FG-1100E datasheets mentions the following :

-Hardware Accelerated 25 GE SFP28 /10 GE SFP+ Slots

Q1-Does this mean those built in ports supports both 10/25 GE speeds based on SFP type used ?

Q2-If target is 10G Speed ,  Does those builtin ports ports support  (  FG-TRAN-SFP+LR  : 10 GE SFP+ Transceiver Module, Long Range )  , Or must use  ( FG-TRAN-SFP28-LR : 25 GE SFP28 Transceiver Module, Long Range  )  ?
