    摘要： In an embodiment of the present invention, provided is an optical fiber including a glass core, and a polymer cladding formed around the glass core, the polymer cladding containing a mixture of a polymerizable composition and a silane coupling agent, and a fluorine-based ultraviolet curable resin. The mixture contains 5 to 95 parts by weight of the silane coupling agent based on 100 parts by weight of the total weight of the mixture. The fluorine-based ultraviolet curable resin alone has a refractive index in a range of 1.350 to 1.420 after ultraviolet curing. A component originated from the silane coupling agent is concentrated within a range of 20 µm or less in the polymer cladding from an interface between the glass core and the polymer cladding.

    摘要： A fiber optic cable includes a first optical fiber, a jacket, and a second optical fiber. The first optical fiber includes a glass core and cladding. The glass core is configured to provide controlled transmission of light through the fiber optic cable for high-speed data communication. The jacket has an interior surface that defines a conduit through which the first optical fiber extends. The jacket further has an exterior surface that defines the outside of the fiber optic cable. The second optical fiber is integrated with the exterior surface of the jacket.

    摘要： The specification describes an optical fiber color coding scheme that uses two colors (see 13a,13b), where each of the two colors constitutes one half of the surface of the optical fiber coating. If a longitudinal portion of the coating is considered a hollow cylinder, then each of the two colors is a hollow hemi-cylinder. To ensure that each of the two colors is always plainly visible to an installer, the two colors are formed with a twist. Using two colors for coding substantially increases the number of available unique color codes. Coloring the entire coating reduces the chances of error in identifying the optical fibers.

    摘要翻译： 本说明书描述了使用两种颜色（见13a，13b）的光纤颜色编码方案，其中两种颜色中的每一种构成光纤涂层表面的一半。 如果涂层的纵向部分被认为是中空圆筒，则两种颜色中的每一种都是中空半圆柱体。 为了确保两种颜色中的每一种总是对于安装者来说是清晰可见的，这两种颜色形成一个扭曲。 使用两种颜色进行编码大大增加了可用唯一颜色代码的数量。 着色整个涂层会降低识别光纤的错误机会。
