  1. Fred Leonberger CIPS High-Capacity Backhaul in Advanced Wireless Networks: the PON SolutionIntroduction

  2. Center for Integrated Photonic Systems • Institute-wide community of researchers in integrated photonics and systems • Research focus ranges from materials and devices to systems and economics • Varied major activities • CIPS Annual Meeting • MIT/Industry Working Groups • Affiliation with other MIT consortia

  3. CIPS Optical Broadband Working Group Activities • Focus on next-gen PON architectures and enabling components • Monthly meetings, semi-annual workshops • Cross-value-chain industry participation • Wide range of expert guest speakers • White papers • Analysis of drivers, barriers and recommended actions for next-gen PONs • Identification and study of key research topics • OpEx and CapEx modeling of FTTx options • Process-based cost modeling of key components • Investigation of key limits/issues for XG-PON
