Non-Dispersion Shifted Fiber (NDSF) is a type of single-mode fiber that is designed to eliminate the need for dispersion compensation in long-haul fiber optic applications. It is the most popular type of fiber currently deployed due to its low cost and flexibility.
NDSF is designed to have a zero-dispersion wavelength (ZDW) near 1310 nm, which is the most commonly used wavelength in telecommunications. This allows for the transmission of more data over longer distances without the need for additional dispersion compensation. This is beneficial for applications that require large amounts of data to be transmitted over long distances, such as in cable and satellite communications, as well as for internet service providers.
NDSF is also popular because of its small diameter and lightweight, which makes it easier to install and manage. Additionally, it is resistant to corrosion and other environmental factors, making it a great choice for outdoor applications.
Overall, NDSF is a great choice for cable and satellite communications, as well as for internet service providers. Its ability to transmit more data over longer distances without the need for additional dispersion compensation makes it highly efficient and cost-effective. Additionally, its small diameter, lightweight, and resistance to environmental factors make it a great choice for outdoor applications.
