the main problem with massive data transfer from radio astronomy sites to other places is not throughput in fiber, but economically purchasing transport capacity from carrier-of-carrier ISPs to get it from the place where the radio telescopes are at, to various research labs and datacenters. radio telescopes tend to be located in very remote places with very few dedicated dark fiber options. from the perspective of somebody in the ISP business, go try to buy a 100GbE transport circuit from $random_radio_astronomy_telescope_site to a meet-me room/traffic exchange point at a major internet infrastructure site.... you're going to run into economic problems really quick.
