And, in a situation where the plastic fiber is just getting the databits from A/D into computer, as long as the BER is reasonably low, it works. You're not worried about actually using the fiber for accurate timing, just as a data transport. BTW, the scenario of broken fiber held by the jacket is very close to the one failure I've had with plastic fiber. _______________________________________________ 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.
