Yes they will interoperate.   Make sure the wavelength matches.  i.e.  make sure both 10G transceivers are SR or LR, etc.
Hi, My server room  primarily a Dell PowerConnect office, but we're looking into buying some Cisco switches. Currently I have 4 PowerConnect 6248 switches in my server room connected using a stacking cables.  What would be the best recommended cable to connect a Cisco 4500 series switch (or any Cisco switch) to my existing Network?  Do the 10GB modules cooperate with Cisco switches? Should I just use Multiple Fibre Channel cables?  Much Appreciated Nick
