Fibre to the MDU Presentation
Cabling Issues
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)
Specific MDU Challenges
Ownership
Fragmented Ownership•BTL, small registered landlords
Lack of templates and standard
Geographically diverse
Trade Body?
FLEXIBLE, EASY DEPLOY SOLUTIONS…….
Access
Churn
Cost
Aesthetics
Fixtures and Fittings
P-Clips Pinned or self-adhesive trunking
Existing UPVC electrical conduit
Fixing Methods still traditional Fixing Methods still traditional
Fire performance
Currently discretionary
To follow the EU CPR:
Harmonised EN 50575 (2015?)
EN 60332-1-2EN 50399EN 61034-2EN 50267-2-3
Categories to be established
Noise and disturbance of inhabitants
Depending on MDU typeImpact 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

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
