MikroTik Cloud Router Switch 5 Port SFP 4 SFP+ | CRS310-1G-5S-4S+IN

The MikroTik CRS310‑1G‑5S‑4S+IN is a compact yet powerful Layer‑2/Layer‑3‑capable fiber switch featuring five 1 Gbps SFP ports, four 10 Gbps SFP+ ports, and a Gigabit Ethernet uplink with PoE‑in support. Powered by an ARM v7 dual‑core 800 MHz CPU and 256 MB RAM, it delivers hardware‑offloaded VLAN filtering and even some hardware‑accelerated L3 routing, offering exceptional performance for indoor fiber distribution and small ISP backbones. Its modern Marvell switch‑chip ensures low‑latency, high‑throughput operation, while improved cooling and a compact 1U‑rack‑mountable design make deployment clean and efficient. Dual‑input powering (18–57 V DC jack or 802.3af/at PoE‑in) provides flexible installation options even in challenging environments. Ideal for extending 10 Gbps fiber links over 100 meters, the CRS310‑1G‑5S‑4S+IN offers a robust, cost‑effective upgrade path for CRS212 and other legacy fiber switch setups.
