CHAPTER 2: Introduction
2. Introduction
2.1 Description
Because individual fiber optic cable strands have an extremely small diameter, to
terminate the cable you must first enclose each strand in protective tubing. Once
the cable is enclosed, you can then add fiber optic connectors, such as SC, to each
enclosed cable.
The Buffer Tube Fanout Kits are specifically designed to terminate 6- and 12-
fiber buffer tubes. Perfect for users who want to field-install connectors, the kits
provide a compact, easy-to-install fanout solution. No additional hardware or space
other than that required for terminating tight-buffered cables is required. With
these kits, you don’t even need epoxy!
The Kits feature a 900-µm fanout assembly that is color-coded to match the fiber
color scheme. The fanout assembly is available with 6- or 12-fiber units in lengths
of 25 or 36 inches (63.5 or 91.4 cm). These different lengths give you the flexibility
you need for a variety of hardware options.
You can install the 6-Fiber Buffer Tube Fanout on 2.4-mm buffer tubes or the
12-Fiber Buffer Tube Fanout on 3.0-mm buffer tubes for indoor applications. The
Buffer Tube Fanouts branch the fibers from a buffer tube into individual fibers
protected by 900-µm PVDF protective tubing. You can then install connectors on
the fiber according to your hardware interface requirements.
One Buffer Tube Fanout is required for each 6- or 12-Fiber Buffer Tube. Please
read the installation instructions in Chapter 3 before assembling the Buffer Tube
Fanout.

2.2 Precautions
WARNING
Wear safety gloves to protect your hands from chemicals and accidental
injury when handling sharp-bladed tools.
Wear safety glasses to protect your eyes from accidental injury when
handling chemicals and cutting fiber. Pieces of glass fiber are very
sharp and can damage the cornea of the eye.
CHEMICAL PRECAUTIONS: Contains hydrocarbons. If ingested, DO
NOT INDUCE VOMITING. Call a physician immediately. KEEP OUT OF
THE REACH OF CHILDREN.
CAUTION
Fiber optic cable is sensitive to excessive pulling, bending, and
crushing forces. Consult the cable specification sheet for the cable you
are installing. Do not bend cable or buffer tubes more sharply than their
minimum recommended bend radius. Do not apply more pulling force to
the cable than specified. Do not crush the cable or buffer tubes or allow
them to kink. Doing so may cause damage that can alter the
transmission characteristics of the cable—the cable may have to be
replaced.

3. Installation
3.1 Preparing the Cable
CAUTION
Read the cable manufacturer’s sheath-removal instructions. Some
cable-stripping procedures may call for a slightly longer length at the
end of the cable to allow for cable core (buffer tube) damage caused
when accessing rip cords, etc. Be sure to add such length (typically 6 to
10 inches) to the strip length in Step 2, below.
You can assemble a Buffer Tube Fanout any time after you’ve removed the cable
sheath and cleaned the buffer tubes.
Installation factors such as the length of cable slack available, the location of
terminating hardware, and the question of storing buffer tube slack as opposed to
cable slack, can dictate when and where you choose to mount the cable end and
assemble the Buffer Tube Fanout.
Figures 3-1 and 3-2 illustrate two typical installation options.
Option 1 (Refer to Figure 3-1)
1. Prepare the cable end.
2. Route the cable end to a work surface.
3. Assemble the Buffer Tube Fanout.
4. Mount the cable on the hardware, and route the Buffer Tube Fanout and
tubes inside the hardware.
5. Install the Buffer Tube Fanout in the hardware.
