So we are using more and more fiber on the job. I'm finding it harder and harder to manage the stuff. We have InterDuct between the racks and term shelves. But in the racks I don't have a good solution for keeping it all neat and organized. Ethernet wire management won't do the trick... The so called "fiber tray" we got from cisco is a joke, which pains me... We have already had problems with jumpers being damaged from improper management.
Velcro. You can buy it in bulk spools relatively cheap, and cut ties to length. Plus you can reuse ties forever, and it doesn't create pinch-points in the fiber like zipties can. Roll up service loops per fiber pair, and stash them wherever it's convenient.
Assuming you don't need to access the fibres very often and are more concerned with keeping it safe and secure, then I'm with jstretch. Velcro ties every 6 inches or so, on both vertical and horizontal runs, gathering the fibres into sausages. Most of your velcro ties would be free with the occasional one here and there fixed to the rack to hold the whole thing in place. If you have unique labels at each end you could even trace fibres through without having to move them
