I was looking for something similar about 18 months or so ago. Although I haven't taken any action yet, I concluded that one could do a nice job for under $200 per segment, including the transmitter and receiver modules and lots of connectorized multimode fiber. What I *don't* know is what the phase noise performance would be, except that I do know that the fiber's VF *is* materially influenced by temperature.
I was looking primarily at the HFBR-2416 for the fiber receiver, and the HFBR-1412 (standard power) or the HFBR-1414 (high power option) for the transmitter Unlike most of the available models, these are fundamentally analog devices, meaning that you can transmit sinewave 10 MHz through them. At the time I was looking, Mouser was selling these for about $20 each. See the datasheet at https://www.mouser.com/datasheet/2/678/AV02-0176EN_2019-02-15-1827546.pdf with particular attention to page 21 regarding the HFBR-2416 receiver. I was also looking at Fiber Instrument Sales for patch cords. We bought a lot of fiber stuff from them at Arecibo, and I was always happy with them. See: https://www.fiberinstrumentsales.com/catalog-cable-assemblies?gclid=Cj0KCQjwvaeJBhCvARIsABgTDM7eNTkP2nQbyFzhcwDE38VnSEP879MBKV1ZyDq2YrnEtOn7_VfzjbkaAtpfEALw_wcB Somebody had pointed out yet another source of connectorized fibers ("patch cords") to me, but I cannot find the name at the moment.
