MikroTik CRS305-1G-4S+IN – Compact 10G Switch for SMB Networks

MikroTik CRS305-1G-4S+IN is a compact desktop switch with four SFP+ 10 Gbps ports and one Gigabit Ethernet port, designed for home labs, small offices, and infrastructures where high-speed optical switching is needed in a silent, unobtrusive form factor. With power redundancy through two independent DC inputs and dual boot RouterOS/SwOS support, it delivers complete flexibility at a price-to-performance ratio that stands out in the desktop SFP+ switch category.

All four SFP+ slots support modules up to 10 Gbps each — covering short and long-range optical connections as well as DAC cables for direct-attach interconnects. The dual-core 800 MHz CPU with 512 MB RAM provides stable processing and smooth management including Layer 3 configurations with active routing. Two independent DC inputs deliver power redundancy without additional hardware — if one fails, the other takes over automatically. The Gigabit Ethernet port covers out-of-band management or standard traffic for an additional device. The compact fanless metal enclosure ensures completely silent operation.

CRS305-1G-4S+IN supports dual boot between RouterOS license level 5 and SwOS — a choice between a fully featured managed switch with Layer 3 routing, VPN, and firewall capabilities and a streamlined interface focused exclusively on switching functions. The preferred operating system can be selected from RouterOS, SwOS, or directly from RouterBOOT settings. It integrates into existing networks as a 10G aggregation switch, core switch for home lab environments, or optical distribution point in small infrastructures.

Recommended for home labs with 10G switching requirements, small offices with existing SFP+ infrastructure, NAS storage networks requiring 10G connectivity, and any scenario where a compact, silent SFP+ switch with power redundancy and dual boot flexibility is the priority. RouterOS level 5 license and free lifetime software updates are included.
