C3KX-NM-1G= Use Case

Campus Fiber Backbone Scalability

In a large enterprise campus environment requiring additional uplink capacity between distribution and core layers, network engineers install the C3KX-NM-1G=-Catalyst 3K-X 1G Network Module on Catalyst 3K-X switches to enable four 1G SFP fiber connections. This delivers scalable backbone throughput, simplifies future network expansion across multiple buildings, and ensures high availability with minimal re-cabling effort.

Data Center Edge Redundant Uplink Architecture

In a mid-sized data center deployment, IT teams equip edge Catalyst 3K-X switches with the C3KX-NM-1G=-Catalyst 3K-X 1G Network Module to create redundant 1G fiber uplinks to aggregation and core layers. The result is seamless failover with sub-second convergence, improved SLA compliance, and reduced risk of single-point failures for critical server traffic.

High-Definition IP Surveillance Over Fiber

A global retail chain integrates high-definition IP cameras across dispersed store locations by leveraging the C3KX-NM-1G=-Catalyst 3K-X 1G Network Module’s 1G fiber uplinks on Catalyst 3K-X switches. This enables long-reach, low-latency video transport, centralized monitoring, and minimal packet loss for enhanced security and operational efficiency.
