As of today BMD has a recommendation of which cable to use for there 12G-SDI products..
https://www.blackmagicdesign.com/support/faq/59012
Belden 1694A is a cable that excists for 20 years now(1995). Approved for 1,5G SD/HD-SDI signals in the first place. In the official table of Belden they say 3G - 155m 6G - 105m 12G - Not listed as in not recomended for 12G. So if BMD does tests with Belden 1694 and they can go to 50 meters that is very nice But officially belden says it is not supported..
But you could buy much better optimised cables for 12G, which gives you more cable length.
I would like to compile a list with cables you guys are using as a reference to other users.
Personally i use Sommercable SC Vector 600-0162 with Neutrik UHD 12G connectors in my OBV.
Also keep in mind that normal BNC connectors are not made for these high frequencies and will affect the useable length of the cable in great length. The isolation materials between the shield and the pin need to be optimised for high frequencies to give you the best results without to much interference or dropouts.
Tell me what you guys are using. I will add it to this begin post as a reference!

It is important to use a good quality HD cable with 12G-SDI products. As an example, we have used an industry standard Belden 1694A cable when testing our 12G-SDI products.
Distance for cable lengths are:
3G-SDI 100 meters
6G-SDI 80 meters
12G-SDI 50 meters
