Abstract: A hybrid method of making silica-based optical fiber comprises providing a VAD-produced core rod and collapsing a substrate tube comprising an MCVD-produced cladding onto the core rod. Optically inactive cladding material (of the substrate tube) provides the bulk of the optical fiber. The hybrid process takes advantage of VAD's ability to rapidly produce a core rod of substantial size, and also takes advantage of MCVD's ability to form in a substrate tube a deposit having relatively complex refractive index profile. The hybrid method can result in lower production cost.

Abstract: The specification describes a process and apparatus for monitoring and controlling the ellipticity of preform tubes during Modified Chemical Vapor Deposition. In response to computer generated signals from the monitoring device, the tube collapse rate is adjusted dynamically by locally changing the temperature of the glass tube, or by changing the physical force acting to collapse the tube.

Abstract: Embodiments of the invention include a positive dispersion optical fiber (50, 55) that includes a doped core region (51, 56) with an index of refraction n 1 , a cladding region (54, 59) with an index of refraction n 2 , and first (52, 57) and second (53, 58) annular rings or regions therebetween with indices of refraction n 3 and n 4 , respectively. The various regions are manufactured in such a way that the refractive index value ranges are: 0.14 1 -n 2 )/n 2 3 -n 2 )/n 2 4 -n 2 )/n 2 2 -km) at a wavelength of 1550 nm. Also, the fibers have a relatively large effective core area, A eff , for example, greater than 100.0 µm 2 , and a relative dispersion slope (RDS) less than 0.0032 nm -1 . The mode field diameter (MFD) is at least 11.9 ± 0.7 µm. These desirable transmission characteristics are achieved without many of the manufacturing and economic limitations of conventional fibers.

Abstract: The specification describes a process and apparatus (not claimed) for collapsing preform tubes in Modified Chemical Vapor Deposition processes. The problem of bubble formation during tube collapse was found to be attributable to excess dopant vapor pressure emitted from the hot zone during the final stage of tube collapse. This excess pressure is controlled by cooling (via means 63) the tube (61) in advance of the torch (62), thereby decreasing the viscosity of the dopant vapor and increasing its transport rate. This is found to reduce internal tube pressure and eliminate bubble formation in the collapsed preform.

Abstract: The deposition rate of MCVD processes is enhanced by applying to the outside of the deposition tube (101) at least a first (107) and a second (103) independently controlled heat source to a plurality of reactant vapours flowing in the tube which are used to form deposited particulate matter on the inside of the tube (101). The first heat source (107) is adjusted so as to provide at least a specified rate of reaction for the reactants, and the second source (103) is adjusted so as to provide at least a specified deposition rate on the inside of the tube (101) for the particulate matter formed by the chemical vapour reaction.
