Physical and Link Layer

40 Gbps Optical Modulation Techniques
The scope of this project includes investigation into non-NRZ modulation techniques, including but not limited to: DuoBinary and DQPSK. Items to be considered in the investigation include dispersion tolerance, fiber non-linearities, optical filters such as OADMs. The expected output of this project is the study on different modulation schemes and a recommendation in the form of a white paper.

Implementation Agreement for 100G Long-Distance DWDM Transmission
The OIF’s Physical and Link Layer Working Group (PLL WG) recently designated a new work project to address 100G long-haul DWDM. The 100G long-haul project will result in a DWDM transmission implementation agreement (IA) focused on a specific modulation format and receiver approach. It will seek to reach agreement on a Forward Error Correction (FEC) algorithm suitable for the long-haul 100G application. This IA will complement and build upon the work already underway defining 100G Ethernet in the IEEE, and the new 100G level of the Optical Transport Hierarchy (OTH) in the ITU-T. For more information on this project, contact Karl Gass at kgass@sandia.gov

100G Long-Distance DWDM Transmission Integrated Photonics Components
The OIF’s Physical and Link Layer Working Group (PLL WG) is working on a project that will specify Implementation Agreements for integrated photonic components in support of 100G long-distance DWDM transmission. The objective of this specification is to create a foundation for MSAs for transmit and receive photonic components. For more information on this project, contact Karl Gass at kgass@sandia.gov

Common Electrical Interface - 25Gb (CEI-25)
This project defines an electrical layer interface with a signaling rate of 20 to 25 Gbps for next generation systems. This project is the next evolutionary step beyond the existing Common Electrical Interface (CEI) IA, which defines electrical layers for signaling rates up to 11.1 Gbps. CEI-25 electrical layer will form the basis of future protocol interfaces developed by the OIF. One goal of the project is to provide important input to the IEEE 802.3 HSSG effort in a manner similar to how CEI-11G served as an important input to the IEEE 802.3ap effort. For more information contact Dave Stauffer, PLL Working Group Chair at dstauffe@us.ibm.com

Electronic Dispersion Compensation (EDC) Modeling
The EDC Modeling work is an effort to measure both transmitters and EDC enabled receivers and to develop the model necessary to fulfill this project goal. The results of this work will be presented in the form of white papeprs, primarily for submission to other standards bodies. For more information contact Karl Gass at kgass@sandia.gov

Scalable SERDES Framer Interface (SFI-S)
The OIF has launched a SERDES Framer Interface SFI-X project that will define a scalable interface from an optical module to a framer device for line rates from 40 Gbps to 100 Gbps and beyond. The SFI-S project forms an important contribution to the requirements for transport of high-speed data via the OIF’s Common Electrical Interface (CEI). The current, ongoing CEI-25 project establishes electrical signaling rates for high-speed backplanes. The next generation SFI-S will support the aggregation and deskewing of 4-16 data lanes at CEI (6 - 11G) or future CEI-25 (20 - 25G) signal rates. The SFI-S project is an extension of the prevalent OIF SFI-4 specification for 10 Gbps interfaces. SFI-S is targeted to support the 100G work being addressed by standards bodies like IEEE 802.3 HSSG and ITU-T, and forums like ATIS and the Ethernet Alliance.

Integrable Tunable Transmitter Assembly - MSA
The Integrable Tunable Transmitter Assembly (ITTA) is a tunable laser integrated with a modulator surrounded by electronics board containing the necessary laser and modulator control electronics. The ITTA has the same form factor as the Integrable Tunable Laser Assembly (ITLA) and shares the same communication protocol. The ITLA interface has been extended to allow software control of the modulator and to specify the high speed data interface. The ITTA contains the RF driver function to allow different modulator technologies to be multi-sourced. The ITTA is designed to be used in 300 pin large form factor and small form factor transponders, as well as discrete line card applications.

Networking

E-NNI 2.0 Routing
The E-NNI 2.0 Routing project addresses additional routing support for multilayer UNI and E-NNI signaling. For more information on this project contact Jonathan Sadler, Architecture & Signaling Working Group Chair at jonathan.sadler@tellabs.com

E-NNI 2.0 Signaling
The E-NNI 2.0 Signaling IA defines the protocol used across the E-NNI reference point between adjacent domains (either within the same carrier network or in two different carrier networks) for the purpose of establishing optical connections. E-NNI signaling functions, along with the OIF UNI 2.0 and I-NNI signaling protocols (the latter not specified by OIF), are used to establish end-to-end connection services over multiple domains. The E-NNI 2.0 Signaling IA adds a number of features not found in the E-NNI 1.0 Signaling IA, including: - the protocol elements necessary to provide UNI 2.0 services - clarification of how the different E-NNI identifiers are used in the signaling protocol. For more information, contact Jonathan Sadler, Architecture & Signaling Working Group Chair at jonathan.sadler@tellabs.com

Control Plane Security
The OAM&P Working Group is working on an Implementation Agreement on Security Extension for UNI and NNI version 2.0. This combines the original Security Extension and its Addendum into a single document and brings the methods up to date with current work in the OIF and IETF. For more information on this project contact Doug Zuckerman, OAM&P Working Group Chair at w2xd@aol.com

Multilayer Signaling
The Architecture and Signaling Working Group is working on an amendment to the OIF ENNI 2.0 Signaling Implementation Agreement that covers multi-layer signaling. The amendment is additive to the OIF ENNI 2.0 Signaling IA. The document will provide updated requirements for signaling in support of the ENNI Intracarrier Signaling interface and define methods to meet these requirements as well as prototype encodings to be used in OIF Interoperability testing.
