The MikroTik CRS305-1G-4S+IN is a compact cloud router switch designed to bring high-speed connectivity to small networks. It features four SFP+ cages providing 10 Gbit per port, while also supporting 1.25 Gbit modules for greater flexibility in your fiber connections. A single copper Ethernet port handles management tasks or traffic forwarding, and the device can be powered via passive PoE through this same port. One of its most versatile features is the dual boot capability, allowing you to choose between RouterOS and SwOS depending on whether you need advanced routing or simple switching. The hardware is housed in a silver metallic case measuring 141 x 115 x 28 mm, which remains completely silent during operation thanks to its fanless cooling design. To ensure reliability, it includes two redundant DC jacks supporting an input voltage range of 12-57 V. This desktop unit is built for demanding environments, operating reliably in temperatures ranging from -40 °C to 70 °C. It is a practical choice for users who need a quiet, high-throughput backbone for their home lab or small office without the noise of traditional rack-mounted equipment.
