Why fibre optic? You'll only need to convert back to copper when you get it in there (unless the kit that needs the 10Mhz reference has optical 10MHz in), and if you do that you may as well just take it in there using high quality coax (say RG-400U) and a bulkhead connector in the wall of the room.

Hi all, I have to carry a 10 MHz standard frequency signal inside an EMC screened room via fiber optic cable. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
