Cabling Issues
SLIDE 2 MDUs are a significant opportunity for infrastructure providers
UK Dwelling Unit number increasing, 7.7m at 20th 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)

- Leasehold flats
- Retirement flats

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.

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
