MIC-3D-40GE-TX Use Case
Enterprise Campus Core: High-Density Gigabit Aggregation with MIC-3D-40GE-TX-40x10/100/1000 RJ-45 MIC
In a large enterprise campus environment with 200+ Gigabit access switches, deploying the MIC-3D-40GE-TX adds 40 fixed 1 Gb RJ-45 ports to the core distribution switch. This consolidation reduces chassis count, simplifies port management and cable runs, and provides a clear upgrade path to 40 Gb uplinks. Outcome: optimized rack density, lower operational costs, and future-proof campus backbone performance.
Data Center Leaf Switch Expansion: Scalable Server Connectivity Using MIC-3D-40GE-TX
Hyperscale data center operators install the MIC-3D-40GE-TX in leaf switches to gain 40 additional 1 Gb copper ports for direct server attachments. The full-height, fixed-optics design eliminates the need for intermediate patch panels and reduces Top-of-Rack switch count. Outcome: accelerated deployment, reduced power and cooling overhead, and streamlined port scalability for high-density server farms.
Service Provider Edge: Rapid Multi-Customer Aggregation with MIC-3D-40GE-TX
A global service provider equips remote edge routers in 150+ branch locations with the MIC-3D-40GE-TX to terminate customer circuits over 40 RJ-45 Gigabit interfaces. This single-card solution accelerates on-site provisioning, enforces per-port QoS, and maintains strict SLA compliance. Outcome: faster time-to-revenue, standardized field operations, and reduced truck rolls for edge network expansion.
