Compatible SFP+ and DAC Cable Solution For MikroTik CSS326-24G-2S+RM Switch
Feb
Overview of CSS326-24G-2S+RM
The MikroTik CSS326-24G-2S+RM was first released around mid-2017. It quickly became a popular choice for offices and labs looking for a cost-effective managed switch with Gigabit ports and SFP slots for fiber uplinks.
Cloud Smart Switch 326‑24G‑2S+RM is a SwOS-powered 24-port Gigabit Ethernet switch with two SFP+ slots in a 1U rackmount case that provides wire-speed connectivity and several handy switching features. What makes the CSS326-24G-2S+RM stand out from basic unmanaged switches is that it gives you all the core features you’d expect from a managed switch — plus a little extra control. Instead of just throwing packets around, it lets you shape and manage traffic, apply filters, and configure VLANs, all from a simple web interface in your browser.
The SFP+ slots support both 1.25 Gb SFP modules and 10 Gb SFP+ modules, giving you flexibility to build fiber links or uplinks as needed. The device comes with the operating system preinstalled and licensed, so there’s no extra software to buy — it’s ready to use right out of the box. Free SwOS updates are included for the life of the product or for at least 5 years from purchase.
Key Features of the CSS326‑24G‑2S+RM
#1 Hardware Overview
The switch has 24 Gigabit Ethernet ports and two SFP+ slots for 10G fiber uplinks — all in a standard 1U rackmount chassis, making it a solid choice for small to medium racks.
#2 Switching and Management
Powered by MikroTik’s SwOS, this switch does more than basic switching. SwOS lets you manage port-to-port forwarding, apply MAC filters, configure VLANs, mirror traffic for troubleshooting, limit bandwidth on ports, and even tweak some MAC and IP header fields — all through your browser.
#3 Fiber Flexibility
Both SFP+ slots accept standard 1.25 Gb SFP modules and 10 Gb SFP+ modules, so you can mix traditional fiber optics with high-speed uplinks as needed.

Conclusion
Compared with switches like the Ubiquiti UniFi US-24-250W, the CSS326-24G-2S+RM feels more relaxed when traffic gets busy, and the extra 10G SFP+ ports give you more room to play with fiber links. You can choose different optics for uplinks instead of being locked into one setup.
Overall, this is a simple two-layer switch. It’s about stable switching, simple SwOS management, and flexible fiber connections. Nothing fancy, but everything works as expected. If you’re looking for full Layer-3 features or a big controller system, models like Cisco Catalyst or Juniper EX make more sense. But for everyday use with Gigabit ports and a bit of 10G fiber, the CSS326-24G-2S+RM is an easy and practical choice.
