Good News: Broadband Data Demand Keeps Rising
• Global broadband subscription growth will slow but average broadband speeds will rise sharply:• Global average broadband rate to
increase 540% between 2017 and 2024
• Average broadband rate in 2024 to exceed 270 Mbit/s
• Broadband data rates in some developed regions will be much higher than global averages: • Hong Kong to hit 460 Mbit/s by 2024

Disaggregation Defined
• The separation of networking equipment into functional components and allowing each component to be individually deployed:• Encompasses separation of software OS from
underlying hardware• Requires open APIs to enable SDN control
• Degrees of disaggregation exist• Vertical vs. horizontal disaggregation• Not one size fits all in the market
• White Box is a specific subset of disaggregation that requires open spec hardware produced by contract manufacturers• White box has its own benefits and challenges

Industry trends and Operator challenges - FTTx
Trends
• Demand Growth faster than revenues
• Technology convergence for open technologies, tools as alternatives to proprietary technology
• Value generated by OTTs, Cloud players and ecosystem players
Challenges
• How much to invest for increasing demand - fatter pipes, networking services
• What is the right architecture, also how easy is it to deploy
• Finding the sweet spot for value creation with lower capex and opex investment and execution of right architecture
