Method of inserting a light transmitting member into a tube

摘要

A method of inserting an unreinforced fiber optic member into a duct is disclosed. An elongate, flexible pull cord is inserted into the duct and is attached adjacent its rearward end to the fiber optic member adjacent a forward end thereof. The forward end of the fiber optic member is then introduced into the duct, and fluid such as air is caused to flow along the duct to cause the pull cord and fiber optic member to move into the duct.
