The T4000 Core Router is a true multiservice core routing system that delivers a reliable, high-performance, and flexible architecture to carry a wide breadth of services over a common IP/MPLS infrastructure.
With 3.84 Tbps of line rate throughput in a half rack chassis, the T4000 offers double the slot capacity of the nearest competitor. It delivers 240 Gbps per slot, and supports up to 208 ports of 10GbE or 16 ports of 100GbE interfaces, making it the densest line-rate IP/MPLS routing system.
