Abstract
A fiber optic cable can inhibit water that may inadvertently enter the cable from flowing lengthwise within the cable. The fiber optic cable can include a buffer tube defining an interior volume extending along the cable. Water blocking barriers can be disposed in the buffer tube intermittently along the length of the cable. The barriers can be formed from a UV and thermal cured material and can comprise an acrylic. The barriers can be applied to the optical fibers or to a carrier tape that is wrapped around the optical fibers or fiber bundle. The barriers (or carrier tape) can be disposed against and/or adhere to an inner surface of the buffer tube to provide intermittent water blocking. Each barrier can provide a seal around the optical fibers and can limit flow of water in the interior volume.
