Thank you for this info, this is going to help me out a lot!! I am having to connect an IDF to the MDF, they are on 2 different floors, but one is right above the other and in cable run between the 2 is only about 20ft. I normally use fiber to connect the different closets together, but the price difference between the fiber and copper run is so big. I couldn't imagine paying for a fiber run for only 20ft. The draw back was the speed. I am using the MS225-48LP switches as well, and I know they have all 1gig copper ports, and usually i get the 10g fiber sfp modules for the up-links. I had been looking for a 10gig copper sfp module to use as the uplink between the 2 closets. I don't want the copper to be the bottle neck. So, thank you, I am going to give this a go!!
