I would like to use a hEX S in 2 scenarios:
1. with SFP for the WAN with 10/100 MBit fiber.
2. with SFP for the WAN with 10/100/1000 MBit copper.
My questions are:
1. Is the an SFP for the hEX S that will support 10/100 MBit fiber? Either MikroTik SFP or another brand?
2. According to the MikroTik SFP compatibility chart, it appears that the S-RJ01 copper ethernet SFP
only support 1000 Mbit, not 10 or 100 MBit in the hEX S. Is this really true? If so, is ther another vendor's
copper SFP that will support 10/100 or 10/100/1000 Mbit, or is this a true limitation of the hEX S?
Thanks.

You should be able to force the speed and the negotiation in the SFP interface settings. So a 1Gb fiber interface should be able to be set for 10/100Mb and the same for the 1Gb copper interface.
