摘要： An optical fiber link monitoring apparatus for detecting a failure in an optical fiber link by analyzing a trace of a received signal that has been transmitted to and reflected from said optical fiber link. The optical fiber link monitoring apparatus includes a variable gain amplifier (VGA), an analog/digital converter (ADC), and a controller. The VGA amplifies a gain of the received signal, for which the ADC converts the gain-amplified signal into a digital signal. The controller then analyzes a digital signal trace and adjusts the gain of the VGA according to the analysis result.
