHOD

Simplified Explanation

The present disclosure describes an optical line test system that detects loss points along an optical line by applying vibration and using a coherent light measurement device to identify corresponding vibration points.

• Coherent light measurement device is used to detect loss points along the optical line.
• Vibration is applied to the facility on the path of the optical line.
• Vibration points of the optical line are detected using the coherent light measurement device.
• Loss points are identified based on the correspondence between detected loss points and vibration points.

Potential Applications

This technology can be applied in:

• Optical network maintenance and troubleshooting.
• Quality control in optical communication systems.

Problems Solved

• Efficient detection of loss points in optical lines.
• Improved accuracy in identifying issues along the optical line.

Benefits

Original Abstract Submitted

The present disclosure is an optical line test system that detects a distribution of loss points of an optical line in a longitudinal direction, using a coherent light measurement device, applies vibration to facility disposed on a path of the optical line, detects a vibration point of the optical line in a longitudinal direction upon applying the vibration, using the coherent light measurement device, and identifies the loss point based on correspondence between the detected loss point and vibration point.
