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.
, arrayed waveguide grating (AWG) (see Fig. 1.3), in the remote node.
*Compared with TDM-PON [12], the significantly reduced insertion loss of the remote node in WDM-PON (i.e. 3-5 dB caused by AWG) helps to improve the power budget as well as increasing the transmission distance [11].
AWG) and the monitoring devices (including OTDR and Optical Frequency Domain Reflectometry, OFDR) are studied in this stage.
First, several important components for PON supervision, e.g. arrayed waveguide grating (AWG), optical time domain reflectometer (OTDR) and optical frequency domain reflectometer (OFDR), are introduced in subchapter 2.1.
