Expo Theater I
Massively deployed TDM PON technologies have followed a predictable evolution: ever-increasing speeds from BPON to EPON to GPON and now 10G PONs. The next step in this path will be 25G and 50G PONs. And as with previous generations, there are overlapping standardization efforts in IEEE and ITU-T. Up until now, PONs have been deployed almost exclusively for FTTH. However, the anticipation of 5G densification focuses attention on the mobile transport use case.
Can TDM PONs support the requirements for 5G backhaul, midhaul and fronthaul? Doubts about the suitability for fronthaul have renewed interest in various flavors of WDM PONs. Whether it’s TDM or WDM PONs, will PON transport for 5G be widely adopted? Where and when will PON technologies prove to be the superior to conventional optical and wireless backhaul/fronthaul? How are conventional optical technologies (dark fiber, WDM) evolving to meet the need?
And what about Fixed Wireless Access (FWA)? It never proved to be a threat to FTTH in the LTE era. But with much greater spectrum, in particular at 3.5 GHz and in mmWave bands, 5G (and WiGig) FWA can substantially reduce an operator’s cost and/or speed up their time-to-market relative to FTTH. But is FWA really a viable FTTH substitute, or will it remain a complement? Or both? What are the conditions that make the FWA business case work? And what kinds of operators would deploy it?
This panel will bring varying viewpoints to help sort out the proliferating PON standardization developments, what are the use cases, with particular emphasis on 5G mobile transport, and what are the competing technologies.

Solutions for 5G Fronthaul – a Chinese View
This talk will review both the potential solutions for 5G fronthaul, and their application in the anticipated 5G deployments. The feasibility of TDM, WDM, and Bidirectional fiber will be considered, as well as the assumed demand statistics of the 5G network over the typical access geography.

Optical Fronthaul Applications in Korea’s 5G Wireless Network
This presentation will discuss the application of optics in Korea’s 5G wireless network, which has been under deployment since the fall of 2018 and launched consumer services in April of 2019. Co-existence of 5G with other services on the fiber led to the development of new wavelength plans, which are attractive in other deployment scenarios globally as well.
