A Fiber Optic Distribution Hub (FDH) is a device used in fiber optic communication networks to distribute optical signals from a single feeder fiber to multiple distribution fibers. It is typically located in a central office or at the edge of the network, and serves as a point of interconnection between the backbone network and the distribution network.
The FDH consists of several components, including a splice tray for splicing feeder and distribution fibers, a splitter module for splitting the optical signal, and a distribution module for connecting the distribution fibers. The splitter module splits the optical signal into multiple outputs, allowing the signal to be distributed to multiple subscribers or nodes.
FDHs are used in a variety of applications, including fiber to the home (FTTH) and fiber to the curb (FTTC) networks, where they provide a convenient and efficient way to distribute optical signals to multiple locations. They are also used in cable TV networks and in the telecommunications industry.
Overall, the use of fiber optic distribution hubs enables efficient and reliable distribution of optical signals, and helps to ensure high-quality communication networks that can meet the demands of modern communication applications.
