Courcoubetis, G.D. Stamoulis Broadband 4: Cable, fiber, - 11

12 Source: Data-rate vs. Users Trade-off in Cable C. Courcoubetis, G.D. Stamoulis Broadband 4: Cable, fiber, - 12

13 Broadband over Powerline (BPL) (I) Power distribution network used for delivering broadband services Other names: Powerline Communications (PLC) Powerline and power grid are already here! No more wires Very large base of potential customers Point-to-multi point Total rates up to 200Mbps (upstream & downstream) shared by all users Actual rates depend on topology and other equipment connected Symmetric and asymmetric rates can be offered C. Courcoubetis, G.D. Stamoulis Broadband 4: Cable, fiber, - 13

14 Broadband over Powerline (BPL) (II) Sharing of rates Typical rate 45 Mbps USA: typically 50 houses per substation ~1 Mbps per customer Europe: can be 200 houses per substation can drop to ~250 kbps per customer Access loop length may affect rates Can be avoided with power adjustment Major issue: Interference, e.g. with commercial HF radios Also raises security issues Still low commercial penetration Standards still evolving C. Courcoubetis, G.D. Stamoulis Broadband 4: Cable, fiber, - 14

15 Broadband in Gas (BiG) Gas pipes can server as wave-guides Wireless technology, but electromagnetic RF waves are not in the air BiG can offer up to 100 Mbps to distances ~10 km Similar cost as DSL Theoretically, distance can reach 100km Applicability limited only where gas network is present Gas, water and sewage networks can also be used for laying fiber inside their pipes in a cost effective way Rather than digging ducts in trenches in the streets C. Courcoubetis, G.D. Stamoulis Broadband 4: Cable, fiber, - 15

16 Fiber Access and Metro Ethernet C. Courcoubetis, G.D. Stamoulis Broadband 4: Cable, fiber, - 16

17 Fiber networks Fiber is the most appropriate medium for backbone networks It can also be used in different parts of the access network Fiber supports large access rates symmetric or asymmetric from ~1 Mbps to ~1 Gbps Certain applications are already very demanding: HDTV, peer-to-peer sharing of large files C. Courcoubetis, G.D. Stamoulis Broadband 4: Cable, fiber, - 17

18 Source: Planning Applications & Rates vs. Broadband Access Technologies C. Courcoubetis, G.D. Stamoulis Broadband 4: Cable, fiber, - 18

22 FTTH/B coverage: up to Source: OECD C. Courcoubetis, G.D. Stamoulis Broadband 4: Cable, fiber, - 22

23 From the CO to the ONU Point-to-point fiber One pair of optical fiber from CO (Central Office) to each ONU (Optical Network Unit) ONU SDH rings ONU CO ONU CO cable ONU ONU ONU ONU ONU No sharing of optical fiber, optical CO technologies No power splitting, no synchronization of nodes C. Courcoubetis, G.D. Stamoulis Broadband 4: Cable, fiber, - 23

24 Passive Optical Network (PON) Allows for better exploitation of fiber capacity Reduces the cost of FTTH // // // // // // Optical Line Terminal - OLT // Passive Optical Splitter // // Optical Network Unit - ONU // C. Courcoubetis, G.D. Stamoulis Broadband 4: Cable, fiber, - 24

26 Business Roles and Value Chain 1. Infrastructure Provider: owns and manages passive fiber infrastructure 2. Telecom provider: owns active devices (including Optical Line Terminal) and offers wholesale fiber access to ISPs 3. ISP: provides retail broadband Internet service to customers 4. Customer C. Courcoubetis, G.D. Stamoulis Broadband 4: Cable, fiber, - 26

27 Architecture and Business Roles Infrastructure provider wholesale provider Source: A.T.Kearney/Planning C. Courcoubetis, G.D. Stamoulis Broadband 4: Cable, fiber, - 27

28 Remarks on fiber networks FTTHome involves a dedicated fiber per customer, bringing ~1Gbps Very expensive FTTBuilding, FTTCurb and PON FTTH Are less expensive Fit present needs of customers FTTB and FTTC are often combined with VDSL C. Courcoubetis, G.D. Stamoulis Broadband 4: Cable, fiber, - 28

29 Impact of fiber networks to OTE Fiber networks compete with broadband leased lines in both retail and wholesale markets mainly in urban areas Combined with Internet access and VoIP, they compete with fixed telephony Can also compete with wholesale bitstream services of similar rate OTE can serve as infrastructure provider and/or wholesale provider C. Courcoubetis, G.D. Stamoulis Broadband 4: Cable, fiber, - 29

30 Metro Ethernet (I) Carrier technology deployed by service providers in core metropolitan networks to supply various services. ME is Used for: retail services, e.g. leased lines (for interconnecting LANs etc.) wholesale services (interconnecting provider s POPs) higher-level services (i.e. VoIP) ME is based on the transmission of Ethernet frames on a Metropolitan Area Network (MAN) Provides Ethernet Virtual Connections with capability for: point-to-point E-line, which can also offer Internet access multipoint-to-multipoint E-LAN, for LAN services and VPNs Different service classes C. Courcoubetis, G.D. Stamoulis Broadband 4: Cable, fiber, - 30

31 Metro Ethernet (II) Point-to-Point EVC UNI CE CE MEN UNI E-Line Service type Multipoint-to-Multipoint EVC UNI UNI CE CE MEN CE UNI UNI CE E-LAN Service type C. Courcoubetis, G.D. Stamoulis Broadband 4: Cable, fiber, - 31

32 Metro Ethernet (II) Cost-effective solution with large customer base Allows flexible bandwidth profiles as a retail service Ranging from 1 Mbps to 1Gbps, with small step Supports: Committed + Excess rates E-Lines and E-LANs can be used to carry VoIP Impact to OTE: Similar with fiber networks C. Courcoubetis, G.D. Stamoulis Broadband 4: Cable, fiber, - 32

33 Concluding Remarks C. Courcoubetis, G.D. Stamoulis Broadband 4: Cable, fiber, - 33

34 Certain Combinations of Access and Backhaul Solutions C. Courcoubetis, G.D. Stamoulis Broadband 4: Cable, fiber, - 34

35 Cost Comparison of Certain Combinations C. Courcoubetis, G.D. Stamoulis Broadband 4: Cable, fiber, - 35

36 And the winner is DSL has significantly higher penetration so far, particularly for home customers in urban areas Still the best combination of bit-rate, service quality, cost Benefits from continuous upgrades Fiber To The Home delayed in most countries Except the top ones: Japan, Korea etc. Strategic efforts to boost its penetration in several countries, including Greece Business customers demand for the various solutions is more balanced Wireless is more successful in this segment C. Courcoubetis, G.D. Stamoulis Broadband 4: Cable, fiber, - 36

37 The future picture Wireless technologies progress very fast Cellular moves towards broadband Fixed wireless moves towards mobility 3G+ (LTE) and WiMax are expected to be the winning combination for mobile broadband Higher bitrates are coming up for all technologies, but this requires: more fiber upgrading of backhaul more spectrum, for wireless technologies Penetration of new technologies will also depend on prices C.
