Abstract:
1. An apparatus for performing an optical line analysis of continuous data signals, comprising: a phase position processor for computing a phase early/late indicator; a phase control code processor for computing a difference phase indicator; a frequency extractor for computing a low frequency jitter indicator; a statistical calculator for computing a plurality of statistical measures regarding frequency and amplitude components of a jitter of an input continuous data signal, wherein the statistical measures are computed based on one of the phase early/late information indicator, the difference phase indicator, and the low frequency jitter indicator; and a processor for aggregating the plurality of statistical measures and analyzing the aggregated data to detect various failure indicators indicating various malfunctions of the optical line, wherein the optical line is an optical fiber of a passive optical network (PON), wherein the optical fiber connects an optical line terminal (OLT) to a plurality of optical network units (ONUs) through an optical splitter.
