Ensuring Compatibility Between SFP+ and SFP28

Hardware MikroTik hardware general

I’m interested in purchasing the CRS518-16XS-2XQ-RM switch. I plan to utilize the SFP28 ports on this switch to connect to a CCR1009 and other switches with 10 GB support, such as the CSS326-24G-2S+RM. These devices also support 10 GB modules.

  1. Can I use a DAC 10Gb cable to connect an SFP28 port on the CRS518-16XS-2XQ-RM to an SFP+ port on the CCR1009 or other 10Gb devices?
  2. Is it possible to install an SFP+ 10GB module on one of the SFP28 ports on the CRS518-16XS-2XQ-RM and then use a fiber patch cord to connect it to an SFP+ 10Gb module installed on a CCR1009 or other MikroTik devices with SFP+ 10Gb modules?

Thank you!
