Permeance properties of a stalpeth sheath and a laminated aluminum polyethylene (LAP) sheath are analyzed experimentally. From a view point of the permeance property, the LAP sheath which is coated with adhesive copolymer on both sides on an aluminum tape is available for 2.6/9.5 mm coaxial cable whose sheath has been extruded lead sheath yet.

The thin coated fiber design against lateral force is discussed and a 0.5 mm diameter Polyetherimido coated optical fiber which has equivalent optical loss increase properties against lateral force to conventional 0.9 mm diameter Nylon coated optical fibers is proposed. The method of calculating critical lateral force which causes loss increase is shown. Using the result, it is possible to design coated optical fibers having no loss increase at a given lateral force.
