摘要： The present invention relates to a reduced-diameter optical fiber that employs a novel coating system. When combined with a bend-insensitive glass fiber, the novel coating system according to the present invention yields an optical fiber having exceptionally low losses. The coating system features (i) a softer primary coating with excellent low- temperature characteristics to protect against microbending in any environment and in the toughest physical situations and, optionally, (ii) a colored secondary coating possessing enhanced color strength and vividness. The secondary coating provides improved ribbon characteristics for structures that are robust, yet easily entered (i.e., separated and stripped). The optional dual coating is specifically balanced for superior heat stripping in fiber ribbons, with virtually no residue left behind on the glass. This facilitates fast splicing and terminations. The improved coating system provides optical fibers that offer significant advantages for deployment in most, if not all, f?ber-to-the-premises (FTTx) systems.
摘要翻译：本发明涉及采用新型涂布系统的直径缩小的光纤。当与弯曲不敏感的玻璃纤维结合时，根据本发明的新型涂层系统产生具有极低损耗的光纤。涂层系统的特征是（i）具有优异的低温特性的较软的初级涂层，以防止任何环境和最强的物理情况下的微弯曲，以及（ii）具有增强的颜色强度和鲜艳度的着色的二次涂层。二次涂层为结构提供了改进的带状特征，该结构坚固且容易地进入（即分离和剥离）。可选的双涂层是特别平衡的，用于在纤维带中实现优异的热剥离，玻璃上几乎没有留下残留物。这有助于快速接合和终止。改进的涂层系统提供光纤，其在大多数（如果不是全部）的基站（FTTx）系统中的部署提供显着的优点。

摘要： A buffered optical fiber arrangement that includes a buffer tube in which is provided optical fibers and a texturized yarn coated with a water-swellable material. The filament diameter of the yarn used in the present invention may be between about 5 microns and about 100 microns, more preferably between about 10 and about 60 microns, still more preferably between about 20 and about 40 microns. The linear density, or denier in grams per 9000 meters, of the base yarn may be between about 100 and 1000, more preferably between about 200 and 600, or still more preferably between about 250 and 350. The degree of decrease in length (the "degree of texturizing") between the perfectly straight filaments before texturizing and the texturized filament may be between 1 percent and 90 percent, more preferably between about 2 percent and 50 percent, or still more preferably between about 5 percent and 25 percent.
