Abstract: A fiber optic cable having both water blocking and flame retardant properties that is particularly useful for indoor or indoor/outdoor applications. In one embodiment, the fiber optic cable includes at least one buffer tube, at least one optical fiber disposed within the buffer tube, a composite tape surrounding the buffer tube that comprises a layer formed of an inherently flame retardant material and at least one coating a water swellable material, and a jacket surrounding the composite tape. The fiber optic cable can also include a water blocking element disposed within the buffer tube. The water swellable coatings of the composite tape and the water blocking element within the buffer tube therefore inhibit water migration along the length of the cable, while the flame retardant layer of the composite tape provides fire resistance.
