FTTP

2. 2 Strategic Product Focus

3. 3 RFoG Vs. IPTV Why Not IPTV? Standards are not fully developed Headend equipment is expensive and subject to change as the standards evolve New MPEG 4 set top boxes needed in the Customer�s premise �Back office� support does not yet exist at the cableco Workforce has little if any experience in the IP domain Why RFoG? Uses the headend technology already in place Uses the set top boxes already in place Uses the DOCSIS platforms already in place and supports DOCSIS 3 Simply replaces what would be the traditional RF node No �back office� changes are needed. �Business as usual� Little workforce training is needed

4. 4 Return can be transmitted at 1310 or 1610* nm 1310 nm is a lower cost solution today 1610 nm is the GPON friendly solution Compatible with PON standards PON standards support 1490 nm downstream, 1310 nm upstream RFoG Spectrum

5. 5 RFoG Reference Design

6. 6 Evolutionary FTTx

7. 7 RFoG Node Configuration 24 dBm output EDFA (21 dBm x2) Integrated downstream split / upstream 1310 (or 1610) filter Dual Quad channel analog return Rx Digital upstream to the headend Can be up to 80 KM HE to Home Can mux up to 15 CWDM RFoG nodes on a single fiber or 40 DWDM

8. 8 Micro-node Specs

9. 9 Simple RFoG Design

10. 10 Hybrid BC/NC RFoG Design

11. 11 RFoG Fiber Management

12. 12 RFoG Capital Expense

13. 13 RFoG Capital Expense

14. 14 RFoG Limitations Downstream reach traditionally limited by EDFA output, splitter loss, CPE input requirements Upstream reach limited by CPE laser, splitter loss, receiver input requirements, and channel loading Upstream laser typically a low-cost, low-power unit Fiber count �Just cable TV� services What happens next when MSOs need to provide even higher bandwidth services?

15. 15 What is RFPON? RFPON: Next-generation RFoG RFoG with the ability to seamlessly add GEPON capabilities Simple, cost-effective way for MSOs to deploy FTTP Same services as traditional HFC Same technology as traditional HFC Same back-office provisioning systems as DOCSIS system Ideal for: New housing developments where FTTP is a must Low density, rural areas of the franchise Can serve homes, businesses and MDUs SCTE standards initiative in process

16. 16 RFPON

17. 17 Evolutionary FTTPDOCSIS� & GEPON RFPON VHub� providing video, DOCSIS data and voice services PLUS capacity for 2 PON modules GEPON compliant 1490 nm downstream, 1310 nm upstream Up to 256 Video+DOCSIS customers PLUS up to 128 (2x64) GEPON customers Each GEPON module supports 1 Gbps bandwidth Up to 64 customers DOCSIS back-office provisioning One system for both solutions No operator re-training

18. 18 Simple RFPON Design

19. 19 GEPON Module Compatible with HFC or Fiber Deep architectures Serves up to 64 customers using standard PON CPE devices Bandwidth rate limiting from 1 Mbps to 1000 Mbps in 1Mbps steps Compatible with standard GigE switch at head-end Compatible with Aurora digital return and NI3030E

20. 20 Cost Comparison (Today)

21. 21 Cost Comparison (Future?)

22. 22 CPE Cost Comparison

23. 23 In Summary RFoG�s cost is more than HFC in high take rate / high density locations Can be lower CapEx in low take rate / low density applications Does not require specialized technicians Does not require �back office� changes RFPON is the next-generation RFoG Extends reach / Reduces cost / Reduces fiber count Doubles upstream bandwidth (compared to DOCSIS 3.0) Seamless evolution to include PON functionality Standards-based GEPON Up to 64 users per GEPON module Integrated with deployed DOCSIS provisioning system
