Market Challenges for Operators

Flat RevenuesFlat Revenues

Increased CostsIncreased CostsLimited BandwidthLimited Bandwidth

�New web-based services drive

bandwidth demand in the access �LTE mobile networks need high

bandwidth for backhaul�50% of the data traffic on AT&T’s mobile backhaul network is iPhone-

generated, despite the fact that only a

few million of their 78 million cellular

subscribers are iPhone users

� Operators want to save money by reducing complexity

of managing multiple networks� Traditional transport technologies are not cost effective

(PDH, SDH)

� Fixed & Mobile convergence will reduce network costs

�Gap between traffic & ARPU� Increased bandwidth requirements but revenues

growth is slow

�Operators are looking for

satisfaction� Offer new services to

Towards More Symmetric & Higher Bandwidth

Higher Symmetric Bandwidth is and will be NeededHigher Symmetric Bandwidth is and will be Needed

� “Legacy” xDSL is bandwidth limited and offers asymmetric traffic with high downstream bandwidth and

limited upstream bandwidth� More bandwidth symmetry is needed

� TeliaSonera considers that in 2010 “typical” digital home, up to 66 Mbps (DS) & 27 Mbps (US) will

be needed.� Online gaming will “balance” the traffic bringing it back to symmetry..

�Some operators even notice higher traffic in upstream than in downstream� In the case of Hong Kong Broadband, the upstream traffic is 3 times higher compared to the

downstream traffic explained by the successful usage of video cameras uploads

Next Gen PON Networks will Reduce TCO and Increase Revenues

�Increased bandwidth will offer new

services and will increase revenues�Higher ports density with higher splitter ratio will offer more subscribers per central

office thus reducing OPEX & CAPEX

�Increased Coverage will reduce the number of Central offices needed in rural areas thus

offering OPEX & CAPEX savings�Operators can close end remove exchanges that will be not necessary: France Telecom could close 95% of its rural COs in Western

France with Long Reach

Which Challenges for Current PON Networks?

Cost per SubscriberCost per SubscriberRegulatory FrameworkRegulatory Framework

�A “one size fits all” regulation is not possible in

Europe �Infrabased competition (“passive access”) is the

prefered solution encouraged by EC �Unbundling is only possible with point to point technologies like VDSL, Ethernet P2P and WDM

PON� Recent regulatory decisions in Big 5 nations

should speed-up FTTx roll-outs

�High cost to deploy PON networks compared to VDSL

with 70-80% for civil works�In Europe, 81% of the FTTH networks are using P2P

technology�GPON is a more cost effective approach

than P2P especially in low density areas

�Duct sharing will decrease the cost of civil works

�Global Warming challenge� The communication industry amounts to 2% of global CO2

emission, according to Gartner’s report� Operators are addressing this issue & ambition to improve

their network energy efficiency:� BT: aims to reduced emissions by 80% before 2016

�Technology Innovations are expected and necessary� Equipment vendors have to increase power savings with

new hardware design and Software features
