Abstract
Official abstract text for this publication.
There are provided a device for monitoring an optical link fault and a method thereof. According to an embodiment of the invention, the device for monitoring an optical link fault and the method thereof apply an optical link fault monitoring signal to an optical link and precisely identify a type of the fault using waveforms of a reflected signal returned from the optical link or a wavelength dependence of reflected signal intensity.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of monitoring a fault of an optical link in an optical fiber, comprising: applying an optical link fault monitoring signal to the optical link, measuring optical intensity of a reflected signal returning from the optical link, and obtaining a trace; determining a number of waveforms of the reflected signal; determining a default number of waveforms of a default reflected signal, which is the reflected signal when the optical link is fault-free;…
