The Juniper PTX10000 line of modular routers, including the PTX10004, PTX10008, and PTX10016, sets the benchmark for ultra-high-density 400GbE and 800GbE performance in the cloud and AI era. Powered by the groundbreaking Express 5 silicon, these platforms deliver an industry-leading 28.8 Tbps of forwarding capacity per line card slot, enabling the 16-slot PTX10016 to scale up to a massive 460.8 Tbps per chassis. Designed for maximum versatility across core, peering, and AI data center networking, the PTX10000 series features native wire-rate inline MACsec encryption, a 10M+ FIB, and comprehensive SRv6 support without compromising power efficiency or latency. With a midplane-less orthogonal architecture that ensures a seamless migration path from 100G to 800G and beyond, this modular family provides the sustainable scale, operational excellence via Junos OS Evolved, and long-term investment protection required for the world's most demanding wide-area and data center fabrics.
