    Abstract: A system for processing an optical fiber includes: a draw furnace, the draw furnace containing an optical fiber preform; a bare optical fiber drawn from the optical fiber preform, the bare optical fiber extending from the draw furnace along a process pathway; and a slow cooling device operatively coupled to and downstream from the draw furnace, the slow cooling device exposing the bare optical fiber to a slow cooling device process temperature in the range form 1000° C. to 1400° C., wherein the bare optical fiber passes through the slow cooling device at least two times.

    Abstract: In some embodiments, an optical fiber transmission link, includes a length of dispersion compensating fiber (DCF), the dispersion compensating fiber coupled to a length of single-mode fiber (SMF) having a zero dispersion wavelength of 1300 nm to 1324 nm; wherein the optical fiber transmission link comprising the dispersion compensating fiber coupled to the single-mode fiber and operating at wavelengths between 1265 nm and 1375 nm increases maximum link lengths of the optical fiber transmission link by more than 60% as compared to the link length of the optical fiber transmission link with the single-mode fiber only; and wherein the maximum link length is calculated from the maximum allowed positive and negative accumulated dispersion at wavelengths between 1265 nm and 1375 nm.

    Abstract: A plugged honeycomb structure includes intersecting porous walls extending in an axial direction between an inlet end and an outlet end of the honeycomb structure, the intersecting porous walls forming a matrix of repeating unit cells arranged in a repeating pattern. The repeating unit cells comprise: three or four channels, each channel formed by four walls, wherein the three or four channels comprise more inlet channels than outlet channels, at least one wall of an inlet channel or an outlet channel is intersected midwall by a wall, an area of an outlet channel is equal to or less than an area of any of the inlet channels, and continuous line segments extending along walls of at least three repeating unit cells. Other plugged honeycomb structures, plugged honeycomb bodies, honeycomb extrusion dies, and methods are disclosed.

    Abstract: Preparation of halogen-doped silica is described. The preparation includes doping silica with high halogen concentration and sintering halogen-doped silica to a closed-pore state in a gas-phase environment that has a low partial pressure of impermeable gases. Impermeable gases are difficult to remove from halogen-doped fiber preforms and lead to defects in optical fibers drawn from the preforms. A low partial pressure of impermeable gases in the sintering environment leads to a low concentration of impermeable gases and a low density of gas-phase voids in densified halogen-doped silica. Preforms with fewer defects result.
