https://edeskv2.belden.com/products/index.cfm?event=showproductdetail&partid=1820 Specs show ~8db of attenuation per 100ft. at 3GHz (your 3Gbps data rate with 8b/10b would actually be lower loss than this. So for 100 meters, loss would be about ~26dB. That's pretty good. However, it requires a fairly good cable equalizer at the other end. Stratix IV GX maximum equalization tops out at 16dB. You'll need an external cable equalizer (which would be wise regardless). Jake
