Overview
Expand high-speed optical networking in compact setups with the MikroTik Cloud Router Switch CRS305-1G-4S+IN. Housed in a fanless, compact metallic enclosure, this desktop switch features four 10 Gbps SFP+ cages alongside a single Gigabit Ethernet copper port reserved for management or traffic forwarding. Featuring a "Dual Boot" operating system supporting both RouterOS and SwOS, multi-input power redundancy, and PoE-In functionality, it delivers exceptional 10GbE density and wire-speed switching throughput for small-office and lab deployments.
Key Features
- 10GbE SFP+ Optical Density: Features 4× 10 Gbps SFP+ cages supporting high-speed fiber transceivers and direct attach copper (DAC) cables (also compatible with 1.25 Gbps modules).
- Dedicated Gigabit Management Port: Equipped with 1× 10/100/1000 Mbps Ethernet port for quick Out-of-Band management access or regular routing.
- Dual Boot Operating System: Switch seamlessly between simplified SwitchOS (SwOS) for dedicated Layer 2 functions or full-featured RouterOS Level 5 for advanced Layer 3 routing and firewalls.
- Triple Power Redundancy: Powered via two redundant DC power jacks or via Passive/802.3af/at PoE-In on the Gigabit Ethernet port.
- Silent & Compact Metallic Enclosure: Fanless, passive cooling design ensures totally quiet operation suitable for noise-sensitive office environments.
- High Wire-Speed Performance: Delivers up to 41 Gbps non-blocking throughput and 82 Gbps switching capacity.
