I've blown-pushed-rodded-trenched-plowed-directional bored-lased-ADSS and pull fiber in ducts. I find it hard to believe this was one continous length of fiber. What was the size / count of the fiber cable, I'd think the weight would eventually drag it down. 21 mile between repeaters is really pushing it. Was the reel pre tested before the installation. what type of brakes were on the reel, did it free wheel or was it feed. Not questioning your comment, would just like more info for future use................Take Care: be safe
