This paper describes a special set-up which principle of operation bases on elongation procedure of fiber-optics in a low-pressure gas burner. The universal construction of set-up makes it possible to prepare different elements from any kind of optical fibers, including single-mode, multi-mode and polarization maintaining as well as optical fiber with different indices distribution and operation wavelengths. The basic element is fiber-optic biconical taper (diameter about several um on length up to 10 -15 mm), which due to a small cross-section enables achievement of optical beam propagation outside the fiber in direct way. The paper presents the overview of different elements, which structure is based on above taper, such as: X-type in-line fiber-optic couplers operating in a wide range of wavelengths, in-line optical polarizers as well as polarization switchers. An important thing about these elements is a possibility to operate in the wavelength different from the classical telecommunication range.
