  1. ISL Verbindungen und WDM Matthias Kayser Director Business Development matthias@smartoptics.com Fibre Channel Symposium 2012, Wien

  2. SmartOptics Company Overview • SmartOptics Company Facts • Founded in 2005 • Headquarter in Oslo, Norway • Development in Stockholm, Sweden • Part of the Finisar Group since 2011 • Provides complete portfolio of: • Data Center Connectivity • Passive WDM Networking (Mux/Demux/OADMs) • Optical Transceivers • Active WDM Networking (EDFAs, transponders) • Semi-Passive DWDM Networking • since 2006

  3. ISL Trunking and (embedded) WDM

  4. Conventional Transmission One service per fiber pair FC #1 FC #1 FC #2 FC #2 FC #3 FC #3 FC #4 FC #4 FC #5 FC #5 FC #6 FC #6 FC #7 FC #7 FC #8 FC #8 Important when using ISL: “Trunks operate best when the cable length of each trunked link is roughly equal to the others in the trunk. For optimal performance, no more than 30 meters difference is recommended. “* * FabricOS Administrator'sGuide, FabricOS 7.0.1, Brocade 53-1002446-01

  5. WDM Transmission Multiple services per fiber (pair) FC #1 FC #1 FC #2 FC #2 FC #3 FC #3 FC #4 FC #4 FC #5 FC #5 FC #6 FC #6 FC #7 FC #7 FC #8 FC #8 • Each wavelength creates a ”virtual fibre” • WAN fibre requirements reduced by the factor of used wavelengths • Pay-as-you-grow, new wavelengths can be added without traffic interruption • Multiple protocols/speeds can operate over different wavelengths on the same fibre • All services are operating over exactly the same fiber distance!

  6. Typical dual fiber and single fiber transmission using WDM • Dual fiber solution • Single fiber solution 1 fiber pair 1 single fiber Example: 8ch. CWDM module

  7. Embedded WDM (no transponders) C/DWDM SFP in client equipment WDM Mux/Demux Colour coded LC Patch cord to Mux/Demux

  8. Embedded WDM – So how does it work? Up to 80 FC / IP connections, Up to 100km, no power required • Use colored C/DWDM SFP/SFP+/XFP directly in SAN/LAN equipment • Use C/DWDM Mux/Demux units to combine/split wavelength channels • LC-LC Patch cord from transceiver to multiplexer • Wavelengths are like virtual fiber pairs • no additional latency, ISL Trunking possible • no special SAN equipment configurations • passive solution, thus best reliability typ. 450 years MTBF • Ethernet and Fibre Channel/FICON can be used on the same system

  9. Why embedded WDM in the Datacenter ? • In general: • No need for active WDM equipment for simple poin-to-point networks • No management overhead • Lower cost (both CAPEX and OPEX) • Less space • No power consumption • No extra points of failure • For ISL Trunking: • Active equipment adds extra Latency • Muxponder Solutions do mostly NOT support trunking

  10. But: Optical transceivers have issue with higher data-rates -> Amplified solutions are needed for higher datarates and longer distances!

  11. Market for Passive vs. Active WDM Solutions so far Passive WDM Networking Active WDM Networking 0 to 70 km 70 to 2000 km

  12. Now the Rules are changing  Semi Active WDM Networking Active WDM Networking Passive WDM Networking 0 to 70 km 200 to 2000 km 70 to 200 km

  13. DWDM Data Center Interconnect (DCI)for distances >40 km

  14. m:series: Plug & Play DWDM Distance Extension • Minimum Complexity • Minimum Cost • Maximum Speed • Maximum Distance • Industries first semi-passive WDM platform • Intelligent „all in one“ Mux/EDFA/DCF/NMB platform • Cost & technicalbenefitsofembedded WDM system • Distanceperformanceofactive WDM platform • 4+4 / 16+16 channelsolutions (today) • Upto 200km transmissiondistancefor 10G • All protocolsupto100G supported • Removesdependency on active DWDM system • Nocomplicatedplanning, setuporconfiguration • Simple Plug & Play

  15. Embedded WDM (no transponders) DWDM SFP in client equipment WDM Mux Colour coded LC Patch cord to Mux/Demux

  16. Traditional DWDM approach (using transponders) All separate blades in DWDM system 850nm SFP i/p in to transponder 850nm SFP in client equipment Transponder WDM Mux EDFA Booster EDFA Preamp Dispersion Comp. OSC Add/Drop OSA NMB DWDM SFP o/p from transponder Mux/Demux combines all signals on to single output

  17. Traditional DWDM approach (using transponders) All separate blades in DWDM system 850nm SFP i/p in to transponder 850nm SFP in client equipment Transponder WDM Mux EDFA Booster EDFA Preamp Dispersion Comp. OSC Add/Drop OSA NMB DWDM SFP o/p from transponder Mux/Demux combines all signals on to single output

  18. Semi Active WDM Networking using m:series DWDM transceiver still plugged directly into SAN equipment Patch cord still connects traffic to the “Mux/Demux” But the“Mux /Demux”is intelligent  m:series Automatic Power Equalization and Link Adjustment Network Management Optical Monitoring Dispersion compensation Optical Amplification

  19. Embedded DWDM and Semi Active distance extension Up to 32 FC / IP channels, up to 200km, Exactly the same concept as Passive WDM !

  20. Wichtige Parameter für das Design von WDM Links Optische Parameter: Länge der Dark Fiber Optische Dämpfung der Dark Fiber Typ der Glasfaser (z.B. G.652 oder G.655) Zu übertragende Services: Anzahl benötigter Services am Tag 1 und für die Zukunft Geschwindigkeit der geplanten Services am Tag 1 und für die Zukunft FC Switch: Lizenz für ISL Lizenz für BufferCredits Details siehe auch im Brocade „FabricOS Administrator'sGuide“

  22. Summary • Active Embedded DWDM Networking • Embedded Networking still growing in importance • IPoDWDM • Even better fit for higehr data-rates as transponder cost is of higher importance • Sweet spot is still <120-160 km • Data Center Connectivity • Regional IP Networks
