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。

摘要： A bend insensitive fiber optic cable includes a singlemode fiber, a buffer layer surrounding the fiber wherein a thickest component of the buffer layer has an elastic modulus greater than 515 MPa (75,000 psi), and a jacket surrounding the buffer layer, wherein the jacket has a thickness of at least 1.2 mm. In one preferred embodiment, the buffer layer includes a nylon 12 resin with a nominal elastic modulus of approximately 218,000 psi. In this embodiment, an inner thin component of the buffer layer is made of an ethylene/ethyl acrylate resin so as to facilitate stripping of the buffer layer away from the fiber.

摘要： A bend insensitive fiber optic cable (10) includes a singlemode fiber (12), a buffer layer (14) surrounding the fiber (12) wherein a thickest component of the buffer layer (14) has an elastic modulus greater than 515 MPa, and a jacket (18) surrounding the buffer layer (14), wherein the jacket (18) has a thickness of at least 1.2 mm. In one preferred embodiment, the buffer layer (14) includes a nylon 12 resin with a nominal elastic modulus of approximately 1497 MPa. In this embodiment, an inner thin component of the buffer layer (14) is made of an ethylene/ethyl acrylate resin so as to facilitate stripping of the buffer layer (14) away from the fiber (12).
