FTTP MDU Solutions Low Rise/Garden and the Horizontal Style For the design of some properties, a Fiber Distribution Hub (FDH) may be placed in strategic locations depending on the number of living units. The FDH has a feeder cable from the street Right of Way and a distribution cable that feeds the complex. 18
FTTP MDU Solutions OSP Access Pull Boxes The distribution cables terminate in pull boxes throughout the property. The larger capacity cables are spliced into smaller cables that feed directly into specific buildings. The pull boxes are utilized instead of above ground pedestals to maintain aesthetics. 19
