I spoke with Adrian about these. There will be two versions of each card. One with onboard 10mhz to 25mhz synthesizer on Pcb, another which will accept a direct 25mh clock input (from something like the sclk board) and no onboard synthesizer.@Jake2
This is one new product . There is a sft version coming as well . I'm really keen as I've never tried optical to my server and have a few unused outs on my ock-2

The external power input only powers the clock synthesizer. The cards with direct 25mhz input will not use external power.
Also, price of SFP card will be similar to the Ethernet card.
