Fiber optic cable sheaths can come in various colors, and the specific color coding can vary depending on the industry, application, and regional standards. While there is no universal color code for fiber optic cable sheaths, the following color conventions are commonly used:
Single-Mode Fiber: Single-mode fiber optic cables, which are designed for long-distance transmission, often have a yellow sheath. However, in some cases, they may also be designated with other colors such as blue or white.
Multimode Fiber: Multimode fiber optic cables, used for shorter distance transmission, typically have an orange sheath. However, similar to single-mode fiber, other colors like aqua or gray might be used in certain situations.
Indoor Applications: Fiber optic cables for indoor use, such as within buildings or data centers, often have a gray or black sheath. This helps differentiate them from outdoor cables and is commonly used for patch cords and interconnect cables.
Outdoor Applications: Fiber optic cables intended for outdoor installations often have a black sheath. The black color provides UV protection and helps the cables blend in with the surroundings.
It is important to note that these color conventions are not universally standardized, and there may be variations or exceptions depending on specific applications, manufacturers, or local practices. In any case, it is recommended to consult the cable manufacturer or adhere to applicable industry standards or regional guidelines for accurate identification of fiber optic cable sheath colors.
