1 PRODUCT DESCRIPTION

1.1 General Description

The Rapid Flexible Fiber Box (FFB), shown on the cover of this user manual, is a rugged, weather-resistant demarcation and aggregation box equipped with an internal RapidReel cable spool for easy storage, unreeling, and installation of a feeder cable spooled within the product. The feeder cable may be either stub-ended or terminated with an MPO connector. Cable length is either 100 feet for a 24-fiber cable or 200 feet for a 12-fiber cable.
The Rapid FFB is used in Fiber-to-the-Cell-Site (FTTCS) and Fiber-to-the-Antenna (FTTA) applications. In a typical installation, the Rapid FFB is mounted on a utility pole or wall at a cell site or tower, where it provides a splice or connection point between the backhaul network and the cell site or tower.
The Rapid FFB divides functionally into feeder cable components and drop cable components, as shown in
Feeder Cable Components—include the RapidReel, the feeder cable, and a compression
nut assembly for securing the feeder cable after it is unwound.
