I recent purchased some TP Link products to create an Omada system
plus more and various fiber cables

I have a question that i cannot seem to get a clear answer to,

i have some legacy sfp ports which i want to use in the network as a whole, 

Can an SFP transceiver use OM3 multi mode cable?  

Would there be a draw back from using OM2 multi mode fiber cable?

Will my SFP+ ports support an TP Link SFP transceiver ( used on a legacy sfp port and another sfp identical into a SFP+ port work?  (assuming manual select of speed ?)

I am tying the SFP+ router port(s) with the SFP+ switches with these 

10GbE SFP+ DAC Twinax Cable, 10Gbase-CU SFP+ Passive Copper Cable

the SFP switch uses the SPF port on the router to one of its SFP port.

all RJ45 cables are CAT 8 with POE

  Any clarity on these issues would be appreciated.
