Groove cable

A cable system, comprising:

• 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;
• and
• a pavement including a groove extending vertically into but not through the pavement, wherein said cable is provided within said groove, wherein said cable has a linear expansion due to a change in temperature from 20° C. to 70° C. with respect to an 800 ft. run length of less than 0.7 ft.

A cable system, comprising:

• 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;
• and
• a pavement including a groove extending vertically into but not through the pavement, wherein said cable is provided within said groove, wherein the at least one buffer tubes is made of a polybutylene terephthalate material and wherein the polybutylene terephthalate material is hydrolytically stabilized to maintain ultimate strains of greater than 100 percent after aging 30 days at 85° C. and 85% RH and greater than 10 percent after aging 45 days at 85° C. and 85% RH.
