Re: [casper] Timing distribution over fiber

Jason, Mike, Jonathan, others!, White rabbit, and PTP are both pretty interesting. My suspicion is that it may end up being no more expensive and less worrysome (if not necessarily actually better) to distribute PPS/ some ref. clock directly, but HERA is a good excuse to investigate these

Re: [casper] Timing distribution over fiber

Hi Bob, Sounds interesting -- for what it's worth, I've just learnt some fellow astronomers in Italy (Andrea Maccaferri at INAF's Medicina observatory) have built some PPS/refclk distribution systems based on the Avago fiber parts -- perhaps you might be interested in getting in touch with him...
