PTX3000 Packet Transport Router

The PTX3000 Packet Transport Router provides a high-density 8-Tbps core router in an ultra-compact form factor optimized for space- and power-constrained service provider environments. The platform supports the full range of IP/MPLS applications, including Internet backbone, peering, label-switching router, and metro packet optical transport for regional cores, space-constrained central offices, and collocation facilities.

The eight-slot, 22 RU PTX3000 router supports up to eight FPCs, each providing one PIC. It brings the best of the IP and optical worlds together, offering the flexibility of a full-featured IP network with the reliability, performance, and scale of optical transport, all in a single converged router.
