OIF releases new 1600ZR specification for 1.6T coherent line interface

By Optical Connections News Team

The Optical Internetworking Forum (OIF) has announced the publication of its Implementation Agreement (IA) for 1600ZR Coherent Interfaces. This specification defines an interoperable 1.6T coherent line interface and frame format for single-span, amplified, point-to-point Dense Wavelength Division Multiplexing (DWDM) links up to 120 kilometres. The highly anticipated IA doubles the capacity of OIF’s 800ZR specification, […]
