Theoretical Method of PON Reflectometer Trace Analysis
The difficulty in analyzing a PON network is directly linked to the
use of the splitter. When a splitter is used, analysis of the
backscatter response after the splitter is necessary. Figure A.3
shows a PON reflectometer trace analysis of a simulated network
with one splitter. The splitter can have any number of branches
with fiber of different lengths. Figure A.4 shows the PON
reflectometer trace given by the OTDR of a simulated network
with one splitter.
