Next GenerationArchitecture’s Readiness

for the Next Generation Broadband

Technical Review

• Next Generation Architectures

– Fiber Concepts are Changing

» Are we prepared?

– IP Applications and Services

» Anything New?

– Passive Optical Networks Defined

» Not Just P2MP anymore.

– Video

» Beyond IP and HDTV

– New Bandwidth Requirements

» Can the existing networks handle it?

Important Concepts - Deployments for the Access Networks

• Design process for access solutions over fiber begin in the CO/HE, moves thru the Optical Distribution Network and terminates at or near the subscriber’s premises. Design for the SA is key.

Next Generation Application Support

• Conservative estimates place the physical infrastructure of the fiber network with a 20-35 year life expectancy.

• The current generation of access electronics is estimated to have a life cycle of 3-5 years. Up to 100Mbps today, 1-Gbps tomorrow.

• Proper fiber techniques will provide for the a smoothly run network today and a foundation for the transition between the current generation of access electronics and the next.

What, When, Where, & How

Multiple Screens For: Video Entertainment, Phone Calling, Video Calling & Messaging

Single Identity: Inbox/Address Book/Billing; Cross Functional Devices With Presence

Multiple Devices – Multiple Platforms – Service Creation

• xDSL – Technology Available and Mature ADSL 2+ Rate & Reach: 26 Mbps, 1 – 1.5 km VDSL Rate & Reach: 100 Mbps, 300m – 1 km VDSL2 Promises 100 Mbps+, 100m – 300m Advantages: Uses Existing Copper Get to the Customer Early Disadvantages: Will not support Video Overlay Limited support for multiple HD Video over IP Channels

VDSL2 Availability (Require Clean Copper)

• Metro Ethernet – Technology Available and Mature Fiber EPSR Rate & Reach: 1, 40, 100 Gbps, 100 km Fiber to the Home Rate & Reach: 100 Mbps for 10 km Advantages: Ethernet Protection Switching Rings Fiber to the Home Interface Ports Disadvantages: Will not support Analog Video Overlay Expensive SFPs & Components

Copper/Active Solutions – Current Availability

PON Architectures – Current Availability

• GEPON, GPON, NGPON – P2MP Technology Available and Mature

GEPON Rate & Reach: 40 Mbps, 20 km GPON Rate & Reach: 80 Mbps, 20 km NGPON Rate & reach: 300 Mbps, 20 – 40 km WDMPON Rate & Reach: 100-1000 Mbps, 20 km Advantages: Video Overlay Supported Extended Rates & Reaches Supported Additional Split Ratios Supported Disadvantage: Shared Bandwidth WDMPON Costs/Footprint

• EFM – P2P Technology Available and Mature Fiber Rate & Reach: 100 Mbps – 1 Gbps, 10 - 20 km Advantages: All IP Format Up to 1 Gbps Speeds Disadvantages: Second Fiber to support Analog Video Extensive Fiber Needed in the CO & OSP

POI

• We design and build using methods and procedures

(MOPs) that provide a way of benchmarking.

• We need to take some of the responsibility of the design out of the hands of the engineers by using processes that are controlled by manufacturing.

Network Design – Guarantees - Controls

How can we guarantee that the network we design is correct?

There are certain design aspects that we can control.

• Understand the kind of customers. • Understand the services today and tomorrow.• Understand the timeline for growth and scalability.
