Juniper Networks & Elisa Oyj: World's First 800ZR Service Deployment

In November 2024, Juniper Networks® and Finnish telecom and digital service provider Elisa Oyj, announced they deployed 800Gbps Ethernet services over 800ZR coherent transceivers in an IP-over-DWDM (IPoDWDM) transformation. Using Juniper Networks™ PTX10002-36QDD Series Router and JCO800 coherent optics, the 800ZR enhanced backbone connection allows Elisa to increase the speed and capacity of its optical fiber and mobile networks in support of the AI and cloudification evolution. Elisa's 800ZR deployment is based on Juniper's PTX10002-36QDD using early release versions of Juniper Networks JCO800 coherent pluggable optics; 800Gbps, ZR/ZR+ technology, QSFP-DD form-factor. Designed to support standards-based 100G-ZR, 400ZR/ZR+ and 800ZR/ZR+ transceivers, Juniper's PTX10002-36QDD gives operators the flexibility to selectively deploy either lower cost/reach direct-detect optics, or high-performance coherent optics on a port-by-port basis with no density/power limitations. 
Judge's Comments: “Juniper has developed a flexible platform and deployment that allows Elisa to simplify its aggregation network for its fixed and mobile networks.”
