AIR BLOW FIBER LINE AND ITS CONNECTOR

摘要

PURPOSE:To provide the air blown fiber line for limiting water intrusion within the section even in the case water is intruded into a tube due to an unexpected cable disconnection accident, etc., and its connector. CONSTITUTION:In the air blown fiber line for constituting an optical fiber unit 1 by feeding forcibly air into a tube 2, the air blown fiber line and its connector are constituted so that the inside diameter of a part in the lengthwise direction of the tube 2 is varied reversibly from a state of the time of forcible feeding to the optical fiber unit to a state of coming into soft contact with the outside peripheral surface of the optical fiber unit 1 subjected to forcible feeding, and water running between the tube 2 and the optical fiber unit 1 is prevented.
