ABSTRACT:
A cable system and method including a cable or a microduct provided within the groove extending vertically into, but not through, a pavement. The cable has a central strength member, at least one buffer tube stranded around the central strength member, an outerjacket surrounding the buffer tube and central strength member, and at least one transmission element provided within said at least one buffer tube. Provided within the microduct is a microduct cable including at least one transmission element. A cable including a central strength member, at least one buffer tube stranded around the central strength member, an outer jacket surrounding the buffer tube and central strength member, and at least one transmission element provided within said at least one buffer tube. The cable has a longitudinal thermal expansion force due to a change in temperature from 20° C. to 70° C. of less than 305 lbs when constrained.
