Cisco 1-Port 10GE LAN-PHY Shared Port Adapter | Enterprise Ethernet — CON-L1NBD-IR809GLN

Move critical traffic onto a faster uplink path with this Cisco 1-port 10GE LAN-PHY shared port adapter. It is designed for environments where port density, predictable throughput, and platform fit matter more than generic expansion. By adding a single 10 Gigabit Ethernet connection, it helps keep storage, virtualization, and core application traffic moving with less congestion at the edge. This adapter is a practical choice when you need to extend a Cisco system without changing the broader architecture. The shared port design keeps the footprint focused, while the 10GE LAN-PHY interface supports higher-bandwidth connectivity for workloads that have outgrown standard Gigabit links. For procurement teams, it offers a targeted upgrade path; for engineers, it preserves alignment with Cisco hardware ecosystems. Use it when a single high-speed port is enough to close a performance gap, connect to a faster aggregation layer, or standardize uplinks across deployed systems. It is the kind of component that earns its place by solving a specific bottleneck cleanly and without excess. Ideal For Add a high-speed uplink to a Cisco edge or branch platform Upgrade a constrained Gigabit connection to 10 GbE Connect a Cisco system to a faster aggregation or distribution layer Standardize a single high-bandwidth port for traffic-heavy workloads Why This Product 1 Single-port design keeps expansion focused 2 10 GbE support provides more uplink headroom than Gigabit adapters 3 LAN-PHY host interface aligns with Cisco platform requirements 4 Shared port architecture suits targeted infrastructure upgrades
