The fiber optic cable you just installed failed testing. What do you do next? How do you find the problem and fix it—fast? Fortunately, fiber optics is easy to install and experienced installers generally find that about 95 percent of all fibers they install will test good.
Last month, we discussed “dark fiber” and how most outside plant installations include more fibers than are needed at the time of installation. Later, those fibers will be used for expanding service capacity or leased out to provide income.
