OIF Pursues DP-QPSK for 100 Gbps Long Haul DWDM

The Optical Internetworking Forum (OIF) has identified Dual-Polarization - Quadrature Phase Shift Keying (DP-QPSK) as a modulation technique for integrated photonic components. With a number of possible modulation techniques available to use at 100G. The OIF said identifying a specific modulation technique gives the industry a starting point to design hardware and reduce development risk.


"We have selected an implementation approach supported by a critical mass of photonic component vendors and users," said David Stauffer of IBM, and the PLL Working Group chair. "100G is an important development for the industry and network element vendors have already begun work. The goal of the project is to accelerate the adoption of 100G in long distance DWDM transmission."


The OIF is pursuing a 100G Long Distance DWDM Transmission Project that will specify an Implementation Agreement (IA) for Integrated Receive and Transmit photonic component(s) for Dual-Polarization - Quadrature Phase Shift Keying (DP-QPSK). The IAs will define partitioning of photonics sub-components, the electrical and the optical interface. The objective of these IAs is to create a foundation for Multi-Source Agreements for transmit and receive photonic components.


In other news from its Q3 meeting in Montreal, the OIF has developed and published a guideline document for Signaling Protocol Interworking of ASON/GMPLS Network Domains. The Guideline Document is available onilne.http://www.oiforum.comhttp://www.oiforum.com/public/documents/OIF-G-Sig-IW-01.0.pdf
