OIF Approves 100G Coherent Receiver

The Optical Internetworking Forum (OIF) has approved an implementation agreement (IA) for the 100G Integrated Polarization Intradyne Coherent Receiver.


The implementation agreement specifies key aspects of integrated receivers for coherent DWDM applications. The IA supports DP-QPSK modulation as specified in the OIF's 100G Framework Document and also specifies operating rates up to 32GBd.


The OIF said its implementation agreement strives to remain modulation format and data rate agnostic to maximize applicability to potential future applications.


"Many vendors are currently developing coherent receivers based on the OIF's 100G receiver IA and their availability is already having a significant impact on the design of next generation of DWDM hardware," said Jeff Hutchins, CoreOptics and OIF Board member.


In addition, the OIF has completed a Forward Error Correction (FEC) whitepaper summarizes its investigation of FEC for use with 100G DP-QPSK transmission in long distance DWDM communications. The paper examines the propagation challenges and suggests an upper bound for spectral coding overhead for the OIF's integrated photonics projects. The whitepaper complements and supports the work already underway defining 100G Ethernet in the IEEE and the OTU4 of the Optical Transport Hierarchy (OTH) in the ITU-T.
