The fiber unit is covered with a plastic or steel tape, and the whole surrounded with aluminum and steel strands. Individual fibers may be in "loose buffer" tubes, where the inside diameter of the tube is greater than the fiber outside diameter, or may be "tight buffered" where the plastic buffer is coated directly on to the glass.
An eight-way optical signal splitter to feed eight virtual LNBs or further splitters from a single optical feed. While optical fibre has been used for telephone and Internet backbone data, and even for television and multimedia carriage for terrestrial cable, for many years, use for satellite IF distribution has been held back by considerations of cost and installation convenience.
