Twenty-four vendor companies participated in the initial round of the Optical Internetworking Forum's User Network Interface (UNI), Network-to-Network Interface (NNI) and Physical and Link Layer (PLL) interoperability tests. All vendors that participated were able to successfully demonstrate interoperability. At next week's OFC 2003 conference in Atlanta, the OIF will sponsor a demonstration of the Physical and Link Layer (PLL) Interoperability. The demonstration will highlight the dynamic, end-to-end connection establishment between client devices and optical network elements in the control plane. Specific implementation agreements (IAs) include:
- SPI-4.2: System Packet Interface Level 4, Phase 2: System Interface for Physical and Link Layer Devices
- SFI-4.1: Serdes Framer Interface for a common electrical interface between SONET framer and serial/deserializer parts for OC-192 interfaces
- SFI-5: Serdes Framer Interface Level 5: 40Gbps Interface for Physical Layer Devices
- VSR-4: OC-192 Very Short Reach Interface
- Tunable Laser IA
- TFI-5 work in-progress: TDM switch Fabric to Framer Interface.
