MikroTik CRS310-1G-5S-4S+IN Switch

MikroTik CRS310-1G-5S-4S+IN Switch : FiberDriven Precision for Modern Networks

Networks are no longer simple chains of connections. They are ecosystems. Dense, fast, and unforgiving of inefficiency. The MikroTik CRS310-1G-5S-4S+IN Switch is engineered for these realities, where fiber reigns, latency matters, and flexibility defines success.

Compact yet formidable, this switch blends Gigabit Ethernet, SFP, and SFP+ interfaces into a single, elegant chassis. It is a device that speaks fluent fiber. Quietly powerful. Meticulously controlled. Designed for environments where performance is expected, not negotiated.

MikroTik CRS310-1G-5S-4S+IN Switch

The MikroTik CRS310-1G-5S-4S+IN Switch is a Layer 3 capable switch built to handle highspeed aggregation, backbone links, and advanced routing scenarios. With five 1G SFP ports, four 10G SFP+ ports, and one Gigabit Ethernet port, it bridges the gap between access and core layers with remarkable agility.

Driven by an 800 MHz ARM CortexA7 CPU and supported by 512 MB of RAM, this switch operates smoothly under heavy traffic loads. RouterOS provides granular control over switching, routing, VLANs, and security policies. Rackmountable and powerefficient, it fits neatly into professional network racks without drama.

This is not a passive piece of infrastructure. It is an active participant in network intelligence.

Key Features of the MikroTik CRS310-1G-5S-4S+IN Switch

Every element of this switch is tuned for modern fiber centric deployments:

• 4 x 10G SFP+ ports for ultrafast backbone and aggregation links
• 5 x 1G SFP ports for flexible fiber connectivity
• 1 x Gigabit Ethernet port for management or copperbased access
• ARM CortexA7 CPU at 800 MHz for stable Layer 3 processing
• 512 MB RAM enabling advanced configurations and traffic handling
• RouterOS support for switching, routing, VLANs, and firewall rules
• Rackmountready design for professional installations
• Low power consumption with a maximum of 15W
• Universal power input (100–240V) for global compatibility
• Compact, efficient chassis engineered for dense network environments

Together, these features make the CRS310 a fiberfirst switch with intelligence baked in.
