Mikrotik CRS310-1G-5S-4S+in 5 x SFP Ports 4 x SFP+ Ports and 1 x Gigabit Ethernet Port

The MikroTik CRS310 is a compact Cloud Router Switch designed for indoor fiber aggregation in ISP, SMB, and lab environments. With a mix of 10G SFP+ and 1G SFP ports, it offers a practical upgrade path for networks transitioning from Gigabit to 10 Gigabit fiber while maintaining low latency and stable performance. Where the CRS310 is commonly used Equipped with a modern ARM v7 CPU, 256 MB of RAM, and Marvell switch chips, the CRS310 delivers reliable performance for mixed 1G and 10G fiber workloads. Hardware-offloaded VLAN filtering and selective Layer 3 routing help reduce CPU load while maintaining predictable throughput. The CRS310 features five 1G SFP ports, four 10G SFP+ ports, and a dedicated Gigabit Ethernet port connected directly to the switch chip for full Gigabit throughput. PoE-in support provides flexible powering options for deployments where traditional power access is limited. Designed for indoor use, the CRS310 can be mounted in a standard 1U rack to keep network infrastructure organized. Optical fiber support makes it a strong alternative to copper in environments where electromagnetic interference, security, or distance are concerns. 4 10G SFP+ ports 5 1G SFP ports 1 Gigabit Ethernet port PoE-in support Hardware-offloaded VLAN filtering Partial hardware Layer 3 routing RouterOS or SwOS support Rack-mountable (1U) Designed for indoor environments Need help choosing the right CRS switch?See our CRS switch guide
