Detailed analysis of ADSS cable color

　　ADSS (All Dielectric) The color of Self-supporting (all-medium self-supporting) fiber optic cables, especially the color of their internal fibers, usually follows a certain chromatographic arrangement. These chromatographic arrangements not only help in the identification of fiber optic cables during manufacturing and installation, but also facilitate subsequent maintenance and troubleshooting. The following is a detailed analysis of the color of ADSS fiber optic cables:

　　First, optical fiber chromatography

　　The fibers inside the ADSS cable are usually arranged according to a certain color spectrum, which includes blue, orange (orange), green, brown, gray, white and other colors. The specific arrangement may vary depending on the number of cores in the cable. For example:

　　2 to 24 core specifications: 4 cores per tube, the order of chromatography may be blue, orange, green, brown (or other colors such as gray and white as spare or specific uses).

　　2 to 36 core specifications: 6 cores per tube, the sequence of chromatography will be adjusted to accommodate more fiber optics.

　　2 to 48 core specifications: 8 cores per tube, also following a specific chromatographic arrangement.

　　It is important to note that different manufacturers or batches of fiber optic cables may have slightly different color spectra. Therefore, during installation and maintenance, refer to the specific cable specification or the information provided by the manufacturer.

　　Second, the color of the cable jacket

　　The jacket of ADSS cable is usually made of materials such as black polyethylene (PE), which has good weather and wear resistance and can protect the cable from bad weather and mechanical damage. The black jacket is not only concealed, but also helps to reduce UV exposure, thus prolonging the service life of the cable.

　　III. The relationship between color and function

　　In ADSS cables, different colors of fiber may represent different functions or uses. For example:

　　Single-mode fiber optic cable: Colors such as blue and orange are usually used to identify different fibers.

　　Multimode fiber optic cables may be distinguished by colors such as green and brown.

　　Spare fiber: may be identified in gray, white, or other specific colors.

　　In addition, with the development of technology and the increase in application requirements, some special color fibers are also used to achieve specific functions, such as purple, pink, and cyan fibers used in wavelength division multiplexing (WDM) technology.

　　In summary, the color of ADSS fiber optic cable not only has the effect of beauty and concealment, but more importantly, it helps to identify and distinguish during the manufacture, installation, maintenance and troubleshooting of fiber optic cable. Therefore, when using ADSS fiber optic cable, it should be fully understood its color law and meaning to ensure the normal operation and long-term use of fiber optic cable.
