    Selection Guide for Upgraded Coherent Optical Modules for Distribution Network Automation

    This guide provides a clear overview of 400G ZR QSFP-DD standards, specifications, and selection criteria for coherent pluggable optics in metro and long-haul networks. QSFP-DD ZR Coherent Optics presents a sea of change in the field of optical transportation architecture. The advent of coherent detection revolutionized the dense wavelength division multiplexing (DWDM) market and led to a set of sustaining innovations over the past decade that delivered ever-increasing capacity and lower costs per bit. Compared with standard 400ZR modules that mainly target short DCI. ABSTRACT: The Optical Internetworking Forum (OIF) has been instrumental in standardizing coherent optics at the physical layer, with the 400ZR implementation agreement (IA) being a significant achievement. This white paper reports on the performance evaluation of 400ZR and OpenZR+ pluggable modules. DCO = Digital Coherent Optic 4x100 over CFEC is NOT standardized in OIF.
