• 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.

• 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.

MDU Reduced Bend Radius Fiber

• Innovations in “Reduced

Bend Radius” fiber will ease bend radius challenges

• Ease of installation for technicians.

Indoor Drop Cables RealFlex™

FTTP MDU Product Solutions –

Radius Drop Cables

• Med or high-rise; RBR can be used to transfer from an indoor fiber distribution terminal to each individual living unit within a building

• Garden or horizontal;

indoor/outdoor cable used to transition from an outdoor fiber distribution terminal to each indoor living unit

• Greatly reduces risk to bend induced insertion loss created during installation

• Indoor/outdoor and riser cables are suitable for all OFNR

applications; OFNP applications will require plenum cable

FTTP MDU Product Solutions –

Radius Drop Cables

• Bend radius as small as 7.5 mm without

changing cable characteristics

• Greatly reduces risk to bend induced

insertion loss created during installation

• Rugged 5.0mm indoor/outdoor cable

jacket is composed of Low-Smoke Zero-Halogen rated materials and incorporates water swellable yarns
