I realize that it's expensive to run these lines but when you put your
working and protect in the same cable or different cables in the same
trench (not even a trench a few feet apart, but the same trench and
same innerduct), you have to EXPECT that you're gonna have angry
customers. And yet when telco folks learn that this has occured, they
often fein being as surprised as the customers.


Has anyone calculated what the cost of doing this correctly once vs the ongoing support/SLA/etc issues of repairing it when it goes boom is? I've gotta believe that for >90% of the situations where diverse routes exist, just being used as dual linear paths, its cheaper in the long term to do it "right" and cut the size of your outside plant crew (assigned to break/fix) by 90%. :)
