Compact metallic network switch with multiple ports and rack ears

Mikrotik

Mikrotik CRS309-1G-8S+IN Surge Protector

SKU CH-YQH7-9D5AJ

A compact switch with eight 10 Gbit SFP+ ports, 162 Gbps switching capacity and fanless metal housing

  • 162 Gbps switching capacity for high-density 10 GbE links
  • 81 Gbps non-blocking throughput handles full line-rate traffic
  • Passive cooling via metal enclosure eliminates fan noise and dust
  • Dual-core 800 MHz CPU with 512 MB RAM runs RouterOS or SwOS
  • Industrial temperature range -40 °C to +70 °C for harsh environments

Compact 10 GbE Switch

The MikroTik CRS309-1G-8S+IN is a passively cooled switch with eight SFP+ slots, each supporting 10 Gbit modules. It delivers 162 Gbps switching capacity and 81 Gbps non-blocking throughput. A dual-core 800 MHz CPU with 512 MB RAM runs RouterOS or SwOS. The metal enclosure acts as a heatsink for silent operation.

Ideal for High-Density Fibre Links

Network engineers needing many 10 GbE ports in a fanless, rack-mountable unit will value the eight SFP+ interfaces and dual-boot flexibility. Sites requiring active cooling, built-in copper ports beyond the single management link, or integrated surge protection should evaluate other options.

Eight SFP+ Ports Decide Fit

The single specification that determines suitability is the count of SFP+ slots: eight ports each accepting 10 Gbit modules. If the installation needs more or fewer high-speed fibre interfaces, this model is not the right part.

Questions about this item

What SFP+ modules do I need to populate the eight 10 Gbit ports on this switch?

Each of the eight SFP+ slots accepts a 10 Gbit module; choose single-mode or multi-mode transceivers that match your fibre type and distance requirements.

Can I keep my existing 1 Gbit copper uplinks when adding this switch to the rack?

The single management Ethernet port operates at 1 Gbit and can serve as a copper uplink while the eight SFP+ ports handle 10 Gbit links.

How do I verify the switch is passing traffic at the rated 81 Gbps non-blocking throughput after installation?

Use the SwOS or RouterOS interface to monitor per-port counters; sustained aggregate traffic approaching 81 Gbps confirms non-blocking operation.
