1 The Role of GPON In Supporting Triple Play Services Ralph Ballart Globecom 06 November 29, 2006

2 Agenda! Introduction! New Video Paradigms! How Much Bandwidth Is Enough?! VDSL2! Gigabit Passive Optical Networking (GPON)! Summary Globecom 2006 Date Page 2

3 Many Factors are Driving a Tectonic Shift in Communications, Entertainment, and Technology 1. Service Providers deploying Triple Play (e.g. via PON)! Driven by protection of the embedded base, the top line, and shareholder value 2. Favorable regulatory environments! Cable franchise relief, municipal broadband relief 3. Introduction of Over the Top Internet video providers! The subscriber as both a video consumer and a source 4. Mobile carriers trying to grow ARPU T H E I N T E R N E T Globecom 2006 Date Page 3

4 New Communications Mechanisms Based on IMS and P2P.creating even more choice, consumption, and disruption Remote DVR Control Mobile Video Broadcast Call Management Integrated Mobile Messaging Mobile VoD Globecom 2006 Date Page 4

5 The Broadcast Entertainment Market Potential Viewers As content increases viewers decrease Content Films Sports Soaps City TV Niche / Genre TV Home Shopping Community TV Dedicated Subjects Sports Club TV Friends TV Family TV Something other than broadcast will drive communications usage.

Cost effective high capacity, high availability MPLS based Ethernet Service Switches with bandwidth and per subscriber control (BSA Broadband Service Aggregator)! High capacity, high availability Service Routers with bandwidth and per service control (BSR Broadband Service Router)! A family of Access Nodes supporting any location, any media, any reach (BSAN Broadband Service Access Node)! Managed home network (via routed home gateway)! Transport-based simple Ethernet aggregation (optional) & long-haul transport Globecom 2006 Date Page 7

Moves it closer to the subscriber in the Service Aggregation Queuing per-service-per-subscriber is essential! Enforce subscriber s access rate for HSI service! Prioritize traffic types and applications! Requires robust queuing structure H-QoS ensures customer isolation on shared second mile Globecom 2006 Date Page 8 BSR IP

13 A New Access Technology for Triple Play Gigabit Passive Optical Networking (GPON) A Quantum Leap in Subscriber Bandwidth! Single fiber supporting bi-directional transmission can be split up to 64 times for up to 64 locations (ONTs)! A combination of broadcast, multicast and dynamic bandwidth allocation can provide 0-2.5Gb/s downstream and Gb/s upstream per user Edge router (data, video) Central Office 1,550 nm to support local CATV Service If required 1,490 nm Typically up to 20 km (28 db) 2.5Gb/s Passive Outside Plant Multi dwelling units Central splitters points Optical Line Terminal 1,310 nm 1.2Gb/s Voice, Data, & Video Softswitch (voice) Single family homes Globecom 2006 Date Page 13

15 A Typical Conclusion: Greenfields Are A Perfect Fit for Passive Optical Networks! Less expensive bit-per-bit than copper! Places a medium in the ground that has nearly unlimited spectrum! Eliminates need for outside plant electronics! Enables dynamic sharing of significantly more spectrum than other technologies (e.g., active Ethernet or cable). Globecom 2006 Date Page 15

16 But A General Answer To PON vs. VDSL Depends On..! Aerial or Buried Plant Rehab? # PON much harder to justify for buried overbuild! How much bandwidth do you need? # 20+ Mbps VDSL solutions are perfect # 50+ Mbps PON is the answer Globecom 2006 Date Page 16

17 Which Brings Us Back To The Question of Video Paradigms! Traditional Cable Paradigm # Broadcast with increasing on demand content delivery and limited bandwidth for third party video providers # VDSL, augmented with a mobile service offering, appears an adequate solution! Bandwidth Free for All Paradigm # Third Party Content Rules # Fiber to the Home will be unmatched! Does a carrier maximize revenue by maximizing bandwidth or by maximizing carrier services (within a fixed bandwidth environment)? # The answer may be key to determining the speed of GPON deployments in North America Globecom 2006 Date Page 17
