How 1Tb/s Might Look… Conventional WDM vs FlexChannels Conventional Per-Channel WDM Filtering 1Tb/s Guard bands allow for individual wavelength demux Limits channel density and fiber capacity Limits data rates by limiting available spectrum for modulation bandwidth Multi-Carrier FlexChannel 1Tb/s Tighter spacing, or higher data rate per channel ( FlexCoherent) Up to 25% increase in useable amplifier spectrum Simplified optical switching of FlexChannels with broader spectrum
