The IFDB-M is an enclosure to break out fibers from an indoor riser cable into individual drops to the living units of an MDU. These drops provide a fiber optic connection to the living units.
The IFDB-M allows to break out fiber from certain riser cables by making a window cut not larger than 70 mm without interrupting the strength member.
To connect the drop to the raiser fibers splices or Xpres-drop connectors can be used.
