SC485 - Advanced Fiber Access Networks New Cancelled

Sunday, 08 March
09:00 - 12:00

Short Course Level: Advanced Beginner


Cedric F. Lam and Shuang Yin, Google, USA

Short Course Description:

This short course will start with explanations of operators’ pain points in operating a broadband access network and how fiber access networks helps operators to solve their problems and evolve their businesses.  Instead of just going through various PON standards and their implementation details, this course will look at fiber access networks from the perspective of a complete end-to-end operator network and explain the technology choices in relation to the challenges faced by operators.


The following topics will be covered in this short course:

  • Quick review of various fiber access architectures and the mature PON standards
  • Drivers for fiber access network evolution
  • Advanced PON standards: 10G, 25G, 50G, 100G and beyond
  • WDM in fiber access networks
    • ITU-T NG-PON2
    • IEEE 802.3cs Super-PON
    • ITU-T G.metro
  • Coherent PON networks
  • Photonics technologies and implementation challenges for next generation PONs
  • DSP in fiber access networks
  • End-to-end fiber access system & network scaling
    • OLT, BNG, edge cache & computing
    • Network traffic characteristics and their effects on network system designs
    • Open OLT and disaggregated PON network systems
    • SDN in access network and ONF CORD/SEBA effort
  • Converged fiber/wireless networks
    • Fiber access networks in 5G wireless network applications
    • Gigabit fiber access networks vs. gigabit 5G wireless access networks
Short Course Benefits:

  • Describe architectural and traffic characteristics of modern broadband access networks
  • Explain the techno-economic challenges faced by broadband network operators
  • Identify the scaling bottlenecks (transmission or bandwidth) in end-to-end operator broadband networks
  • Explain the challenges and enabling technologies (photonics & DSP) for implementing next generation fiber access networks
  • Apply SDN and datacenter techniques to build more scalable and cost-effective fiber access networks
  • Design fronthaul and backhaul links for 5G wireless networks
  • Compare and contrast broadband fiber vs broadband wireless access networks
Short Course Audience:

This course is an advance level course.  Basic understanding of the FTTH technologies especially PON (Passive Optical Network) is expected in order for the audience to follow the materials.  This short course is intended for researchers and graduate students working on broadband access networks, product designers, network architects and practice engineers from internet service providers and equipment vendors,

Instructor Biography:

Cedric F. Lam
Cedric Lam was co-founder of Google Fiber which changed the landscape of broadband access networks in North America with the introduction of nationwide Gigabit FTTH networks.  Cedric has experience both in product development and in engineering service provider networks.  He started his career with AT&T and later joined Opvista, a startup company building high capacity optical transport equipment, as chief system architect.   After Opvista, he joined Google to work on datacenter networks before embarking the effort on Google Fiber, where he is now Engineering Director, leading the Architecture and Device Engineering team.   He is a member of the CORD Technical Steering Team, and Fellow of OSA.  He also edited the first text book in PON: Passive Optical Networks, Principles and Practice, Academic Press, 2007.
