CableProject USA offers a free trial and a YT demo video. I can't vouch
for it, never having witnessed it in operation personally, but it looks
interesting.

Cable Management Software runs the full gamut, from simplistic to
near-ERP in scope, while others (e.g., VPI) also perform
autoconfiguration and coordinated, parametric link designs for specific
types of hardware (WDM, Switches/Routers, ROADMs, etc.). One can spend
anywhere from free to $29.99 to tens of thousands of dollars, so decide
carefully what you need, know specifically what you're looking for, and
most of all, caveat emptor.
