I believe it is a standard tranceiver. I took it out of the modem I got from the ISP, put it into a mediaconverter and plugged the ethernet cable into the router. Worked right away, with the WAN side set to DHCP and no VLAN.
I have two fibers comming from the ISP. One for internet, apparently with no VLAN, and a separate for TV, RF over filber. The fiber is just plugged into a metal box with power and an F-connector. I don't have TV from my ISP so I just removed the whole router assebly and coiled the fibers into a termination boks with a SC to SC adapter so I can run a patch cord to the tranceiver.
The reason for the original question was that I'm trying to minimze the number of boxes. If I can plug the tranceiver into either my router or the switch, that's one box less. I think the reason for it not towork is because the tranceiver isn't coded to HPE.
Looks like this BTW:
FS.com told me that this should work:
