The Cisco Catalyst WS-C3850-12S-S is a Refurbished enterprise-grade stackable switch built for demanding network environments. Equipped with 12 SFP (Small Form-Factor Pluggable) ports, this switch is purpose-built for fiber-based uplinks and high-density access or distribution deployments where optical connectivity is preferred over copper.
Running the IP Base feature set, the WS-C3850-12S-S supports essential enterprise routing and switching capabilities including static routing, EIGRP stub, and core QoS features — making it well-suited for structured campus and branch network designs. The Catalyst 3850 Series is also recognized for its support of full StackWise-480 stacking technology, allowing multiple switches to be combined into a single logical unit for simplified management and increased resilience.
Sourced and tested as a Refurbished unit, this switch has undergone inspection to ensure reliable operation, providing a cost-effective path to deploying proven Cisco infrastructure. It is an ideal choice for IT teams looking to extend the life of a tested platform, build out secondary network tiers, or deploy lab and staging environments without the premium cost of new hardware.
With Cisco's trusted IOS-XE software foundation and a compact fixed form factor, the WS-C3850-12S-S remains a dependable choice for fiber-first switching at the access or distribution layer.
