In the first solution, a conventional optical time domain reflectometry (OTDR) and a switch unit are employed, while in the second method, a novel architecture based on N×N arrayed waveguide grating (AWG) is proposed.
Both methods are able to localize failures in feeder fiber and drop fibers without e.g. using expensive tunable OTDRs.
Furthermore, VPI is examined in terms of its future applicability in modeling complete PON supervision methods based on OTDR.
Fiber access networks, wavelength-division-multiplexed passive optical network (WDM PON), supervision, optical time domain reflectometry (OTDR)
For TDM-PON supervision, an optical time-domain reflectometer (OTDR) is typically used.
