Product Description
Juniper Networks® JCO400-QDD-ZR and JCO400-QDD-ZR-M Coherent Optical Transceivers are supported by 400GbE-ready router and switch platforms within the Juniper Networks ACX Series Routers, MX Series Routers, PTX Series Routers, and QFX Series Switches. Ideal for access, edge, core, data center, and cloud use cases, JCO400 coherent DWDM optics deliver industry-leading performance and operational simplicity in a footprint-optimized form factor while enabling service providers and cloud providers to realize the TCO savings of a converged IP-Optical architecture.Â
JCO400-QDD-ZR conforms to the Optical Internetworking Forum (OIF) 400ZR Implementation Agreement (IA), which was defined to address the growing demand from cloud providers for massive interconnect bandwidth between distributed data centers. Making use of Concatenated Forward Error Correction (CFEC), 400ZR transceivers can facilitate extended reach interconnects at scale with optimized power consumption.
JCO400-QDD-ZR-M conforms to the OpenZR+ Multi-Source Agreement (MSA), which extends upon the OIF 400ZR specification to address multiple performance-demanding applications required by CSPs for metro, regional, and core use cases. OpenZR+ transceivers employ Open Forward Error Correction (OFEC), which improves the net coding gain and maximizes the achievable performance at longer distances. As defined by OpenZR+ MSA, JCO400-QDD-ZR-M supports flexible configurations in various channelization modes to enable multiple use cases to be serviced out of a common module.

Features and Benefits
Industry-Leading Performance
The JCO400-ZR/ZR+ optics solutions provide best-in-class power efficiency in a footprint-optimized form factor that suits a range of metro, edge, and core network use cases, including data center interconnect, mobile backhaul, next gen packet core networks, and more. JCO400-ZR/ZR+ modules support flexible configurations and channelized modes as specified by the OIF 400ZR IA and OpenZR+ MSA.
Â
Operational Simplicity
JCO400-ZR/ZR+ optic modules help network operators alleviate operational pain points in managing the health of the end-to-end IP/optical solution. For example, the JCO400-ZR/ZR+ optics have the ability to separate the operation of the host and line side interfaces. Separating the operation of the two interfaces enables simplified testing and provisioning of the optical elements of the network, independent of the IP-Ethernet layer. Additionally, Juniper supports the use of standardized OpenConfig models for vendor-agnostic management of 400GbE Coherent DWDM Optics, providing ease of integration, deployment, and network maintenance.
Â
Open and Interoperable
As an active contributing member of the OIF, OpenZR+ MSA, and QSFP-DD MSA among other key optical-standards bodies, Juniper is at the forefront of building open and interoperable networking ecosystems. Juniper leverages a standards-compliant, multivendor ecosystem to seamlessly diversify the component supply chain ensuring stable supply and improved lead times.
