    摘要: An optical fiber production method includes: drawing an optical fiber from an optical fiber preform; and cooling the optical fiber. When in the cooling process, the optical fiber is passed through a plurality of annealing furnaces and Equation (1) is held. A time constant of relaxation of a structure of glass forming a core in the optical fiber is τ(Tn). A temperature of the optical fiber at a point in time when the optical fiber is delivered into an nth annealing furnace from an upstream side is Tn. A fictive temperature of glass forming the core at the point in time when the optical fiber is delivered is Tfn. A fictive temperature of glass forming the core after a lapse of time Δt from the point in time when the optical fiber is delivered is Tf. 20° C.

    摘要: Apparatus, systems and methods for monitoring and controlling the amount of moisture introduced into the forming hood area in the manufacture of mineral fiber insulation products. Moisture from coolant liquids, binder dispersions and binder diluents are all introduced deliberately into a forming hood; ambient moisture and water from combustion are additional sources. A series of global variable control valves, one for each fluid system; as well as individual variable control valves for each fiberizing unit are provided with associated meters. Sensors monitor fibrous pack conditions and ambient conditions and provide inputs to the valve control system. A specific 3-ring liquid dispensing system is also disclosed.

The first cooling tube includes a plurality of cooling fluid outlets positioned along an axial length of the first cooling tube which are oriented to direct a flow of cooling fluid across the optical fiber pathway towards the second cooling tube. The second cooling tube includes a plurality of cooling fluid outlets positioned along an axial length of the second cooling tube which are oriented to direct a flow of cooling fluid across the optical fiber pathway towards the first cooling tube.

    摘要: There is described herein a method and system for inscribing gratings in optical waveguides. The waveguides may be hydrogen-free, germanium-free, low germanium, low hydrogen, and a combination thereof. Such gratings written in hydrogen-free fibers are suitable for sensor applications in which the use of hydrogen for photosensitizing fibers is undesirable owing to their increased sensitivity to nuclear radiation. The grating are formed by at least one pulse having a wavelength comprised between about 203 nm and about 240 nm. The laser source may be a Continuous Wave (CW) laser source or a pulsed laser source generating at least one pulse having a width in the order of nanoseconds (109).
