Abstract:
A device for feeding optical fibers into a tubular element, comprising:a compressed air-operated feeder in which an optical fiber is advanced with the aid of compressed air delivered via one or more openings to a rear portion of a passage in the feeder, in which the optical fiber is located, wherein said compressed air is evacuated via one or more openings in a forward portion of said passage; and a bar which can be removably inserted into and fixed in the passage, the bar having at least one groove formed in the length of the bar; the groove, in conjunction with a surface of said passage, forming a blow passage having a cross-sectional shape that is adapted to a specific cross-section of optical fiber, such that said specific optical fibers having mutually different cross-sections can be fed into the tubular element with the aid of the same optical fiber feeding device by adjusting the spacing between the bar surface with the groove and the surface of said passage.
