Abstract:
An optical fiber unit employed in a submarine optical cable, said optical fiber unit comprising:a plastic support extending along a predetermined axis, said plastic support including a space extending along said axis; one or more coated optical fibers accommodated within said space; a resin filling a gap between an inner wall face of said plastic support defining said space and said coated optical fibers, said resin having such a viscosity that said coated optical fibers are radially movable therein; and one or more rigid compression members embedded along said space in a plastic region between said inner wall face of said plastic support and an outer wall face of said plastic support defining an outer shape of said plastic support, wherein an outline of said space, defined by a cross-section of said plastic support, has a non-circular shape and is different from that of said plastic support; and wherein, in said cross-section of said plastic support, a minimum width of said space is greater than a maximum width of each of said rigid compression members.
