Triple-Play Service Deployment

From the splice enclosure, signals are transmitted along the
complete feeder to the fiber distribution hub (FDH), where the
signal distribution occurs through the use of passive optical
splitters. Thirty-two branches per splitter and 10 splitters per FDH
are typically the maximum split levels implemented. To
accommodate this, the FDH houses multiple splitters as well as
splicing trays and connectors. No power is required at this location
because all of the components are passive components. This hub
is also called the primary flexibility point (PFP) or the fiber cross
connect (FCC). If different splitters exist along the cable, then the
other splitters are located at a fiber distribution panel (FDP).

Chapter 3: Deploying and Troubleshooting Fiber Networks
After the FDH in the network, one fiber in the distribution cable is
earmarked per customer. When a customer is designated, the
splitter is connected to the fiber of this specific customer. Before a
customer is designated, the fibers coming from the distribution
cable and from the splitters are left open. They are positioned,
unconnected, in a ‘parking lot.’ The term “parking lot” defines a
staging or waiting area for connectors. In order to satisfy the
constraints of the ORL, APC connectors are used here.
