Abstract

An optical tube assembly (10) having at least one optical waveguide (12), at least one dry insert (14), and a tube (18). In one embodiment, the dry insert (14) has a first layer (14a) and a second layer (14b). The first layer is a polyurethane foam and the second layer is a water-swellable layer, wherein the dry insert is disposed within the tube (18) and generally surrounds the at least one optical waveguide (12).
