Regulatory Framework
Regulation vs. Public policy
A stable and predictable regulatory and public policy environment is key to enabling FTTH investment
The current Regulatory Framework is being reviewed – to conclude in Summer 2008?
We are pleased to see that Next Generation Access (NGA) is a major component of the Review
We believe a strong pro-investment NGA based on FTTH position needs to be further developed

Outside plant challengesCivil costs are still prominent in most projects varying from 65 to 85%
• The costs for civil vary between the European countries from about €15/m to €125/m
• The rules regarding rights of ways are different between the European countries
Speed of the roll-out defines the success of the business planSpace limitations within dense cities to build larger POPs Larger scale compressed roll-outs do result into disturbing the city live through traffic issues

In-House challenges
New MDU• The Fiber cabling needs to be
foreseen during the planning phase of the architecture and the landlords need to be convinced from day one
• The cabling system needs to be protected during the building of the in-house infrastructure
• The cabling system needs to become an easy to install solution enabling lower skilled labor to be used
Existing MDU• Customised solutions for the
different buildings need to be engineered.
• Each building requires a site survey prior to installation
• The cabling solutions needs to be prepared both to connect the customer on day one and the future customers
• MDU - (Multi Dwelling Unit)

Innovation
NEXT GENERATION ACCESS SYSTEMCombination of the advantages of
• Tube-system• Direct buried cable• In-house cabling
integrated into one product offering
Our goal with this system is:
Reduction of the costs for installation byreducing the requirement for highly skilled resources

Next Generation Access Cabling SystemNext Generation Access Cabling
Benefits:• Reduction of the required skilled human
resourcesNew development of blowing process → higher pressure → longer distancesNo splice point at the building inlet → reduction of the number of splices (-40%)
• Direct buried (no blowing process needed)• Homes past with pre-installed or empty tubes
possible (possibility to blow in the cables)• Possibility to change the material of the tube in
the in-house area (to LSOH)• Bending insensitive through cable construction
supported with G657 fiber
