Video is the main driver for access bitrate requirements

• Video / image up-/ download (YouTube & Co.)

• Video-related cloud services16Home HD Video

What kind of video?


Summary bitrate drivers• “Video” is more than just TV

• Video related applications and services (“Visual Networking”) will determine access bitrate requirements

• Need to support multiple video applications concurrently in a household

• Content will become more and more “high definition”

• Majority of applications require symmetrical access bitratesor at least better upstream service

• Both sustainable bitrates for streaming video as well as high peak bitrates for transfer of large (video) files are required

• 2001 ~ 25kbps per user peak average

• 2011 ~ 125kbps per connection peak average


Nielsen’s law: exponential access bitrate growth

High-end users’ connection speeds grow >50% YoY

Mass market lags high-end by 2...3 years

How do you determine the right FTTH access topology?Understand your options for the deployment of fiber in various topologies

• Which business models do you plan to implement today?

• Which business models do you plan to implement in 20 years from now?

• Are restrictions for the deployment of certain topologies based on

serious analysis of the existing infrastructure (e.g., ducts), conservative assumptions, or driven by considerations to enable / prevent certain business models?

If your access infrastructure needs to be flexible, business model and technology agnostic, then deploy point-to-point fiber

17


How do you determine the right FTTH access technology?Understand your options for the technologies to be used over the fiber topology

• Which peak bitrates will your customers require over the lifetime of the technology (e.g., 5 years) which you deploy today?

• Do you want to differentiate technologies between low-tier and high-tier residentials, SMEs, enterprises?

• Can you distinguish locations of these different types of customers?

• Is a unified approach simpler and cheaper in the end?

• Do you want to be on par with the most successful FTTH deployments in Europe?

If your technology choice needs to be equally suited for all types of customers, be highly scalable, mature, secure, then deploy Ethernet

Summary• Video-related applications and services continue to drive

exponential access bit rate growth

• Applications increasingly require ultra-high-speed symmetrical connectivity

• A new fiber plant is the most valuable asset, think long term

• Ethernet is the clear choice of virtually all major FTTH deployments in Europe
