Juniper Networks QFX10002-36Q-DC is a high-performance, fixed-configuration data center switch engineered by Juniper Networks as part of the QFX10000 series. Designed for demanding spine and core deployments, this 2-rack-unit (2 U) switch delivers very high throughput and flexible connectivity options, making it ideal for modern cloud, enterprise, and service provider networks.
Built on Juniper’s custom Q5 ASIC silicon, the QFX10002-36Q-DC offers up to 2.88 Tbps of switching capacity while supporting a mix of 10 GbE, 40 GbE and 100 GbE port speeds from its 36 QSFP+ interfaces (with QSFP28 compatibility for 100 GbE). This combination of density and multi-rate flexibility enables network architects to support evolving bandwidth needs without requiring frequent hardware refreshes.
Running the proven Juniper Junos OS, the switch delivers rich Layer 2 and Layer 3 features, advanced network virtualization support, and strong operational automation capabilities — all with the reliability and management consistency expected across the QFX family. The DC variant is tailored for direct current power environments, which are common in large data centers and carrier facilities.
