What is the primary function of the Fiber Distribution Hub (FDH)?

The primary function of the Fiber Distribution Hub (FDH) is to manage and group splitters into local serving areas. This is essential in fiber optic networks as it allows for the efficient distribution of optical signals from the main fiber lines to various local areas that are being served.

The grouping of splitters in the FDH helps optimize the performance of the network by allowing a more organized and logical distribution process, making it easier to manage the signal strength and quality over different neighborhoods or regions. By segmenting the splitters in this manner, the system can efficiently connect multiple customers to the fiber optic backbone while minimizing signal loss and maintaining overall network robustness.

In contrast, while FDHs can indeed serve a variety of functions related to fiber networks, such as providing connection points for customer premises or serving as a demarcation point, these are not their primary roles. The primary focus on managing splitters demonstrates their importance in local area network design and operation.
