Product Purpose and Description
CMPH Exterior. The exterior of the CMPH consists of a nonmetallic, two-piece, rectangular, above-grade OSP enclosure that offers
easy installation, superior structural strength, 360_ technician access,
generous cable storage capacity, and protection against corrosion, floods,
fire, weather, soil, insects, intrusion, dents and impact for fiber-optic
cable splices and customer service drops in FTTP and FTTC (Fiber to the
Cell Site) deployments. The two exterior pieces of the CMPH are the base
and the dome. The enclosure base has ribbed walls, internal, dual-purpose, molded-in, channel grooves (which accept most metallic stakes as

well as the vertical channels of the internal framework, see Figure 2), an
open top, and an open bottom. Easy replacement installations and easy
underground cable access is provided via the open base bottom. The top
piece of the CMPH is the locking dome, designed to overlap the base for
a flood-protective bell-jar effect.
CMPH Interior. The interior of the CMPH consists of an internal framework which supports either one, two, or three CFDP206-EL08
pedestal fiber organizers mounted in the frame (hereafter referred to as
the “backboard” or “CFDP”). Each fiber organizer is enclosed and secured with two large locking doors, one on the CO side and the other on the
customer side, that separate the drop connections from the CO feed connections. Up to 24 connections can be made with SC or FC-type pre-terminated
cables at the fiber organizer’s interconnect bulkhead adapters (8 per fiber organizer). Feed side cables may be either a pre-terminated type connected directly to the CO side of the bulkhead, or a loop-through or stub-end cable
requiring sheath removal, attachment, and splicing in the provided splice
tray. Connectorized fan-outs or pigtails are spliced to the CO fibers and terminated at the bulkhead. Three-meter long SC or FC-type pigtails are available
from Charles Industries. Customer side cables are typically a pre-terminated
type with an SC or FC connector at the fiber organizer , and these connectors
are routed and inserted into the corresponding-numbered adapters for each
Customer line placed in service. Provided with any additional fiber organizer
ordered is a 3/4” diameter split tube to facilitate feed fiber transport from the
first fiber organizer to the second and third fiber organizers (Note: a minimum
fan-out or pigtail length of 60” is required). Labels are provided on the inside
at each door and near the bulkheads for connector-to-adapter matching. The
fiber organizer also enables technicians to route, bond, and attach various
cables, tubes, splice trays, fiber management D-clips, splitters or other
equipment, if needed. The bonding plate enables grounding and bonding
connections either inside the fiber organizer’s locked compartment or
outside the fiber organizer for line maintenance and testing.

Product Mounting Type and Location
The CMPH is an above-grade enclosure, the base of which is typically
installed at the cell site or FTTP distribution point in the ground up to the
ground line indicator on the base. The ribbed or corrugated base walls provide excellent stability in most soil types. The dome mounts on the base and
protects all equipment installed or mounted inside the CMPH. The internal
CFDP fiber organizer, where all cable preparations are performed, mounts
to sturdy framework secured to the base. After cable installation is complete, the fiber organizer doors are secured to protect all cabling and connections, then the outer dome is installed on the base for further protection.
Base stake mounting is accomplished via molded channel grooves, which
are located at the center of each interior base side wall. These grooves accept most new and existing enclosures’ mounting stakes.
- CAUTION Perform all bonding and grounding prior to making any communications
Figure 3. Fiber Organizer Doors Open on CMPH-IT1
For information regarding other installation types or applications, or
cable deployment types, contact Charles Industries (see Part 3).
- CABLE DAMAGE WARNINGS Be careful not to damage any buried cables or service wires while digging either
to expose cables or to prepare a hole or trench, or while driving stakes.
Buffer tubes and fibers are sensitive to excessive bending, pulling, and crushing
forces. To avoid kinking of buffer tubes and fiber damage or breakage, exercise
great care when working with fiber, and do not exceed or violate minimum bend
radius requirements for fibers, buffer tubes, and cables.
The tables that follow group the installation steps per the task or procedure type to enable the installer or technician to quickly locate the desired
instruction set (Paragraph 1.1 lists the table types). Note :the entire document instruction set assumes the following applications and cable configurations.
- GROUNDING WARNINGS Always follow local codes and company practices for performing proper cable
and site bonding and grounding, and perform all bonding and grounding prior
to other electrical, fiber, and communications connections.
Application presumptions
Site Cable Configuration or Deployment - The fiber cable deployment is a
CO or feed cable in a stub-in configuration (though not described in these
instructions, these pedestals support loop-through applications and preconnectorized feed cables, as well).
Trench Setup - A cable trench is already present and open, or backfilled with
the feed cable readily available.
Feed Cable Type or Design - The CO/feed cable is a loose buffer tube-type,
typically a 24-fiber cable (two tubes of 12 fibers each). Note: the CMPH accommodates most cable types.
Drop Cable Type - Drop cables are typically SC or FC-type preconnectorized cables. Note: the CMPH accommodates most cable types.
Transportation Tubing - Protective, flexible, transportation tubing is provided for internal transport of 900-micron fan-out feed fibers, if fan-outs are
used (one tube provided).
Cable Management clips - Cable management D-clips (rings) are provided for
internal fiber routing and management when 2mm jacketed pigtails are used.
- BODILY HARM WARNINGS Risk of serious eye damage! Never look into the end of a fiber optic line or circuit
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.
Shards and cleaved glass fibers are very sharp and can easily pierce the skin. Do not
let cut pieces of fiber stick to your clothing or drop in the work area where they can
later cause injury. Use tweezers to pick up cut or broken pieces of glass fibers and
place them in a container specifically meant for this purpose.
The corrugated metal or armor that may be present in the feed cable is very sharp
at the cut or exposed edges. Extreme caution should be taken to prevent personal
injury. Protective work gloves are recommended when handling armored cable.
Cable and fiber cleaning solvents may contain hazardous materials or harmful
ingredients. Always read and follow the MSDS when working with cleaning
solvents or products.

Optional - Replacement or rehabilitation mountings only. For applications
to replace old enclosures, continue with the steps in Table 3.
Determine and mark base installation location. To determine exactly where
to place the base in the trench, use the base itself as a positioning template by
placing it up over the top of the conduit, innerduct, or cables (route the cables
through the base) and lowering the base to the ground. Analyze the site and
position the base at its proposed final orientation and horizontal positioning in
the trench or hole and adjust accordingly. Mark this proposed final spot by
removing a shallow layer of top soil from around the outside perimeter of the
base about 2-4 inches wider than the base. Set the base aside.
13. h
14. h
Dig a hole for the base. Caution: Avoid damaging buried cables, wires,
innerduct, conduit or ground equipment whenever digging. At and within
the marked perimeter boundary, dig straight down to a depth of 9 inches. Do
not dig too deep.
15. h
Optional - Stake mountings only. For stake mounting applications, continue
with the steps in Table 2.
Put base in hole or trench and route cable(s) through base. Route the
cables and conduit or innerduct up through the bottom of the base, then put
the base in the prepared hole or trench.
Note: Ensure the base location allows technician access to the lock and any
equipment installed or to be installed in the CMPH.

17. h
Verify proper base depth. Before backfilling, verify the base is at the proper
depth (approx. 9" deep). Rest the base on solid or well-tamped soil when
measuring this distance. Verify the base ground line indicator is at the
final-grade ground line level. Remove, add, or tamp more soil as necessary.
18. h
Level the base. Verify that the base is level. Check the level in both
dimensions; front to back, and side to side. Make any needed base-bottom
soil adjustments to bring the base to a level position.
Prepare earth ground. Always follow local codes and company practice
when preparing earth ground and when grounding cables or equipment. If an
earth ground is not present at the CMPH site and local code or practice
requires an earth ground, prepare one now. Attach the earth ground to the
CMPH’s ground lug on the ground plate using a ground wire of proper gauge,
per company practice.
Backfill and tamp outside the base. With the base in place, backfill the
trench or hole outside of the base. While backfilling, tamp the soil or fill and
check the base level once or twice. Continue to add and tamp the soil until
3-5" gravel inside
the soil is at the base ground-line mark.

Place the red-plastic vapor barrier. Locate the provided, red-plastic,
vapor-barrier bag previously set aside, cut it open on all but one long edge to
make one large plastic sheet, verify it does not have any large holes in it (if it
does, seal them with duct tape), and place it into the base on top of the soil
fill. Completely cover the soil. Fit the bag around the cables, conduit, or innerduct, spread it outward from the center, and press all sheet edges downward
where they make contact with the base walls. Alternately, cut a hole or X" in
the center of the sheet, drop the sheet down over the centered cables or
conduit group, bring it all the way down to the tamped soil or fill, fit the sheet’s
inner hole edges around the cables or conduit, and spread it out as
underlined above. When installed properly, this sheet acts as a vapor barrier
and aids moisture run-off into the soil. Failure to use the plastic moisture-barrier bag on top of the soil significantly increases the risk of
condensation inside the enclosure.
Add gravel inside the base. Pour 3-5 vertical inches of company-approved
gravel (gravel minimizes condensation and drains well) into the base (to the
top base rib, or 2" below any innerduct or conduit opening) on top of the soil.
Use 5/8" (or less) diameter pea gravel, or clean, dry, non-porous, gravel rock
only (cut stone retains more moisture). Five 18-pound bags work well. Spread
out and level the gravel.
End of base installation - determine next procedure. If cable work will now
be performed, go to Table 4 and consult local practices and equipment
manufacturer instructions for the proper procedures. If further cable work will
NOT be performed at this time, go to Step 5 below to close the CMPH.

Verify hole or trench accommodates stake length. Lift the base and attempt to
place it back in place in the trench or hole. If the trench is deep enough to
accommodate the length of stake protruding from the bottom of the base, disregard
the remainder of this step. If the hole or trench is not deep enough to accept the
stakes, and the weight of the base is not enough to drive the stakes the length
needed to allow the base to rest at its proper depth, then once again use the base
as a template to mark the exact stake locations in the ground where more soil must
be removed. Remove the base from the hole, and at the stake-hole indentations, dig
down just enough to accommodate the length of the stake.

Table 2. Installing the CMPH with New Charles Stakes
Charles offers some CMPH models that include 2 mounting stakes (either 30", 36", or 42" long).
All stakes have identical hole patterns. This table describes how to install these models.
Attach stakes to grooves in base. Set the base on the
ground or a raised surface to access the grooves through
the base bottom. On the inside of the base, remove the nuts 1.125"
and washers from the bolts (which are 4" apart) that secure
the frame channels in place. On the mounting stake, the
distance between the first and third hole down from the top
of the stake is 4". Insert the top of the stake into the base,
rotate the stake so it will fit properly into the base groove (so
the perimeters match), align the stake holes with the bolts in
the base, and set the stake in place in the groove. Re-install
the lock washers and nuts that were removed to secure both
the mounting stake and frame channel in place. Repeat for
the other stake.

7. h
Remove the old enclosure. Completely remove the existing enclosure.
Protect cables and connections. Per company practice, wrap the existing
splice as tightly as possible without damaging the wire (fiber) connections.
Analyze condition of existing mounting stakes. Inspect the existing
mounting stakes for possible re-use. If they are deteriorated, bent, out of
alignment, or have a hole pattern that will not work with the Charles CMPH
base, carefully remove the stakes and install new ones per company practice
(consult Table 2 if desired).
Optional - remove the CMPH’s horizontal splice bars and/or ground
bracket. Determine if it will be necessary to temporarily remove any of the
CMPH’s internal, horizontal, supportive splice bars or brackets in order to fit
the existing cabling, connections, splices, and equipment into the CMPH
during the base installation. After base installation, re-attach the bars and
brackets (Step 10).
Section LT-CMP-HIT-801
8. h
Set base in place. Lift the base over the existing cabling and equipment, and
route the wrapped splice and all equipment up through the base bottom while
lowering the base to the bottom of the hole. If the existing stakes were used,
verify they are inside the base. If new stakes were attached to the base, insure
the hole accommodates them. Perform Steps 17-18 of Table 1 for the proper
base depth and level.
9. h Attach base to re-used stakes. Remove the nuts and washers from the 4
bolts located inside the CMPH base that secure the frame channels in place (2
bolts on each side, 4" apart). Manipulate the base and/or stake tops so the
re-used stakes fit into the preformed stake grooves in the base walls. Align the
base bolts with the stake holes, and re-attach the washers and nuts onto the
bolts. Firmly tighten nuts.
10. h Attach cables to bars and brackets. If the splice bars or brackets were removed,
re-install them now in the best positions to support (and ground) the equipment. Per
company practice, attach or mount all cables and equipment to the internal
framework (bars, brackets) of the CMPH. Re-attach any grounding, bonding, and
cable connections previously unattached to remove the old enclosure.

Cut to length then remove buffer tube. Buffer tube slack is typically coiled
inside the fiber basket, and a length of buffer tube is typically removed from the
tube’s stub end to expose the fiber that will be placed in the splice tray. These
buffer tube and exposed fiber slack or storage lengths are determined per
company practice and equipment manufacturer instructions. Determine the
desired length of buffer tube to store in the fiber basket (and also the desired
length of exposed fiber). Using local company procedures and tools, make a
mark at the desired tube cut-line, score the tube perimeter at the mark, and
remove the length of surplus tube and discard it.
Secure and protect non-working buffer tube(s). If the cable contains more
