I had a giant spool of fiber cable in my garage (about 1/2" thick cable, 12 strand burial 62.5 multimode) - 62.5 is pretty obsolete. Guys come around garbage night picking up scrap metal from homes on the street.... I tried leaving the giant spool of fiber out before and they knew it was fiber so they didn't take it. I waited a few months, I wrap a little bit of 24 pair cat 3 telephone cable on the very outer layer, BAM! entire 180lbs fiber spool gone by the metal guys! They got a few feet of copper, and a whole bunch of useless fiber, I was so happy!
Remember, spool was heavy, took up too much space, I don't feel like having Kijiji/Craigslist people come to my home - I just wanted it gone. Cat 3 24pair?... no tears shed over that either.
