Cable Feet
Cable feet is the length of a cable in feet. It is a term commonly used in DSL and other distance sensitive technologies to describe the length of the cable over which the signal must propagate.
Generally, the cable feet distance will be longer than the linear distance between two locations because usually the cable can not be run directly but must follow right-of-way such strung between telephone poles along a street.
As a consequence of this the cable-feet distance may be much greater than the straight line distance.
As an example, DSL Internet service is sensitive to distance. The more cable feet between your house and the telephone company central office, the slower the maximum obtainable speed, and beyond some distance the service is not available. You might be two miles line of sight from a central office but the cable might take a route that is five miles long to get there. That would be an extreme example but things like this can happen because of natural obstacles such as canyons or lakes.
