The Optical Internetworking Forum (OIF) has launched a new effort around forward error correction (FEC) for 100G networks. The work marks the group’s second major 100G push; the first of which addressed 100G Long Distance DWDM Integrated Photonic Components.
The FEC project addresses the propagation challenges facing the optical networking industry in the long-distance application for OTU4 transport. The OIF’s goal for the project is to develop a common error correction code that can be implemented cost-effectively in the near term while helping to meet the demanding propagation targets for 100G long-haul transmission in an interoperable way.
The Forward Error Correction for 100G DP-QPSK Long Distance Communication IA will study and seek to reach agreement on an FEC algorithm suitable for long-haul 100G applications. Defining a common basis for a FEC encoder, interleaving and overhead rate will add to the scope of the 100G Long Distance DWDM Transmission Framework IA, creating common building blocks for the long haul communication space. The agreement will complement and support the work already underway defining 100G Ethernet in the IEEE, and the OTU4 of the Optical Transport Hierarchy (OTH) in the ITU-T.
