Interoperability paves the way for the development of OpenZR+ modules in a QSFP-DD or OSFP form factor that support performance and functionality beyond 400ZR
MAYNARD, Mass. and YOKOHAMA, Japan, Sept. 23, 2019 (GLOBE NEWSWIRE) -- Acacia Communications, Inc. (ACIA), a leading provider of high-speed coherent optical interconnect products, and NTT Electronics, Co. (NEL), a leading supplier of coherent Digital Signal Processor (DSP) solutions to system and module manufacturers worldwide, today announced that they have completed testing to demonstrate interoperability between OpenZR+ coherent DSPs by exchanging test vectors. The OpenZR+ mode leverages elements from both 400ZR and OpenROADM industry standardization efforts, both of which appear to be gaining industry momentum. The OpenZR+ implementation was designed to enable enhanced functionality and improved performance in pluggable form factors, such as QSFP-DD and OSFP, in order to support multi-vendor interoperability. The 400ZR effort driven by the Optical Internetworking Forum (OIF), is focused on data center interconnects (DCIs), while the OpenROADM effort is focused on carrier applications. Acacia and NEL will be sharing interoperability results between their OpenZR+ enabled DSPs at the 45th European Conference on Optical Communication (ECOC) on September 22-26 in Dublin, Ireland.
“We believe that the availability of merchant DSP solutions supporting OpenZR+ will be a significant milestone by helping to expand the use cases for interoperable coherent pluggable modules in a QSFP-DD or OSFP form factor,” said Tom Williams, Vice President of Marketing at Acacia Communications. “OpenZR+ was designed to combine the focus on ethernet traffic of 400ZR, the performance of the OpenROADM specification, and multi-vendor interoperability in order to provide network operators with an operationally efficient solution for DCI applications with reaches beyond 120km.”
“The enhanced functionality and improved performance of OpenZR+ was designed to allow network operators to address a wide range of applications using this interoperable solution,” said Atul Srivastava, CTO at NTT Electronics America. “By exchanging test vectors with Acacia, we are helping to enable network operators to move forward with increased confidence that multiple module vendors will be supporting the OpenZR+ ecosystem.”
The OpenZR+ mode maintains the simpler ethernet-only host interface of 400ZR, but adds support for multi-rate Ethernet and multiplexing capabilities at 100G, 200G, 300G or 400G line interfaces with higher dispersion tolerance and higher coding gain using openFEC selected for standardization by the OpenROADM MSA and CableLabs.
