  1. Ciena Technology Vision“Enabling Dynamic Ethernet Lightpaths” Jeff Verrant Director, Research and Education Initiatives Jack Oltman Product Line Director – Core Director

  2. Mainframe vs. PC Battle Ciena is pointing to the future of Optical Transport • Traditional design approach : Mainframe: • faster, bigger telecom-specific ASICs • Proprietary, highly integrated optics • Functionality tailored to a specific protocol/task • Ciena is building the first Programmable Optical Layer • Fully programmable blades that can be reprogrammed to any need and application • Pluggable optics from a wide variety of vendors (just like 3rd-part PCI cards) • Taking advantage of datacom FPGA + NPU’s

  3. - X SONET/SDH Ethernet Storage Digital Video OTU Gigabit Ethernet Telecom HW: FPGAs are taking over ASICs • FPGA Technology rapidly approaching the capabilities of ASICs • Allows to build hardware with Software defined functionality • Ciena’s FlexSelect technology is an example where Transponder, muxponder, ring add-drop, sub-wavelength grooming, and cross connect can be SW-configured • Less planning, fewer cards, configurations, and spares • Investment Protection and Future-proofing

  4. $/Performance Time Pluggable optics changes the way we build HW • Everything becomes pluggable & tunable • More suppliers, lower costs, more innovation

  27. FlexLM x 20 SFP with 2 x Port Groups Example: 10 x GigE Plus 4 x OTU1 FlexSelect LM with FlexiPort Technology • Utilize FGPA technology to support FlexSelect architecture • Allow for reload of functionality within a 10G port group – not all functions loaded at all times. For example… • 4 x OTU1, STM-1/4/16 • 8 x STM-1/4, OC-3/12 • 10 x GbE • 4 x CBR2.5G • OTU2, STM-64, OC-192 • 10GbE • CBR10G • For example, one port group on a FlexSelect LM-20 provides 4xOTU1 while the second provides 10xGbE FlexSelect LM-20 FlexSelect LM-2
