The Juniper Networks® PTX Series Packet Transport Routers transform the core network with physical and virtual innovations that deliver unprecedented scale at the lowest cost per bit. Two fixed-configuration platforms are available: the PTX10001-36MR Packet Transport Router, a compact, power-optimized 400GbE platform based on custom Express4 silicon; and the PTX10003, the industry’s first 3U 400-GbE enabled packet transport routing device. These transport routers give cloud and communication providers the freedom to develop and deliver new virtualized services anywhere in the network with elastic architectures and precise traffic controls, without compromising the service experience.
