  1. Advancing Optics with Physical & Link Layer Interoperability Steve Joiner OIF Technical Committee Chair Ignis Optics steve.joiner@ignisoptics.com

  2. Agenda • Mission of the Optical Internetworking Forum • OIF’s Strategy to advance optics • What are Implementation Agreements? • Published Implementation Agreements • Work in Progress • OIF at Supercomm2003

  3. OIF’s Mission • Foster the development and deployment of interoperable products and services for data switching and routing using optical networking technologies. • Requires addressing multiple issues related to optical internetworking for • Carrier • System vendor • Component vendor Integrated approach strengthens the OIF’s ability to fulfill its mission.

  4. Strategy to Achieve Mission • Industry Driven Focus • Carrier Voice in the technical committee • Membership driven • Develop Implementation Agreements • Rapid Development controlled by a rigorous standards-like process • Working Group Organization • Carrier • Architecture • Signaling • OAM&P (security) • Physical and Link Layer (PLL) • Interoperability

  5. Implementation Agreements • Narrowing the choices to a single profile • Create the “Glue Logic” that enables the commercial implementation of standards • Create new standards when needed

  6. Do IAs advance the optics industry? • Improves development efficiency • Collective wisdom prevails • Reduces development mis-steps • Results driven process required • Technology providers make first solution selection • Improves adoption rate by industry • Interoperability tests reduce risk • Improves confidence in new technology • Improves system cost • Creates competition • Competitive edge driven by factors other than basic performance; i.e. price, efficiency, etc. • Improves time to market

  7. Published IAs • Network control and signaling • Electrical interfaces • Optical interfaces • Optical multi-source agreement • Security • Critical non-IAs driving the industry • Carrier Requirement Documents • Liaisons to ITU, IETF, T1X1…

  8. OIF Electrical Specifications

  9. OIF Electrical Specifications • SFI = SERDES to Framer Interface • SPI = System Packet Interface • TFI = TDM Fabric Interface • CEI = Common Electrical Specification Electrical Interface Architecture for the Data Path
