Cisco WS-C3850-12S-E 12-Port Gigabit SFP+ Switch

Usage Area

The Cisco Catalyst WS-C3850-12S-E is a fixed-configuration enterprise access switch designed for deployment in local area networks (LANs) within medium to large campus environments. It is primarily utilized for aggregation and distribution layer roles, supporting high-density Gigabit Ethernet connectivity for server farms, core network links, and uplink connections. The switch is suitable for organizations requiring advanced IP services, including policy-based routing and enhanced security features. Its SFP-based fiber ports enable long-distance connectivity between wiring closets and backbone infrastructure.
