Global Fibre to the MDU

Drivers

�Carrier Investment to Profit from Increasing Bandwidth Demand� Future proof solution is mandatory� New applications (e.g. 3D, Super HD video, etc.) will mean fibre to

building is not sufficient. Fibre to the Unit will be needed

�Regulator influence and competition� Multiple deployment models - Each can drive different fibre

infrastructure needs!

�Government driven Broadband stimulus

Global Consensus: Fibre to the Home (and each MDU Unit) is becoming mandatory to support valued applications and be

globally competitive

�� ! �"��#��#�� %


Challenges

�Cost – greater concern due to Global Financial Crisis and Competition� Increased scrutiny of deployment cost – particularly first cost � MDUs using conventional cable solutions can cost 50% more to pass than SDUs

�“Broadband Divides” – some areas will get fibre first� Favoured – Greenfield and Affluent Areas� Challenged - Brownfield – most MDUs and less affluent areas� Government / regulator intervention to ensure opportunity for equal access to all?

� Lower cost approaches required to deploy Fibre to MDUs in a variety of building structures and regulatory environments � Optical Networking Units are decreasing in cost (and size!)� Consider all passive components and supporting installation hardware� Consider time to deploy

�� ! �"��#��#�� &

Deployment ExperiencesFocus on New Options

�� ! �"��#��#�� '


Deployment Considerations

�Greenfield� Makes sense. Put in best option from day 1 as you build, i.e. fibre! � Requires co-ordination with builders and utilities – who pays for what?� Slowdown in new house building, but signs of new starts?

�Brownfield� Ownership structure of buildings� Access to buildings, types of building and infrastructure� Availability and skills of installers – will impact on volume deployments.

�Providers wants / needs� Flexibility – grow and connect on demand� Reliability – works first time, no repeat “truck rolls”� Speed of deployment – numbers will be huge when the tipping point reached.� Cost effective – right balance of speed, cost, reliability and performance.

�European situation is similar to the rest of the world

Connectorization in the MDU - Mechanical Splice ConnectorsFirst in APAC, spreading now to NAR, EMEA.CALA

1. Fibre is prepped and cleaved while in the fibre holder.

2. The fibre remains in the holder during insertion to maintain proper angle alignment.

3. The wedge is released and installation is complete.

Over 10M in service in Japan supporting FTTH installations since 2004~ 1 minute installation time!

Lessons Learned and Provider Needs

�� ! �"��#��#�� !*


Lessons Learned and Provider Needs

� Flexibility – Lowers cost by supporting many building types, pathways, regulations - no one right way!

– Must be able to grow and connect on demand– The right combination of multiple solutions needed for each provider that are

adaptable to the deployment requirements.

� Reliability – Lowers cost - works first time, no repeat visits.– Wider deployment of bend optimized fibres – G.657.A1 types very widely accepted.– Use of G.657.A2 and/or G.657.B3 fibre types depends on:

� Infrastructure, Speed / skill of installers, risk tolerance– Corners driving increasing use of G.657 B3 fibre

� Eliminates protective trunking saving $20 to $40 per unit.

� Speedy Deployment – to faster revenue at lower cost, an increasing need with competition and volume deployment.

– Growing use of pre-connectorised solutions for final connect.– Faster / easier field connection methods. – Many inputs which determine choice.
