sfp-25g-sr-s alternatives I work at a media company and we have a room where we're essentially having a spine leaf topology implemented for our network. Now there's 4 spine switches and 6 leaf switches, the sfp we're using are the 25g-sr-s modules, but I've been told we can save money by having a cross connect since the switches will be in the same room. ![enter image description here]( Can someone help me explain how this would work? that's if it's possible at all Cheerio

You can save money by purchasing so-called DAC (direct attach cable), but it has it's own limitations and most of the time requires that equipment is located realy close one to each other. Length of those cables are often below 10m.

Also there could be limitations based on your switches (they can support as example of maximum 2-3m DAC on 25G). I suggest you to spend some time and maybe ask your integrator (if you have one) or search info about available DAC for your equipment and their limitations.
