    Hi Peter, I was able to find LC-LC single-mode 9/125um Corning duplex fiber from LanShack. 30M is only $38. I'm going to order some. Thank you for the recommendation.

    It's accurate that digital is prone to the influence of many different noise factors, some, but not all of which, are vibration, cables, power, etc. I don't agree about fiber, but whatever floats your boat. Lest we forget, this is just a hobby...

    The other switch to consider is the SOtM sNH-10G. They also have two optical transceiver SFP cages. You can also get them with the SOtM SCL-EX clock board for an extra $700; the SOtM SCL-EX clock board is really an excellent clock.
