    • Embodiments of the invention include a method and apparatus for making optical fiber preforms and optical fiber. The method includes the steps of positioning an overclad tube around a preform core rod, heating the overclad tube along the length thereof in the presence of a pressure gradient to collapse onto the preform core to form the overclad optical fiber preform, and adjusting the radial size of a heated portion of the preform core rod and/or the overclad tube to actively match the radial dimensions of the preform core rod along the length thereof with corresponding portions of the overclad tube. The active matching reduces variations in the physical dimensions of the preform core rod and/or the overclad tube, which improves transmission and other performance characteristics of fiber drawn from the created preform, e.g., by maintaining a relatively constant D/d ratio of the preform.

    • A microporous structure can be formed from ductile material such as glass into an axially extended outer wall surrounding a plurality of singular micro-passages surrounded by the outer wall to provide an open area that extends continuously over the length of the outer wall. The diameter of the micro-passages will usually not exceed 25 &mgr;m and are more in range of from 0.5 to 5 &mgr;m. The structure is particularly useful as frits for the containment of packing in capillaries for chromatograph applications and more generally as flow restrictors. Continuous open diameters of the micro-passages have a relatively straight flow path that reduces pressure drop relative to the random arrangement of other frits while still providing the desired containment.
    • 微孔结构可以由诸如玻璃的延性材料形成为围绕由外壁包围的多个奇异微通道的轴向延伸的外壁,以提供在外壁的长度上连续延伸的开放区域。 微通道的直径通常不超过25μm,并且更多在0.5至5μm的范围内。 该结构特别可用作用于容纳用于色谱仪应用的毛细管中的填料的玻璃料,更通常地作为限流器。 微通道的连续开放直径具有相对直的流动路径,其相对于其它玻璃料的随机排列减小压降,同时仍然提供期望的密封。
