400G Transport Extension into Middle-Mile Networks

August 9 – 10:30 am to 11:15 am

The past couple of years have seen a change in the capacity of Dense Wavelength Division Multiplexing (DWDM) platforms going into the network. Service providers are now turning to new 400 Gb/s (400G) per wavelength solutions to increase transport capacity and optimize connecting ports on Optical Transport Network (OTN) aggregation, Layer-2 switching and routing equipment. This move to 400G is not only fundamentally changing the architecture of transport networks, but it is also likely to find extensive use in middle-mile networks as the transformation of broadband access networking takes place.
This session will:

  • Review the role middle-mile networks play in broadband access transformation;
  • Present the requirements of middle mile networks;
  • Explain the transition of transport networks from 100G to 400G;
  • Examine potential middle-mile architectures equipped with 400G transport.
