In fiber optic cable manufacturing, black and white colored fibers are commonly used. While both colors serve the same purpose of transmitting light signals, there are some differences between the two. In this article, we will discuss the difference between black and white fibers in fiber optic cable.
Appearance:
The most obvious difference between black and white fibers is their appearance. As the name suggests, black fibers are black in color, while white fibers are white. The color of the fiber is determined by the type of coating that is applied to the fiber during manufacturing.
Fiber type:
Black fibers are usually made from single-mode fiber, which has a smaller core diameter than multi-mode fiber. Single-mode fiber is designed to transmit light over long distances with minimal signal loss. White fibers, on the other hand, are typically made from multi-mode fiber, which has a larger core diameter and is designed for shorter distance transmissions.
Application:
Black fibers are commonly used in long-distance fiber optic networks, such as telecommunications and data center applications. White fibers are more commonly used in short-distance applications, such as within a building or campus network.
Signal strength:
Black fibers have a higher signal strength than white fibers, due to their smaller core diameter. This means that black fibers can transmit light over longer distances without the need for amplification. White fibers, on the other hand, have a lower signal strength and require amplification for long-distance transmissions.
Cost:
The cost of black and white fibers can vary depending on the manufacturer and the application. Black fibers tend to be more expensive than white fibers, due to their higher signal strength and use in long-distance applications.
Compatibility:
Black and white fibers are compatible with each other, and can be used together in the same fiber optic cable. However, it is important to ensure that the fibers are properly paired with the correct equipment and connectors to ensure optimal performance.
In conclusion, black and white fibers are both used in fiber optic cable manufacturing, but are designed for different applications. Black fibers are typically used in long-distance applications, while white fibers are used in short-distance applications. Black fibers have a higher signal strength and are more expensive, while white fibers have a lower signal strength and are less expensive. Both fibers are compatible with each other, but it is important to ensure proper pairing with equipment and connectors for optimal performance.
