Every situation is different, but as a general rule, it is typically easier to install
ber using a push and pull combination, rather than pushing or pulling by itself.
By using a combination push/pull method, installers have access to the ber
from both ends of the microduct when troubleshooting.
Recommended Installation Distances
Installation Manual
NOTE: If a ber gets stuck or snags during installation, the ber can be pulled back a couple inches from the end being fed into the duct and repulled past the bind point. Sometimes the connector needs to be rocked past a snag point by carefully alternating pushing and pulling from both
Whether pre-connectorized or not, here are a couple quick tips to use when installing pushable ber into the microduct.
These techniques have been used to install single ber, connectorized ber and multi-ber assemblies at distances in
excess of 500 feet.
●Never Remove Protective Cover from Pushable Connectors Prior to Installation
If the protective plastic cover is removed from a pre-connectorized pushable
assembly before you place the ber in the microduct, the connector acts as a sort of
“cheese grater” down the length of the microduct. It will shave off the inner liner and
then those particles bind around the ber. In some cases, this causes the ber to
become stuck and usually results in a broken ber.
●Pulling is Faster than Pushing
●Pull with Constant Pressure and Speed to Overcome Initial Friction
●Maintain the Same Feed and Pull Rate on Both Ends
FieldShield Microduct comes preinstalled with a nylon pull string that can handle pull strengths up to 50 lbs. When attaching
the pull string, never tie the pull string directly to the ber or connector. This will cause damage to or pull the connector off.
Also, never use tape over the string because the outside jacket of the ber is slippery enough that tape usually comes off
and clogs the microduct. Depending upon connector type there are two different methods to attach the pull string to the
pushable ber assembly.
Pre-Terminated Pushable SC and Blunt Drops
The rst method uses a nylon pulling eye that slides over the end of the assembly and works with blunt drops as well as
pre-terminated SC pushable assemblies.
Step 1: Slide the open end of the pulling eye over the plastic sheath of the SC Pushable Connector or the
blunt end of the assembly (Figure 1). Make sure to push the assembly all the way to the end of the pulling
eye and pull the pulling eye taut (Figure 2).
Installation Manual
Step 2: After the nylon pulling eye has been
slid over the end of the cable, simply tie
the pull string to the loop of the pulling eye
Note: When using SC Pushable Connectors,
make sure to cut back the excess string left
behind after tying the pull string to the pulling
eye. Failure to remove the excess string can
cause the connector to bind between the
string and the microduct during installation.

The second method uses a crimped pulling eye that was attached to the assembly during factory termination.
Installation Procedure
Step 1: Access the pulling eye by sliding the
connector’s protective sheath approximately 1”
towards the opposite end of the assembly, stopping at the metal crimp ring.
pulling eye and cut back the excess string left
behind.
Note: Do not to cut the string directly at the knot.
Leave about 2 to 3 mms of excess string next to
the knot.
Step 3: Make sure that the springs are staggered
one on top of each other then, push the
protective sheath over the connector and knot
from the pull string.
Note: Failure to stagger the springs increases
the width of the pushable connector, making it too
wide to pass tight corners.
Whether factory terminated or eld spliced, clean connectors are essential
for proper system operation. Even the smallest dust particle can cause
transmission problems, so for optimal network performance, inspect and if
necessary, clean all connectors and adapters prior to mating.
I.T.C…Inspect Then Connect!
ALWAYS inspect the connector rst thing with a clean ber scope inspect
the pair. Three types of contamination require different cleaning techniques.
The use of Chemtronics end face and bulkhead cleaning products and
techniques ensures a clean end face, no matter the type of contamination.
These are Cleareld recommended products/application. Use the product
you feel will complete your cleaning procedures. Create a “best practice” for
your company and follow those procedures.

**NOTE: It is NOT recommended to use IPA to clean the end-face.
Cleaning the end-face…but not just the end-face
• Place one wiping paper on QbE-2 FiberSafe™ Cleaning Platen. Figure 1
• Apply small amount of precision cleaner (about 1” in diameter) with Electro-Wash MX pen on to one end of the wipe. Figure 2
• Hold end face 90 degree. Adjust for APC connection by slightly tilting the
container or end face. Angle is correct when no drag is left on the end face.
Figure 3
• Draw end face from wet to dry part of the wipe 3 times. Use just enough
pressure to ensure complete contact between end face and the wipe.
• CLEAN THE FERRULE…Lightly moisten the ber optic swab
(2.5mm/38542F or 1.25mm/38040) by spotting a small amount (about 1”)
of Electro-Wash PX or Electro-Wash MX pen onto the QBE-2. Hold the
swab, 1 side down to the wetted area and hold for a count of 1-2-3-4-5.

Cleaning the mate through a bulkhead adapter AND the
adapter itself!
• Lightly moisten the ber optic swab(2.5mm/38542F or 1.25mm/38040)
by spotting a small amount (about 1”) of Electro-Wash PX or Electro-Wash MX pen onto the QBE-2. Hold the tip of the swab onto the
wetted area and hold for a count of 1-2-3-4-5.
• Insert the swab into the adapter to the connector, press lightly against
the connector, twist 2-3 times, remove and discard.
• Dry with a second dry swab.
• Inspect (re-clean if necessary) and test for signal strength.
• Use additional swabs to clean inside the actual adapter. Moisten swab,
like above, insert through hole and remove while twisting. Figure 6

method to clean “dirt” can lead to scratching of the end-face. Learn the
process of cleaning properly!
Step 1: Remove the white protective dust cap from the unassembled connector (Figure 1).
Note: The SC Pushable Connector has a keyed locking
feature that holds the inner housing to the connector and
aligns the ferrule when the two are correctly mated.
To properly mate the connector, the key on the inner housing
must bypass the ferrule alignment notch to properly lock into
place.
Step 2: Align the black mark on the inner housing with the
black line on the connector, then rotate the inner housing
45 degrees to offset the lock (Figure 2) and slide the inner
housing half way over the connector.
Step 3: Rotate counter-clockwise 45 degrees to realign the
inner housing and connector and push the inner housing onto
the connector until it snaps into place (Figure 3).
Step 4: Align the key on the outer housing with the black line
on the connector, then slide the outer housing over the entire
assembly until it snaps into place (Figure 4).
Step 5: Re-install the white protective dust cap (Figure 5).

Note: The jacket is removed using a score and
snap process. Make sure that the rotary tube
cutter blade has been adjusted so that it scores
the outside of the jacket, but does not entirely cut
through. Do not cut or nick the ber.

Step 3: Pulling from the cable, pull the 3mm jacket off in a straight line (Figure 3).
Step 4: Using a cleaning wipe and some Isopropyl alcohol, wipe clean the exposed 250um ber
(Figure 4).
Step 5: Cut a piece of 900um furcation tubing
6” longer than the desired breakout. Mark the
900um tubing 6” from the end of the cut (Figure
5). This 6 inch mark will tell you how far to insert
the 900um tubing into the 3mm cable.

Step 11: Allow the glue to dry, and then trim the
excess Kevlar strength members behind the
heatshrink (Figure 11).
Note: The CraftSmart Splice-On Connector can
now be installed per standard instructions to the
900um furcated ber.
These instructions detail the installation of 2, 6, and 12 ber 900um furcation upjacketing kits. Each kit breaks out 250um
bers from a multiber loose tube into individual 900um buffer tubes. The ber can then be terminated using the 900um

Installation Procedure
Step 1: Locate and setup your work surface as close to the patch panel location as possible. This will minimize the strip
length.
Step 2: Route the cable through the patch panel to the work surface.
Step 3: Measure backwards, from the end of the cable to the point at which it will attach to the patch panel, and add 39
inches (1 meter) to the length. Mark this length with a piece of tape. This is the strip point for the cable being
terminated.
Step 4: Strip the cable back to the tape mark.
Step 5: Secure the cable to the patch panel.
Step 6: Clean any dirt and/or gel surrounding the loose tube.
Step 7: Select the rst buffer tube and measure back 36 inches (90cm) and place a mark.
Step 8: Score the buffer tube and strip the loose buffer tube at the mark.
Step 9: Thread the heatshrink until it is ush with the end of the buffer tube and shrink in place.
Note: Be careful not to melt or distort the tube due to excessive heat.

• Lint Free Wipes
• Indelible Marker
• Buffer Tube Stripper
• Gel Cleaner
• Needle Nose Pliers
Step 10: Tape the buffer tube to the work surface with 2 inches (50mm)
overhanging the end of the work surface (Figure 1).
Step 11: Wipe all the gel from the exposed bers using a gel cleaner.
Step 12: Place the buffer tube in the bottom of the furcation kit. Using pliers, press the tabs of the crimping xture to hold
the loose tube.
Note: Crimp only enough to start to deform the tube. Twist and pull the terminal body to check if the crimp is
secure. The tube should not slip or move in the crimp xture.
Step 13: Tape the terminal assembly in the vertical position 3 inches (75mm)
to the side of the loose buffer tube (Figure 2).
Step 14: Untangle the bers and make sure they are completely free of gel lling compound.
Step 15: Talc the bers to facilitate the threading operation. Cup the talc in the palm of your hand and apply along the whole
length of the bers.
Step 16: Select the blue ber and thread 6 inches (150mm) into the blue tube
of the terminal assembly (Figure 3).
Repeat this procedure for the remaining bers, making sure the
color coded bers match the color coded 900um tubing.
Step 17: When all bers have been threaded, push the bers as a group until
the bers start to protrude from the ends of the buffer tubes.
Step 18: Gently pull the bers from the ends of the buffer tubing.
Figure 3
Note: Do not pull the bers taught. Leave sufcient slack so the bers are not stressed.
Step 19: Untape the buffer tube assembly and slide the assembly toward
the loose tube while pulling the bers from the end of the 900um tubing. If the bers twist, rotate the terminal assembly in the opposite direction of the twist (Figure 4)
• Please read and follow all fusion splicer manufacturer recommended procedures concerning splicing operation and
precautions.
• Safety glasses should be worn when handling cleaved bers. Cleaved bers are sharp and can pierce eyes, skin or
clothing.
• Never look into the end of a microscope or optical cable connected to an operating optical output device. Laser radiation
is invisible, and direct exposure can severely injure the human eye.
Note: Before starting this process, completely read through the entire installation document. If the splice machine you are
using has a tensile test option, be sure to shut this option off on your machine.
Step 4: Remove Install the dust cap with the
handle on to the ferrule (Figure 2).
Step 5: Carefully remove the ber protection cover
from the back side of the connector (Figure 3).
Do not to touch the stripped end of the ber or let
anything bump against it.
Note: The Fiber is already stripped, cleaned and cleaved to the exact
dimension needed.

Step 7: Following the splice machines
instructions carefully insert the splice holder with
the connector inside of the holder into one side of
the machine (Figure 5). Using extreme caution,
do not touch or bump the stripped ber against
anything.

Step 8: Insert the Strain Relief Boots narrow end rst on to the 900um ber that you will be splicing to.
Step 9: Insert the Fusion Splice Protection Sleeve on to the 900um ber after the Strain Relief Boot.
Step 10: Following the Fusion Splicer’s manufacturers recommendations strip the ber to length.
Step 12: Clean bare ber with clean wipe and alcohol.
Step 13: Cleave the bare ber to 10mm. If the cleave length is too long it will not be protected in the
Splice Protection Sleeve.
Step 14: Following the splice machines instructions carefully insert the splice holder with the 900um
ber into the opposite side of the machine. Using extreme caution, do not touch or bump the stripped
ber against anything.
Step 15: Following the Fusion Splicer’s manufacturers procedure splice the connector to the ber.
Step 16: Once the splicer has completed the process and you are satised with the results, carefully
slide the protection sleeve up to the ber holder and remove the ber and connector from the splicer.
Step 17: Slide the protection sleeve toward the
connector centering it over the stripped bare ber
splice (Figure 6).
Step 18: Insert the ber and protection sleeve
into the protection sleeve oven with the connector
all the way to one side of the oven keeping it out
of the oven as the best as you can (Figure 7). If
you cannot close the ovens cover then you can
lay the splice protection holder over the protection sleeve to help keep the heat inside.
Note: If the splice protection sleeve is
not shrunk down all the way then you can run the heat cycle again. You may
want to increase the ovens time duration
if this continues to happen.
