The Optical Internetworking Forum (OIF) Physical and Link Layer Working Group (PLL WG) designated a work project to address 100 Gbps (100G) long-haul dense wavelength division multiplexing (DWDM).
This project is designed to foster the development of an ecosystem where service providers, data and optical networking equipment vendors, optical module and subsystem vendors and underlying component providers will work together to accelerate the availability of transmission solutions for 100G, according to the OIF.
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, said the OIF.
This IA will complement and build upon the work already underway defining 100G Ethernet in the Institute of Electrical and Electronics Engineers (IEEE) and the new 100G level of the Optical Transport Hierarchy (OTH) in the International Telecommunication Union Standardization Sector (ITU-T), said the OIF.
Additionally, members of the PLL WG adopted baseline requirements for an electrical specification for 25 Gbps backplane (long reach) interfaces.
This follows the prior adoption by the WG of baseline requirements for an electrical specification for 28 Gbps chip-to-chip and chip-to-module (short reach) interfaces.
These electrical specifications will be added as additional clauses in the next generation of the Common Electrical I/O (CEI) IA.
