Abstract
A device for feeding optical fibers into a tubular element, duct, or the like. For ease of handling, the fiber feeding device includes a channel into which there can be inserted a bar which includes one or more longitudinally extending blow passages, where each passage has a cross-section that is adapted to a given type of optical fiber. Holes are provided in the bottom surface of the channel close to its respective rear and front edges, for delivering and removing compressed air used to advance the optical fiber. With the optical fiber placed in the blow passage in the bar, the optical fiber in said passage will be advanced when compressed air is delivered through the holes in the rear edge of the bar, by virtue of the blow passage functioning as a Venturi tube where a leakage flow exerts an ejector effect on the optical fiber to promote advancement of said fiber through the blow passage.
