Height of power fiber optic cables spanning the highway
FIBER OPTIC CONSTRUCTION STANDARDS
Fiber optic cable sequential numbers are required at each pole location and vault wall. Sequential numbers will identify conduit length, and slack left in vaults and at poles.

FOA Standard For Installing Fiber Optic Cable Plants
While fiber optic cables generally are all dielectric and carry no electrical power, it may be necessary to work in areas that have installed electrical power cables and hardware.
Required Clearance for Electrical Lines Over Roads under National
Because of the risk of injury posed by overhead electrical lines, the National Electrical Safety Code (NESC) publishes strict guidelines for height clearance over roadways.
