6 PSTN CATV TV FIBER LAN INTERNET
TELEPHONY CATV TV FIBER LAN INTERNET Modem DSL Internet,IP-TV Internet, VoIP IPTV, VoIP TRIPLE PLAY MultiService Network Multiservice network all IP based, extending Internet access to Triple Play service Strong competition between different access providers/operators as PTT (DSL), CATV (modem) and greenfielders (fiber, radio). DSL will run into speed problems. PTT starts to support FTTx, Japan installs more fiber than ADSL. Korea next generation access 100 Mb/s FTTx. Verizon invests BUSD in a coming years period Photonics systems roadmap

8 Broadband Subscribers growth Broadband defined as more than ISDN and “ Always On”
Mlines ADSL Cable Fiber Tot Broadband subscribers growth 50%, makes it the fastest growing in telecom sector Traffic volume per subscriber have similar growth, i.e. doubling in total traffic Asia 43% share of broadband lines, America 29% and Europe 28% South Korea leading in penetration, 24,8 lines per 100 people, Sweden 14,4 lines corresponding to more than 30% of the households Fiber has significant contribution in, Italy, Sweden, Japan, South Korea, China The market is maturing. Broadband is not just an oddity in a few unusual countries any more. All the world's major economies - the 'Group of Seven' countries plus China - are now in the top ten as far as the total number of broadband lines is concerned. China is rapidly becoming the world's biggest broadband power. With over 12m broadband lines today, it will overtake Korea in the first quarter of 2004 and Japan within a year or so, and even the USA eventually. Growth in Korea is levelling off. Korea is still the world leader in broadband take-up, with over 25 broadband lines for every 100 people. But the number of new lines added is relatively small now and the main emphasis is on migrating customers to higher-speed services. Broadband prices have been reduced sharply. For example, the major DSL operators cut their prices by 25% on average in the year to September This is an important factor driving take-up. Some broadband value-added services are starting to take off. One leading example is the boom in voice-over-IP services in Japan. Broadband service providers such as Yahoo BB and others are now cutting deeply into NTT's voice revenues with over 5m customers for low-cost telephone service. The cable networks are losing market share of broadband - but only slowly. Telco price cutting, wider coverage and greater financial strength means that DSL is showing bigger precentage increases than cable in most countries. Source: Point Topic, Photonics systems roadmap

13 Metro/Regio-nal Network
Network Trends The future network will be based on IP/ packet aiming at convergence and layer reduction, simplification and flexibility. It is a multiservice network handling best effort traffic, QoS data and legacy services. Still open issues how to do it. Ethernet, due to its low cost ,is migrating into public domain but lacks today carrier class transport properties Next Gen Optical Products can handle both packet and TDM traffic and can interact with legacy equipment and network Intelligence in the optical layer will allow remote network configuration. A common control plane with the IP layer will enable automated switched network ASON/ GMPLS Optical transparency to reduce the need of O-E-O conversions Core Optical Network Metro/Regio-nal Network Broadband Access Photonics systems roadmap

14 Simplified view of the fixed network
Metro Access AN EN Backbone Core XC XC Cross Connect EN Edge Node AN Access Node Residential DSL,Cable Fiber, Radio OED Enter- prise Access Access network: Critical regarding capex as every cost is per subscriber but well defined from user and service perspective. Metro access: Multiarchitecture challenge. Aggregation of all subscriber services with different QoS to multioperators and multiservices core network Transport mainly handled by OED:s, sometimes CWDM is added. Core network: Architectural issues including interoperability in the metro core, where mainly NG-SDH/ SDH and DWDM with (R)OADM are used. Technological challenges in the backbone network with ”fat” pipes of DWDM and higher order SDH. Grooming and switching in OXC. Photonics systems roadmap

15 Two important set of standards to more efficient handle data traffic
IETF OSI layered network MPLS, label switching Circuit oriented packet switching Traffic engineering (protection,..) Traffic separation (VPN tunnelling) Basis for GMPLS 3 I P ( MPLS) 2 Ethernet ATM FR 1 Ethernet SDH Opto 0.5 Lambda ITU-T ITU-T Ethernet Ethernet GFP, Generic Framing Procedure Standard mapping of data into frames OTN, Optical Transport Network New frame structure, parallel with SDH Direct mapping of data on wavelength GFP GFP VC ODU OH OH FEC STM OTN SDH (G 707) OTN ( G709) Photonics systems roadmap

16 Switching and Transparency
GMPLS Dynamic handling of network resources ITU-T has defined an architecture for ASON, Automatic Switched Optical network IETF has extended MPLS to GMPLS( Generalized) and defined a common control for layer 3-1 incl. lambda That way traffic engineering, layer optimization, protection switching can be handled over all layers 2 3 Dynamic handling of optical resources By introducing OXC and ROADM in the network remote control of the optical layer can be achieved and if controlled by GMPLS extended to layer 2 and 3 Optical transparency means dynamic handling in the optical domain . By avoiding unnecessary O-E-O conversions substantial capex can be saved. 50-80% of Internet node traffic is typically pass-through 1 2 3 4 OXC Therefore, the overriding problem for the transport network today is to match the exceptional growth-rate and unpredictability of the data traffic, while simultaneously driving down the cost/bit to the levels required for data networking (which - as discussed – are much lower than in the classic voice networks). The present wave of “classic” build-out using SDH and WDM (and sometimes also ATM) has met the pure capacity, but not in an economical way that enables future “full broadband” services. The challenge for the transport network lies in evolving the classic voice-oriented structure into a transport network that carries data more efficiently, is just as flexible and dynamic as the data traffic, and that also drives down the cost per Mb/s significantly. To this end, major revisions are presently undertaken by all the leading standards organisations to adapt the present transport network standards to a flexible, dynamic, and cost-effective multi-service transport system that will carry both the revenue-bearing traditional voice services (typically 80% of an operator’s revenue) and also enable the economic growth of the new data systems. This effort is known as Next Generation SDH or, more formally the Optical Transport Hierarchy (OTH) The figure illustrates how the traditional voice services (whether POTS, mobile or enterprise) are directly carried on the SDH multiplexing structure (which is what it was designed for), while offloading their data as soon as possible to a dedicated IP-network. However, this IP-network also uses the traditional SDH/WDM network to carry the data. The fast expansion and unpredictable traffic load from the data has put great strains on the underlying transport network. It has been possible to cope with this thanks to the introduction of WDM technology, but the cost of all the IP, (ATM) SDH and WDM systems do not simultaneously drive down the cost/MB to the levels we expected from the Table we just analysed.

OTN standardization and lower transponder cost has opened up Metro applications where WDM also can be used to separate services Two versions, DWDM (Dense) 80 channels and CWDM (Coarse) 8 ch OADM OADM:s are used to create multinode networks, often ring based ROADM (reconfigurable) will be introduced in the future to achieve dynamic network, faster provisioning and automated restoration Photonics systems roadmap

20 OXC, Optical Cross Connect
OOO Three different types of OXC exist, OOO, OEO and combined OOO is an optical or electrical based switch fabrics performing wavelength switching OEO is an electrical switch providing grooming and switching (STM 155) including ethernet mapping OXC as network component is handling the bandwidth management, network and platform consolidation By common control plane remotely controlled a dynamic network is established controlled by OXC. OOO will extend that to wavelength level For smaller applications ROADM, reconfigurable optical add/drop multiplexer, is used instead of OXC Both OOO optical switch fabrics and ROADM are based on immature and expensive technologies but that will improve over the coming years Aggr TRx SDH Eth Wavelength switching SDH 155M switching OEO ROADM Photonics systems roadmap

23 Components and Technology
Modules - Mechanically standardized Tx/Rx modules up to 10 Gb/s direct pluggable - Tunable lasers not yet a mature technology - OEIC in InGaAsP far away commercially but integration is necessary for 100 Gb/s - VCEL lasers interesting due to better yield but still a challenge for 1.3 and 1.55 Passive components - Fibergitter is established today as filter technology for WDM. - Tunable filters for ROADM:s costly today, will improve the coming years - Optical cross connect technologies as MEMS and X-switches have reliability issues - Dispersion compensation is based on fiber today but growing interest for gitter due to smaller dimension Optical Amplifiers EDFA dominating type. Big inventories have reduced development interest but now more focus on metro and access market Raman amplifier has issues with safety etc EDWA potentially a very low cost device but requires substantial development SOA, suffering from performance issues Technology The overall issues with optical technology are size,low integration, lack of memory and processing capability Merits are speed, attenuation and sensitivity Photonic Crystals new area which can offer high Q filters, negative refraction index ! Metallic Optics future potential for integrated optics, even memory chips but long way to go Photonics systems roadmap

24 The Swedish position, Market
The ”IT for all” program 1999 initiated a massive fiber built out and creation of more than 200 public owned city networks From a position as one of the leaders in broadband Sweden has lost some momentum but still high percentage of fiber access Strong competition today between Telia (ADSL), B2, Cable TV operators and the city networks, totally 20 national and 59 regional operators Lowest Internet access prices in Europe and a clear trend to offer triple play but market needs consolidation Most city networks follow the open network concept, growing interest in other countries Broadband Subscriptions in Sweden, Q3 2004 TeliaSonera; 36% B2/Bostream; 26% Glocalnet; 3% Spray (incl Tiscali); 4% UPC; 7% com hem; 12% Tele2; 3% Others; 9% Photonics systems roadmap

25 FTTH in Europe Concentrated in 4 countries (Sweden, Italy, Denmark and the Netherlands) Source: IDATE Photonics systems roadmap

26 The Swedish position, industry Earlier strong position in photonics due to successful collaboration between Ericsson, Telia , universities and institutes. Today much more fragmented picture System vendors Ericsson, Own development in broadband access but sourcing optical transport products. Ericsson strategy for convergence and BB growth? Packet Front, Broadband access systems with provisioning for multiservice as key feature. Very fast growing, founders from B2 and Cisco Transmode (Lumentis), D/CWDM systems, No. 2 worldwide CWDM. Metro WDM applications with built in OXC. Founders from Ericsson Net insight.NG-SDH product based on DTM offering TDM multicasting. Strong in video transport. Founders from Ericsson and KTH Wavium, OXC lambda switch based on electrical core with a powerful management system. Recently restructured, founders from Telia Modules, components Zarlink, strong in VCEL Northligh active in transmitters and EDFA and Proximion focusing on fiber gitter for dispersion compensation the only vendors with some size. Examples on small start ups PhoXtal( diplexer and bistable ROADM switch), InvOpto (low power,small size optical links), Cernolux(T-OADM), Accilon (polari- and spectro meter) and Syntune (tunable lasers). They need marketing support to reach the global market as no ” Ericsson” exists Photonics systems roadmap

27 The Swedish position, Research
The Swedish research in Photonics is mainly concentrated to three organizations, Acreo, KTH and Chalmers High international class in respective special areas but ongoing struggle with financing Acreo, research institute located in Kista, photonics and optical networking, and in Hudiksvall, fiber research. Most of the research in Photonics is done together with KTH in their JV KPRC (Kista Photonics Research Center). Acreo is operating the national test bed located in Hudiksvall (metro access) and in Stockholm (metro core) and a high speed link in between. The test bed with real test pilots is a meeting place for the different actors as vendors, operators, service provider. It is part of three BB EU projects. KTH and KPRC is strong in high speed modulators, laser technology, gratings, packaging and photonic crystals and quantum optics Chalmers has its main focus in high speed modulation, polarization mode dispersion and lasers and work closely with its microtechnology lab. Photonics systems roadmap

28 Summary Due to Internet the traffic volume is growing with almost doubling every year and at the same time price per bit is falling dramatically. To meet this challenge operators are introducing ”next generation IP based network”, handling best effort, QoS data and legacy services. It is supported by next generation photonics systems, optimized for data traffic and offering dynamic, optical transparency and switching The number of broadband subscribers are growing with impressive 50% per year. Triple play i.e. convergence between tele, data and media will increase access speed and support fiber access built Sweden is a mature IT nation willing to explore the broadband society. We have still competence in photonics, both system and research and maybe the rapid growth in the broadband sector and the convergence between fixed and mobile can improve the situation and create a new interest for broadband and photonics. The market has just started! Photonics systems roadmap
