Different Ways to Install Fiber
We’re all familiar with the usual ways to install fiber—trenching and burying cable or placing cable on poles outdoors and placing cables in trays or conduit indoors. But there are many other ways to install fiber optic cable that are sometimes easier and more economical. How familiar are you with those techniques?
1. Outdoor cables can be direct buried without conduit outdoors if they are of the ______ type.
Correct Answer: Armored
2. Direct buried cables can be plowed in with special equipment in one step if ______.
Correct Answer: All of the above
3. Electrical utilities can install power and ground cables that have fibers in the center of the cable.
Correct Answer: True
4. Electrical utilities can also install ______ cables on transmission towers near the power conductors.
Correct Answer: All dielectric self-supporting (ADSS)
5. In metro areas, contractors can use ______ to install ducts or cables in a small, shallow groove sawed in pavement on a roadway.
Correct Answer: Microtrenching
6. New smaller cables called microcables rely on two developments in optical fiber to pack more fibers in a smaller cable. Those two developments are ______ and ______.
Correct Answer: Bend insensitive fibers; smaller buffer coatings
7. Unlike regular cables that must be pulled into large ducts, microcables can be installed in microducts barely larger than the cable itself by ______.
Correct Answer: Blowing the cable in the duct
8. Blown fiber originally referred to blowing bare fibers into plastic tubes instead of today’s more common practice of blowing complete cables.
Correct Answer: True
9. The blown fiber technique actually uses air pressure to ______ and allow ______ into the duct.
Correct Answer: Reduce friction; pushing cables
10. New techniques that allow installing additional cables in currently used ducts include ______.
Correct Answer: All of the above
