Fiber-optic cable supports up to 1000 stations and can carry the signal up to
and beyond 2 kilometers. Fiber-optic cables are also highly secure from outside
interference, such as radio transmitters, arc welders, fluorescent lights, and other
sources of electrical noise. On the other hand, fiber-optic cable is by far the most
expensive of these cabling methods, and a small network is unlikely to need these
features. Depending on local labor rates and building codes, installing fiber-optic
cable can cost as much as $500 per network node.
