4Multiple Access Network Architectures
- Fiber to the Premises (FTTP)
- Shared 2.4 Gbps (GPON)
- Eliminate actives and copper from the OSP
- Triple-Play (High Speed Internet, Voice, Video)
- Fiber to the Curb (FTTC)
- 80-100 Mbps per subscriber
- Reuse existing copper drops
- Triple-Play (High Speed Internet, Voice, Video)
150 Meters
- Fiber to the Node (FTTN)
- Least expensive initially, but
- Least bandwidth capable up to 24 Mbps
- High Speed Internet and Voice
ADSL2/ VDSL2
1,500 Meters
5Why FTTP at Verizon?
- Concept of FTTP finally became feasible
- Technology matured for potential economies of
scale - Residential broadband market has taken off in
terms of penetration and bandwidth demands - Regulatory reform in the local loop
- FTTP chosen over FTTN, FTTC, WiMAX
- Greatest flexibility and potential
- but Wall Street reaction has been tough
- FTTP is now the core element of Verizons future
strategy - Largest project Verizon has ever undertaken
modernization of the Local Loop into the 21st
century - A revamped network to support triple-play to
residential and small business customers - Replaces copper in the last mile with
future-proof technology - Passive network drives large savings
Verizon will not be beaten on Bandwidth
6Verizons FiOS Strategy and FTTP Results

- 50B Voice/Data/Video Market in Verizon Footprint
- 725K Internet Subscribers in 16 states in 2006
- Penetration rate
- 6 months 8
- 9 months 12
- 12 months 15
- Churn-rate is lt1.5

8Bandwidth Demands per Home
- Carriers are planning for up to 100Mb/s in the
future - HDTV adoption is occurring at a rapid pace
HDTV set sales saw strong growth during the
holiday season. U.S. retailers sold about 750,000
HDTVs between Thanksgiving and Christmas, or
about 26 of total TV sales in 2005, up from
about 360,000 in the 2004 period, or 13 of all
TV set sales that year, according to retail sales
tracker NPD Group Inc.
9Bandwidth Demands per Home
Multiple video streams means gt24 Mbps required
10High Level Challenges and Opportunities
- Bandwidth demands are increasing
- Video, differentiated video services, Mobile
Video, Personalization - High speed Internet, Bandwidth Intensive Gaming
are key drivers - Convergence of Video, Data and Voice
- FTTN and deeper DSL offer least expensive upgrade
path - To deliver higher speed Internet and voice
services, but - Are inadequate for future video evolution
- FTTP/PON is cost-equivalent to copper in
Greenfield applications - FTTP/PON is an effective competitive
differentiator - FTTP/PON network has numerous benefits
- High bandwidth for triple-play services including
video - Reduced OPEX with elimination of actives and
copper - Improved customer satisfaction with ONT
intelligence

13Long-Term Maintenance Reduced Opex
- Main FTTP savings areas
- Repair routine maintenance
- Eliminate copper active components with FTTP
- Copper line maintenance costs can be up to 100
annually per line - Intelligent ONT end-point
- Remote monitoring, testing troubleshooting
- Auto-discovery system inventory
- Automated service modification
- Increased satisfaction by pre-setting customer
expectations - Customer-chargeable event like indoor wiring
- Non-chargeable event

16FTTP Capex Opex Breakdown
- Installation labor typically most significant
cost - Electronic equipment costs 2nd
- Roughly 75 CPE to CO
- Variables can affect this including
- Subscriber penetration
- PON fill rate and split ratio
- IPTV vs. CATV
- TDM voice vs. VOIP
- Outside plant varies by design
- Aerial generally less than buried but
- Aerial generally higher annual maintenance costs
Capex Opex savings easiest to find here
17FTTP Industry Challenge
- Reduce installation labor (time and costs) while
- Developing delivering cost-effective ONT FTTP
equipment - Improving customer satisfaction, loyalty and
retention rates - Reducing annual maintenance costs
Largest avoidable cost for an FTTP network is
rolling a truck twice
18Labor Challenges
- Installation cost can be 40 of total cost per
subscriber, including fiber plant electronics
19ONT Product Definition

- Battery Backup Unit (BBU)
- Full telemetry support
- E.g., battery discharging
- Telephony
- E.g., draw break dialtone test
- Video (CATV)
- E.g., input output transmit power level

27Conclusions
- Controlling Capex Opex in FTTP networks is
essential - Installation labor costs are the biggest category
- Intelligent ONT FTTP equipment designs can
reduce installation labor costs - EMS diagnostics are critical to customer
satisfaction eliminating unnecessary end-user
site maintenance costs - FTTP with PON delivers significant operational
savings
