Comparing with passive DWDM-SONET, the throughput of amplified DWDM-SONET using fiber grating-based DWDM-ADM gains much more growth. Although the crosstalk and the amplified spontaneous emission noise are the key factors affecting the performances of network, large node loss can also lead to reduction of throughput and increase of power penalty.
