For which type of network is Multimode Graded-Index fiber typically used?

Multimode Graded-Index fiber is commonly used in Local Area Networks (LANs) for various applications, including fiber to the desk deployments. This type of fiber is designed to manage light transmission effectively over short distances, which is a key requirement in typical LAN environments where the distances between the server and the user’s desktop are relatively short, often not exceeding 300 meters.

The grading in the refractive index of the fiber allows for the reduction of modal dispersion, thereby improving the signal quality over these distances compared to standard multimode fiber. This characteristic makes it particularly well-suited for high-speed data transfer within an office or campus environment, thus fostering better performance for applications such as data, voice, and video traffic.

In contrast, other network types such as Telecom outside plant, Consumer digital audio, and CATV hybrid fiber coax networks utilize different fiber types and configurations that cater to their specific performance needs and operational environments. For instance, outside plant applications often require single-mode fiber for long-distance communications due to its lower attenuation and longer reach capabilities.
