Product Description
Juniper Networks® JCO400-ZR and JCO400-ZR+ 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-ZR/ZR+ coherent DWDM optics deliver industry-leading performance and operational simplicity while supporting an open and interoperable networking ecosystem. The lower TCO makes them a compelling value for service providers and cloud providers.
The portfolio includes two offerings:
- JCO400-ZR
- JCO400-ZR+
This datasheet provides the preliminary specifications of the JCO400-ZR. Specifications for JCO400-ZR+ will be added to the datasheet in the near future.
JCO400-ZR
JCO400-ZR coherent DWDM optics comes in a universal quad small form-factor double density (QSFP-DD) footprint that can be plugged into any Juniper 400GbE-platforms. JCO400-ZR conforms to the Optical Internetworking Forum (OIF) 400ZR Implementation Agreement (IA) and is well suited for IP-optical integration eliminating coherent DWDM transponders, increasing reliability, lowering cost, reducing power, and minimizing footprint.
JCO400-ZR+
JCO400-ZR+ coherent DWDM optics comes in a universal QSFP-DD form factor that can be plugged into any Juniper 400GbE-ready platforms. In addition the JCO400-ZR+ module supports flexible configurations and channelized modes as specified in the OpenZR+ Multi-Source Agreement (MSA). These transceivers employ Open Forward Error Correction (OFEC), which increases data reliability and maximizes overall effective bandwidth. Open and interoperable, the JCO400-ZR+ coherent DWDM pluggable module delivers best-in-class power efficiency and extended reach for metro, regional, and long-haul applications.
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.
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.
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.
