  • Description

    It is anticipated that new use cases will become the main drivers behind the need for emerging PON technologies. Applications such as mobile front haul (MFH) and mobile back haul (MBH) for 5G and future 6G networks will require PONs with capacities well beyond those outlined in the ITU recommendation on Higher Speed PONs. The conventional IM/DD approach based on NRZ is already close to its limits in terms of launch power levels or receiver sensitivity, motivating research into new directions in order to reach network throughput beyond 50 Gbit/s per wavelength. The workshop covers these topics with two sessions of presentations. The first session will discuss solutions to further scale throughput and improve operational aspects using existing IM/DD approaches. The latest recommendations for Higher Speed PON will be presented covering 50G upstream challenges and limitations, as well as TWDM evolution and use cases. In addition, the evolution of IM/DD PON systems will be discussed including: how to bring flexibility in PONs, DSP energy consumption considerations and possible developments in advanced DSP. Insights on future PONs based on new transceiver architectures will be presented in the second session, which will explore advances at the device and sub-system level that are required to increase PON capacity to beyond 100 Gbit/s per wavelength. The discussion will also consider how technologies developed for data centre and metropolitan networks (integrated photonics, coherent transmission, multi-carrier systems, DSP, etc.,) can be adapted for PON applications.
