Avoid during optical cable laying
Avoid placing fiber optic cables in raceways and conduits with copper cables to avoid excessive loading or twisting. Cables do not have a flex rating. Routing on a cabinet door should be used as a last resort. They are installed in the same general location by the same people for the same general purpose. NOTE: The below considerations are not intended to encompass all installation practices. Proper industry. Where reels are supplied with protective material fitted over the cable, the protection should remain in place until the cable will be installed. Turn-backs and all sharp changes of direction. Executive Summary: Fiber optic cable failures cost enterprises an average of $15,000 per hour in network downtime—yet most catastrophic losses stem from a handful of preventable installation errors.
