The CN 5140 features a high-capacity switching fabric with 24 Gigabit Ethernet (GbE) ports in a compact 2 RU form factor that allows front access to power and all system interfaces. The CN 5140 has an extended temperature range (-40 to +65C) and a robust physical design that supports deployment in a wide variety of unconditioned environments, including GR-487 and ETSI-compliant outdoor cabinets. Because the switch provides both SFP and RJ-45 connectors for each of its 24 GbE interface ports, the CN 5140 can support service aggregation, transport, and demarcation applications in a wide variety of network topologies, including fiber and microwave rings, point-to-point fiber, microwave mesh, fiber or copper to subscriber, MTU/MDU/FTTx, and more.
