OpenZR+ Whitepaper, "Multi-Vendor 400G Coherent Optical Transceiver Interoperability Testing," December 2023

A core principle of OpenZR+ is to foster multi-vendor interoperability to cultivate healthy competition in the industry. This not only bolsters network reliability and resilience, but also facilitates the creation of a more versatile and adaptive network infrastructure. Additionally, OpenZR+ is dedicated to specify solutions that operate in real-world scenarios. To validate the efficacy of the 400G OpenZR+ solution, the OpenZR+ MSA group conducted Phase 1 and Phase 2 test events at LightRiver. The test results were successful in showing compatibility to the OpenZR+ specification and interoperability between optical transceiver modules from different vendors in two different routers by transporting 400 Gb/s traffic over various optical links.

OpenZR+ Whitepaper: "OpenZR+: 400G Digital Coherent Optics for Multi-Haul"

OpenZR+ MSA provides a digital coherent optic transceiver that can be plugged into a range of routing, switching, or optical transport host platforms. With 400G, 300G, 200G, and 100G modes, long-haul applications can also be addressed. The 4x 00GE multiplexing mode allows for the connecting of 400GE- and 100GE-capable devices across a DWDM link.
