FTTx Access Architectures

What Drives Access Architecture Decisions?– Bandwidth demands– Political/Regulatory requirements– Time to market constraints– Competitive threats– Capex Constraints

Access Architecture Options– Fibre to the Premise (FTTP)

– GPON– Active Ethernet

– Fibre to the Curb (FTTC)– Fibre to the Node (FTTN)

– ADSL2+– VDSL2– Bonded xDSL

– Fibre to the DP (FTT-DP)– Ultra Broadband Ethernet

Bandwidth Drivers: Internet Traffic

Global Internet Traffic: 40% (CAGR) from 2008 -2013

Bandwidth Drivers: IPTV

High-definition video and ultra high speed Internet services raise the benchmark for bandwidth requirements in the access network.

3D TV will drive bandwidth requirements higher

Changing the Total Cost of Deployment

• Deployment is greatly simplified using OSP DSLAMs– No new right of way– No new pad work– Significantly lower shipping costs– Installation doesn’t require a crane– Smaller crew onsite for installation– No expensive heat exchanger

solutions– Lower power requirements

• Electronics costs keep falling but total deployment costs aren’t getting any cheaper– Metal (i.e. cabinets) keeps climbing– Lower density areas can’t prove in

due to first cost turn-ups

What Vectoring Provides? – Eliminates self cross-talk on

short copper loops– Significant gains on short loops

(<1Km)

Deployment Guidelines for Vectoring– Short loop nature of this

technology leads to smaller node sizes

– Need small-form-factor, remote DSLAMs to take advantage of cross-talk cancellation capabilities of vectoring

Advancements in FTTN: VDSL2 Vectoring

VDSL2 with vectoring is ideally suited for remote node deployments

23® Adtran, Inc. 2008 All rights reserved

Can Telcos be competitive with copper?

With Vectored VDSL2, 100 Mbps is possible on 2-pairs– ~2500 ft of 26 AWG PIC– ~3200-3500 ft of 24 AWG PIC

Complexity: Cost and Power– Estimated 10% adder for small vector group

sizes 48 ports– Up to 30-35% for larger vector group sizes

(192 ports) Still much less expensive than an

additional pair or more DSLAM locations

– Distribution area studies show that desired vector group size is >48 lines

Fiber to the Curb (FTTC)

Total Access 1108VP– 8 Ports of VDSL2+POTS– Chaining of multiple units

along a fiber route– Full video support– Fully sealed for above or

below ground deployment– Remote powering– Small form factor (10” W x

15” H x 4” D)

Ideally suited to fill in the coverage gaps with FTTH Networks

27® Adtran, Inc. 2008 All rights reserved

Operators’ Competitive Landscape

100Mbps is the next speed milestone – numerous national goals DOCSIS 3.0 means 100Mbps over cable is here today FTTH overbuild still requires significant capital and

installation expense (and time) FTTH is impractical and expensive in some installation

situations – the customer cannot be profitably connected Telcos need a way to serve those customers with Fibre

services but with reduced cost and installation time

Ultra Broadband Ethernet

•No Fibre trenching through asphalt/concrete to each home•1 central ONT instead of 8 individual ONTs•No Truck Roll to household for ONT install•No truck roll to wire up Ethernet in home•Ethernet over existing copper, specialised packaging & power distribution make it all work

Ultra Broadband Ethernet – a new solution category that can provide Fibre services into areas where FTTH is not practical or cost-effective– ~Half the cost of FTTH deployment is to connect a subscriber

already passed by Fibre– Can turn telco into landscaping company!

Leverages existing copper and new technologies– Uses existing drop pair from distribution point (pole, pedestal,

footway box, MDU frame) to subscriber premises– New 100Mbps symmetric Ethernet over a single pair: Fibre fast at

a fraction of the cost

Ultra low power– Green technology (~1W per subscriber)– Powered by subscriber – lower capex and opex

UBE: What is it?

33® Adtran, Inc. 2008 All rights reserved

Ultra Ethernet Meets the aggressive goals

Fast Downstream: Minimum 100Mbps Fast Upstream: Minimum 100Mbps Low CAPEX & OPEX:

– leverages existing copper pair & self install– No maintenance – install it and forget about it– Low cost CPE option – simple media adapter

Accelerate Revenue: hours not months– No Fibre trenching and network power delays– Self install

Flexible– Very small, sealed and submersible – install anywhere– Can leverage GbE, GPON and Active Ethernet on uplink– Small port granularity (8 port)

Ultra Green: ~1W per subscriber

Summary

37® Adtran, Inc. 2008 All rights reserved

A toolbox with all the right tools

• ADSL2+: basic internet access & SD video - Can’t do 100Mbps

• FTTN w VDSL2: – Up to 100Mbps DS, 50Mbps US (1,400 ft to 2,700ft depending on

vectoring and bonding)– Appropriate for cross connects with short loops

• FTTC: – Appropriate for Greenfield in certain cases

• FTTP: Greenfield and select brownfield– Can easily do 100Mbps and beyond– Only cost effective in greenfield or certain brownfield scenarios

• Ultra Broadband Ethernet (cont’d)

38® Adtran, Inc. 2008 All rights reserved

Con’t

Ultra Broadband Ethernet– Brownfield region where fibre installation is difficult super fast internet is desired but FTTP doesn’t prove in due to

high cost of fibre installation– Highly competitive region where time to market is critical Regaining a lost customer is very expensive. Ultra Ethernet

can be deployed quickly and tactically as defense against cable providers

– Where likely take rate is uncertain Can deploy an 8 port Ultra Ethernet solution for same price as

one FTTH customer!– Multi-dwelling units: leverage existing wiring and capitalize on self

install advantage– Others?
