Performance evaluation of O-band OADM-based optical distribution networks at 50Gb/s and 100Gb/s PAM-4

We assess the performance of transparent and data-rate adaptive aggregation network with cascaded O-band OADM nodes. Experimental results show transmission of single-wavelength pluggable 100Gb/s Ethernet traffic and 50Gb/s PAM-4 SER with power penalty < 3dB and 2.5dB across 2 and 3 nodes (30km and 40km), respectively.
