Cisco SD-AR1K-88H24FHE 36x QSFP-DD 12 Tbps Linecard | 8800, Enterprise

Push more traffic through fewer slots with a Cisco 8800 linecard engineered for dense, high-throughput switching. The SD-AR1K-88H24FHE provides 36 QSFP-DD ports and 12 Tbps of capacity, giving infrastructure teams the port density needed to scale leaf-spine fabrics, core aggregation, and high-performance network backbones without multiplying chassis footprint. This is the kind of component that matters when port count and forwarding capacity are both under pressure. QSFP-DD support gives you room for modern high-speed optics and breakout strategies, while the 12 Tbps design target supports demanding east-west traffic patterns and large-scale uplink concentration. For teams standardizing on Cisco 8800 platforms, the value is in preserving architectural consistency while adding meaningful headroom. It is a linecard for environments where replacement cost is measured against downtime, rack space, and future expansion. If the network is carrying critical workloads, this class of hardware is chosen to keep the fabric fast, dense, and ready for growth.
