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&#xb0; C. to 70&#xb0; C. of less than 305 lbs when constrained.

Groove cable

A buffer tube design that allows easy access to signal carrying fibers disposed within the buffer tube with risk of damaging the signal carrying fibers. The buffer tube can be made with a ripcord disposed within. Additionally, the buffer tube has the mechanical properties that allow the ripcord to be pulled through the tube wall with less energy than is required to bend the signal carrying fibers within. The buffer tube can also be designed without a ripcord in such a way that the mechanical properties allow the tube to be hand torn using a lower amount of energy than required to bend the signal carrying fibers within.

Buffer tube that results in easy access to and low attenuation of fibers disposed within buffer tube
