1) The document discusses how service provider transport networks are undergoing radical changes as traditional networks are no longer sustainable. 2) Optical network choices have long-term cost impacts, and total cost of ownership is impacted by technology and network architecture. 3) The optical network is at an inflection point, driven by innovations like flexible grid, flexible coherent modulation, multi-carrier superchannels, and photonic integrated circuits. This enables scaling of optical layer capacity to terabits.

 Fixed 50GHz grid (ITU G.694.1) works well up to 100G
• Compatible with legacy WSS ROADMs
• But 25% wasted spectrum due to guard bands
 What about super-channels (e.g., 1Tb/s PM-QPSK)?
 Flexible Grid enables 12.5GHz granularity & single pool of capacity
 Driver for flexible OTN containerization & circuits (OTUadapt, ODUflex)
