  13. 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 www.isa.se

Backbone Core XC Residential Access Metro Access Metro Core Metro Access EN EN AN AN Residential Access AN AN XC Cross Connect EN Edge Node AN Access Node DSL,Cable Fiber, Radio OED Simplified view of the fixed network 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 www.isa.se

  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 Ethernet SDH 1 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 www.isa.se

  16. GMPLS 1 2 OXC 1 4 3 Switching and Transparency 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 Photonics systems roadmap www.isa.se

  19. WDM system and (R)-OADM WDM • First generation WDM was used for fiber ”multiplication” of SDH • State of art long haul DWDM today is 80+80 (C+L band) channels, each 10 Gb/s i.e 1.6 Tb/s. Repeater distance 400 km, regeneration 6000 km ! • 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 www.isa.se

  20. Wavelength switching TRx TRx Aggr Aggr Aggr Aggr SDH SDH SDH SDH Eth Eth SDH 155M switching 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 OEO ROADM Photonics systems roadmap www.isa.se

  21. Optical Networking Market Photonics systems roadmap www.isa.se

  22. Market Outlook and Trends Revenue Photonics System • Market finally has turned around, 15 % increase in 2004 but still conservative forecast for next 5 years. Compare with 30 BUSD in bubble year 2001! • Next generation products constitute 60% of the market and Metro access network is the fastest growing segment • OED:s 40 % of the market, the majority being NG-SDH • OXC market share dropped to 5 % but will recover and take over DXC:s 10% • ROADM:s will overtake the OADM market share of 20% the coming 5 years • Metro WDM market share around 10%, growing with 15% per year • Long haul DWDM market is about 10 % and quite flat Access systems (data) • Total market 2004was 8 BUSD split between DSL, Cable modem, FTTx and access routers and switches 10 BUSD +10% per year 2004 2010 Photonics systems roadmap www.isa.se

  23. 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 Components and Technology Photonics systems roadmap www.isa.se

  24. Broadband Subscriptions in Sweden, Q3 2004 Others; 9% Tele2; 3% Glocalnet; 3% TeliaSonera; 36% Spray (incl Tiscali); 4% UPC; 7% com hem; 12% B2/Bostream; 26% 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 Photonics systems roadmap www.isa.se

  26. 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 The Swedish position, industryEarlier strong position in photonics due to successful collaboration betweenEricsson, Telia , universities and institutes. Today much more fragmented picture Photonics systems roadmap www.isa.se

  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. KTHandKPRCis strong in high speed modulators, laser technology, gratings, packaging and photonic crystals and quantum optics Chalmershas its main focus in high speed modulation, polarization mode dispersion and lasers and work closely with its microtechnology lab.

  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 www.isa.se
