General Warning and Caution Statements
Danger: Avoid eye exposure to unmated connectors. Unmated connectors may emit invisible
laser radiation. Do not look directly into the end of a connector or adapter port. Do not inspect
with a magnifying device. To ensure safety, maintain caps on unmated connectors at all times.
Caution: Handle cables with care. Fiber optic cable stubs should be handled with care
throughout the installation procedure to avoid kinking and damage to cables.
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.
