Double-window fiber, also known as dual-window fiber, is a type of fiber optic cable designed specifically to support two different wavelengths of light. It is commonly used in applications such as communication networks, video transmission, and data transfer, as well as in sensing and monitoring equipment.
Multimode double-window fiber is optimized for 850 nm and 1300 nm operation, while single-mode double-window fiber is optimized for 1310 nm and 1550 nm operation. The two windows, or wavelengths, of light, travel through the fiber separately, allowing for two different signals to be transmitted through the same cable. This is especially useful in applications where two separate data streams need to be carried out simultaneously.
The double-window fiber cable consists of a glass core and a cladding, both of which are made of highly pure, low-loss materials. The glass core is designed to maximize the transmission of light, while the cladding is designed to minimize the amount of light that is reflected back. The fiber cable also has a protective coating, which helps to protect it from environmental elements such as dirt and moisture.
Double-window fiber is extremely reliable, with very low rates of signal attenuation and distortion. It is also relatively lightweight and flexible, making it easy to install and maintain. Additionally, it can be used with most existing fiber optic equipment, making it a cost-effective solution for many types of applications.
Overall, double-window fiber is an excellent choice for applications that require the transmission of two different signals over a single fiber cable. It is reliable, lightweight, and flexible, and can be used with a variety of existing fiber optic equipment.
