Cisco ASR 9000 2-Port 100GE Modular Port Adapter | Enterprise Routing — SD-AR3K-A9KMPA2X

Expand ASR 9000 routing capacity with a 2-port 100GE modular port adapter designed for high-speed service aggregation and backbone transport. This Cisco module fits environments that need more bandwidth without redesigning the routing layer, making it a practical choice for service providers and large enterprise networks running demanding traffic profiles. By adding two 100 Gigabit Ethernet ports in a modular form factor, the adapter supports dense uplink expansion where throughput and slot efficiency are critical. It is suited for teams standardizing on the ASR 9000 platform and looking to preserve operational consistency while increasing interface capacity. This is the kind of component that justifies itself in production networks: it extends the life and utility of an existing chassis, supports higher traffic growth, and keeps expansion aligned with the platform already in place. For infrastructure teams balancing performance, scale, and procurement discipline, it offers a focused path to more bandwidth without unnecessary platform sprawl. Ideal For Expand ASR 9000 uplinks in a carrier edge routing deployment Add 100GE capacity to a backbone aggregation chassis Increase port density in a high-traffic service provider core Extend the useful life of an existing ASR 9000 investment Why This Product 1 Adds 2 x 100GE ports for dense uplink expansion 2 Fits ASR 9000 modular routing environments 3 Preserves chassis investment versus platform replacement 4 Targets carrier-grade aggregation and backbone scaling
