Patent ID: 7529451

Claim:
A fiber optic cable comprising: at least one optical fiber ribbon; a first dry insert, the at least one dry insert having a first thickness at a first longitudinal location and a second thickness at a second longitudinal location, wherein the first thickness is greater for the second thickness, thereby creating a thickness variation along the longitudinal length of the at least one dry insert; a second dry insert, wherein the at least one optical fiber ribbon is disposed between the first dry insert and the second dry insert; and a cable jacket, the cable jacket having at least one cavity, wherein the at least one optical fiber and at least one dry insert are disposed within the at least one cavity, wherein the at least one dry insert couples the at least one optical fiber to the cable jacket, wherein the first dry insert has a dry insert thickness ratio, the first dry insert thickness ratio being defined as the second thickness divided by the first thickness, wherein the dry insert thickness ratio (T 2 /T 1 ) is between about 50% and about 90%.
