Telephone Cables

pre 1945

The Bell Telephone System expects to have 2,000 miles of its coaxial cable network manufactured and at least three-fourths of this mileage in the ground by the end of 1945.

The rapid rate at which the job is going forward has been dictated by the steadily increasing need for more telephone circuits between the nation’s principle war centers.

Besides its telephone use, coaxial cable can be equipped to carry television programs.

Above is a fanned-out view of the six-coaxial cable, showing the construction of its various conductors.

Aside from the coaxials themselves, the cable contains a number of regular telephone wires which provide additional long distance circuits.
