More Information
Summary:An optical fibre member is disclosed which includes a compound sheath having an inner sheath of high modulus and density, and an outer sheath layer of low density material having a lower modulus. The outer sheath layer may be of foamed polyethylene and the inner sheath of polypropylene, both conveniently formed by extrusion. The optical fibre members are especially suited for installation in transmission lines by gas flow propulsion.
