Fibre to the MDU Presentation Cabling Issues

MDUs are a significant opportunity for infrastructure providers � UK Dwelling Unit number increasing, 7.7m at 20 th Century start to 26.2m by 2008 � In excess of 4m flats/apartments in England alone � Number of DU’s is increasing at steady rate of > 250,000 pa. Exceeds new build – New flat build and flats from sub-division (20% of all flats)

Specific MDU Challenges

Ownership Fragmented Ownership � BTL, small registered landlords Lack of templates and standard Geographically diverse Trade Body? FLEXIBLE, EASY DEPLOY SOLUTIONS…….

Noise and disturbance of inhabitants Depending on MDU type Impact varies: -Leasehold flats -Retirement flats -Part occupied -New Build -Converted Housing

New developments

There are different ways to cable an MDU

Home Run

Splice/Split on the floor

Pull-back method

Deciding between the alternatives

Installer skills set

System A splice box can be added in Option 3 Enables cheaper riser cable to used � Allows for a flexibility point on the floor � Second split location option available

Cost Comparisons Assumptions: � 1 or 2 fibre to each user as stated � Cost includes ONLY in-building cabling (not OSP cable) � Standard floor height for buildings (3m?) � Apartment horizontal spacing (4m?) � Cable run in apartment to ONT 5m. � Labour rates approximated to UK professional electrician rates (£20/hr?) � Component costs – based on m2fx items. Other vendors will differ.

Costing Observations

MDU Cabling Conclusions � There are 3 main alternatives – Numerous versions of each (pre-term, split) � The factors to consider are: – Built Environment: Retrofit or New Build – PON versus P2P – Skill levels of deployment teams – Cost � Costs: Depend on building horizontals and local labour and component costs
