Communication service providers are adopting a range of approaches to 5G. Some are focusing on fixed wireless access as a substitute to copper or fiber transport. Others see huge opportunities in accessing sensors with new narrowband radio access technologies such as NB-IoT and LTE-M. There is also great value in end-to-end virtualization, aka slicing, for offering customized private mobile networks to enterprises and governments ...

I first came across the reference to Super-PON back in 1996 at an IEEE Communications Society Conference. At that time, Super-PON was described as supporting a split ratio of 1:1024 at a range of 100km. The overall network capacity of the Super-PON was 2.5Gbit/s TDM downstream and 300Mbit/s ATM-based TDMA upstream and it introduced the concept of optical amplifiers along the fiber paths. At the time this was particularly forward thinking, as the only PON systems that had been deployed were BPON systems supporting a split ratio of 32 subscribers and a capacity of 622Mbit/s / 155Mbit/s. For reference, GPON can support a split ratio up to 1:64 at a range of 20km with a network capacity of 2.5Gbit/s / 2.5Gbit/s ...
