GENERAL
1.1 Document Purpose.
This document provides instructions for the fiber cable tech-
nician to properly perform fiber cable preparations, routings, splicing, terminations and
connections within the Charles Industries’ Fiber Distribution Point (CFDP
) EL series
of Pedlock
pedestals with 10” or 12” domes. (The CFDP EL series offers an interior
backboard designed for use in fiber applications where preconnectorized SC/APC or SC/
UPC connections are desired, such as at cell sites to service multiple wireless operators).
Figure 1 shows a dome-off interior-door-open view of a 10” dome CFDP10-EL18 mod-
el. The 12” models are identical except they support 24 drops. See Table 2 for
information on all models in this series, or call Charles Industries (see Part 3) to request
more information or literature.
- NOTE -
Hereafter all models in the series will be commonly referred to as the “CFDP” or “pedestal.”
Specific model numbers will be specified or referenced where important differences apply.
1.2 Document Status.
Print 3 updates Table 2. Print 2 updated the document title,
Paragraphs 1.1 and 1.3, Steps 1, 5, 16 and 29 of Table 1, Table 2 (added models with SC/
APC adapters and separates and lists pigtails as kits), and added Paragraph 1.4.
1.3 Product Purpose and Description.
The CFDP is an above-grade pedestal that of-
fers excellent OSP protection against floods, fire, dirt, weather, insects, and impact for
fiber-optic cable splices and customer service drops in FTTP deployments. This protec-
tion is achieved with a weather-resistant yet free-breathing interior enclosure that is
within the confines of a protective, exterior, buried-distribution-cable pedestal. The bot-
tom section of the pedestal is the base: a square-shaped, expanded-capacity, non-metallic,
locking, 2-piece, split base designed to open and easily install around conduit-fed cable
bundles or to accept less flexible cables. The top section of the pedestal contains a non-me-
tallic outer dome, which covers and protects an inner double-door enclosure, which in
turn protects the heart of the pedestal: the exclusive, versatile, and interchangeably-de-
signed, metallic, interior backboard. Two locking doors are provided on the CFDP EL
series, one on each side (CO-side vs. drop or customer side), to separate the drop connections
from the CO feed connections. On both sides of the backboard, quick and easy connections
are made with preconnectorized SC-type cables to SC-type adapters at the Interconnect bulk-
head at the top of the backboard. The other end of the SC-type cable (pigtail) should be spliced
to the feed cable within a provided splice tray. As an option, Charles provides three-meter-
long SC-type pigtails for feed cable connections (see Table 2 for details). The sturdy,
versatile, metallic backboard also enables technicians to route, bond, and attach various
cables, tubes, splice trays, splitters or other equipment. Grounding and bonding connec-
tions can be made either inside the locked interior compartment, or outside for easier line
maintenance and testing. Charles’ CFDP pedestals are designed to be installed in new
or replacement installations, to accommodate various soil and mounting applications as
well as various cable types and applications, to accommodate certain fiber slack situa-
tions, and to exceed Telcordia GR-771-CORE specifications.
1.4 Applications.
The CFDP Interconnect Pedestal is ideal for multi-tenant cell site,
campus or strip mall environments where the customer requires high-capacity fiber
bandwidth for wireless backhaul, private networks or data and video broadband services.
With a built-in SC/APC or SC/UPC adapter bulkhead, Interconnect pedestals facilitate
fast and easy provisioning of fiber services to the end customer’s fiber multiplexing
equipment. Fiber drops can be turned up, moved or disconnected on an “as needed” basis,
giving telecom service providers added flexibility in their efforts to provide broadband
voice, data, and video services to customers whose bandwidth requirements may change
seasonally or due to major events.
1.5 Product Mounting.
The CFDP pedestal base is typically installed at the cell site
or FTTP distribution point in a trench or hole in the ground up to the ground line indicator
on the base. The pedestal backboard, where all cable preparations are performed, mounts
to the base. Once all cable connections are complete, the inner doors are secured to pro-
tect all cabling and connections, then the outer dome is placed over and attached to the
base for further protection. The base contains holes or knockouts at the rear and both
sides that accept an optional, metallic, mounting stake or a pole-mount stake.
- CAUTION -
Perform all bonding and grounding prior to making any electrical and
communications connections.

CABLE INSTALLATION AND SPLICING
Table 1 helps the cable technician to perform all fiber feed and drop cable preparations,
routings, attachments, splicing, and connections, and presumes the following conditions:
Site Cable Configuration or Deployment
- The fiber cable deployment is a CO or
feed cable in a stub-end configuration
(though not described in these instruc-
tions, these pedestals support loop-through applications, as well)
.
Equipment Installation
- A CFDP
base has been properly installed at the de-
sired field site (for base installation information, see the pedestal base installation
document factory-attached to the base).
Trench Setup
- The trench is either dug and open, or backfilled with the feed cable
already placed and brought into the base bottom.
Feed Cable Type or Design
- The CO or feed cable is a loose-buffer-tube type with
single fibers.
Drop Cable Type
-
Drop cables are
SC/UPC or SC/APC-type preconnectorized
cables.
Transportation Tubing
- Protective, flexible, transportation tubing is provided
for the feed cable pigtails (two 3-feet long pieces).

- EYE DAMAGE WARNING -
Risk of serious eye damage! Never look into the end of a fiber optic line nor use a
magnifier in the presence of laser light or radiation. Always exercise caution when
installing, testing, or performing maintenance on live circuits. If eye exposure to
laser light or radiation has occurred or is suspected, immediately seek medical
treatment by a professional eye care physician.
- FIBER OR CABLE DAMAGE CAUTION-
Buffer tubes and fibers are sensitive to bending, pulling, and crushing forces.
Avoid buffer tube kinking and fiber damage: use care when working with fiber and
do not violate fiber, buffer tube, and cable minimum bend-radius requirements.
In cold environments, some loose tube cable designs may exhibit low temperature
induced signal attenuation when long lengths of buffer tubes have been exposed
and then stored. Contact the cable manufacturer concerning recommended
exposed buffer tube lengths in your installation area.
- WARNING -
Cable and fiber cleaning solvents may contain hazardous materials or harmful
ingredients. Always read and follow the manufacturer’s precautions, warnings,
and instructions when working with cleaning solvents or products.
Shards and cleaved glass fibers are very sharp and can easily pierce the skin. Use
tweezers to pick up cut glass fibers and place them on a loop of tape or in a
container specifically meant for this purpose. Good housekeeping is important.
Corrugated metal or armor that may be present in feed cables is very sharp when
cut or exposed. Exercise extreme caution to prevent personal injury. Use
protective work gloves when handling armored cable.

site and local practice requires an earth ground, prepare one at this time. Do not
connect
earth ground until the backboard is re-attached to the base.
Preparing the Feed or Branch Stub Cable
8.
Verify sufficient feed cable length.
Verify 9 feet
(approx.)
of cable,
from the ground line to the cable’s stub-end, extends up through
the pedestal base, and lift it up. Press the cable toward the rear
of the base so it will be at the CO or feed side of the backboard
(the side with fewer but larger rubber grommet ports), when it is
installed. See the base installation document for instructions on
installing the base and routing cables into the base.

Attach backboard.
(Skip this step if the
backboard is already installed.) First, pos-
ition the feed cable so it will be at the CO or
distribution side of the backboard (see
Figure 1). Then install the backboard to
facilitate marking the cable for the proper
cable sheath removal length. Align the
backboard’s support legs with the leg guides
in the base collar. Once the leg guides are
lined up, press down on the backboard until it
stops and the tab locks are engaged (audible

12.
Mark cable for sheathing
removal.
The cable sheathing
must be removed from the cable
stub to expose the fiber to be
spliced, but enough cable length
with sheathing must remain to hold
it in place against the backboard.
On the feed side of the backboard,
locate the T" cable tie-down
located directly above the chosen
grommet, pull the cable up until it is
almost taut, hold the cable against
the T, and mark a cut-line on the
cable midway between the T and
cable strength member clamp
above it (approximately 7 inches
above the top ot the base collar).
