First demonstration of secure, AWG performance interrogation using OFDM edge-tones on WDM access networks

Off-the-shelf components have been used to demonstrate, for the first time, non-intrusive C-band port discovery/alignment in arrayed-waveguide guide grating (AWG)-based access networks. MB-OFDM tones in the 3.168 to 3.696 GHz band probed AWG band edges using intrinsic VCSEL tunability.
