The MikroTik CRS310‑1G‑5S‑4S +IN 10G SFP+ switch is a powerful and compact Layer 3 capable switch designed for high-speed fiber networks in indoor environments. It features 1 Gigabit Ethernet port with PoE-in, 5 SFP ports for 1G fiber connections, and 4 SFP+ ports supporting 10G fiber, making it ideal for building efficient aggregation or access layer setups.

Powered by a Marvell 800 MHz CPU, with 256 MB of RAM, this switch offers a switching capacity of 162 Gbps and non-blocking throughput of 81 Gbps, supporting hardware-based VLAN filtering and partial Layer 3 routing. It includes dual power input options (DC jack and PoE-in), active cooling via an internal fan, and operates within a wide temperature range.

The CRS310 supports dual boot between RouterOS and SwOS, giving users flexibility between advanced routing features and a streamlined switching interface. Its fan-assisted 1U case and rackmount kit make it an excellent choice for small to medium business networks, ISPs, or lab environments requiring reliable, high-speed fiber connectivity.
