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

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
