AIR BLOWN FIBER OPTIC CABLE

摘要

The present invention relates to an air pressure laying optical cable and comprises; an optical fiber; a loose tube which surrounds the optical fiber and forms a filling space in a gap with the optical fiber and is made of polycarbonate; a waterproof filter which is filled in the filling space within the loose tube; an external jacket which is coated on the outer side of the loose tube. The air pressure laying optical cable suppresses the twist of the optical fiber accepted in the inner side by the loose tube made of the polycarbonate and performs long distance paving by air pressure with a low friction factor of the external jacket made of a nylon material and suppresses the breakage by a white ant.
