Admonishments

Important safety admonishments are used throughout this manual. The admonishments must be followed at all times. These warnings are flagged by use of the triangular alert icon (seen below), and are listed in descending order of severity of injury or damage and likelihood of occurrence.
Danger: Danger is used to indicate the presence of a hazard that can cause severe personal injury, death, or substantial property damage if the hazard is not avoided.
Warning: Warning is used to indicate the presence of a hazard that can cause severe personal injury, death, or substantial property damage if the hazard is not avoided.
Caution: Caution is used to indicate the presence of a hazard that can cause minor personal injury or property damage if the hazard is not avoided.

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.

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.

fiber
• Drop Cable Components—consist of two compression nut assemblies for securing drop
cables and either sliding adapter packs or splice trays for terminating the drop cables within the FFB.

The components called out are as follows:
• Outer Door—swings open to provide access to the interior of the box.
• Outer Door Latch—houses a door lock operated with a 216B key tool. It has a hole for an
optional padlock.
• Designation Label—provides an area to record the designation of drop cables.
• Door Grounding Wire—grounds the door to the main part of the box (which is in turn
grounded to the facility ground).
• Sliding Adapter Packs—transition between the feeder cable on the RapidReel and drop
cables. Depending on the fiber count of the feeder cable, the FFB may contain either 12 or 24 adapters.
• RapidReelTM— contains the spooled up feeder cable which is unspooled at the customer
site and routed to the connection point with the cable from the backhaul network. The RapidReel is locked when shipped and must be unlocked before the cable can be unwound.

• Radius Limiters—are guides for wrapping around the drop cables when installed. They
prevent the drop cables from being damaged by being bent too sharply.
• Grounding Studs—are used to fasten a two-hole grounding lug and grounding wire.
• Feeder Side Cable Portal—holds the compression nut assembly that is used to secure the
feeder cable after it is unwound.
• Drop Side Cable Portals—holds the compression nut assemblies used to secure drop
cables after they are installed. Multiple cables may enter through the same portal.
Figure 3 shows the splice-specific components of a Rapid FFB with splice trays on the drop
side. This unit also has an internal RapidReel fiber cable spool and feeder cable.
• Radius Limiters—are guides for wrapping around the drop cables when installed. They
prevent the drop cables from being damaged by being bent too sharply.
• Hook-and-Loop Straps—secure the splice trays to the RapidReel and allow the splice
trays to be easily removed from the RapidReel and returned to it after completion of splicing or other maintenance procedures.
• Splice Trays—are used to splice the feeder cable fibers to the drop cable fibers. The Rapid
FFB accommodates up to
two 12-fiber SC ribbon assemblies

2.1 General Recommendations

The site chosen for the installation must conform to all local codes and any permits required must be obtained prior to the start of installation. The location must be accessible and provide adequate parking for worker and vehicle safety. In addition, the installed FFB must not create a visual or physical obstruction to vehicular or pedestrian traffic. Sufficient space must be provided on all sides to facilitate FFB installation and maintenance.
Install a grounding system (not provided) that meets all local electrical codes. Check local codes for grounding system installation, use of clamps, wire size, and any other grounding requirements. Typically, a 2-hole grounding lug crimped to a #6 AWG solid copper wire is used to connect the FFB to a approved earth ground source as specified by local code or practice.

2.2 Wooden Utility Pole Mounting Procedure

Use the following procedure to mount the FFB on a wooden utility pole.
1. Obtain the following fasteners and tools:
• 3/8-inch x 2 inch lag screw suitable for exterior application
• Drill
• 9/32-inch drill bit
• 1/2-inch drill bit (optional depending on pole condition)
• 9/16-inch wrench
• 216B key tool (accessory)
The following fasteners are optional depending on the condition of the pole:
• 1/2-inch threaded rod (1), 1/2-inch nut (1), 1/2-inch flat washer (2), 1/2-inch lock washer (2)
2. Using the mounting bracket as a guide, mark the location of the bracket mounting holes on the pole as shown in
Figure 6.
3. Drill a 9/32-inch hole in the pole at each of the locations marked in step 2.
4. Secure the mounting bracket to the pole using the two 3/8-inch x 2-inch lag screws. Tighten lag screws securely.
