5.2. 250-mm Coated Fiber
5.3. 2.0- to 3.0- mm LooseJacketed Cable
5.4. 900- mm Easy Strip or Semi- Tight Buered Fiber
Read these instructions thoroughlybefore assembling
the connector kits.
All numerical values in this instruction sheet
are in metric units. Dimensions are in
millimeters Figures are not drawn to scale.
Reasons for reissue of thisinstruction sheet are
provided in Section 6, REVISION SUMMARY.
2. DESCRIPTION (See Figure 1)
Each connector kit consists of a connector assembly,
strain relief, inner eyelet, crimp eyelet, black tubing,
and clear tubing. Each kit is also suppliedwithabare
buer bootand small tubing to compensate for small
diameter cable. Also included, assembledonto the
connector, is a ferrule protective cover for the ferrule
(front of connector) andaplunger protective cap for
the plunger (rear of connector).
3. SAFETYPRECAUTIONS
NEVER look into the end of terminated or
unterminated bers. Laser radiation is invisible
but can damage eye tissue.NEVEReat, drink, or
smoke when working with bers. This could lead
to ingestion of glassparticles.
Be very careful to dispose o berends properly.
The bers create slivers thatcaneasilypuncture
the skin andcause irritation.
DO NOT use defective or damagedcomponents.
Replace them with newcomponents.

A. Preparing 900-mm Bare Buered Fiber(Figure 2)
1. Slide the bare buer boot (smalldiameter end
rst) over the buer. See Figure 2, Detail A.
2. Remove the ferrule protective cover and the
plunger protective cap from the connector
assembly. Keep the cover; discard the cap.
3. Push the connector into the holder of the cable
holder assemblywith the ferrule protective cover
facingoutward. See Figure 2, Detail B. Make sure
that the connector buttsagainst the lip of the arm
of the cableholder. Slide the berinto the channel
marked “BUFFER” on the cableholder. Make sure
that the tip of the buer buttsagainst the end of the
channel.
4. Mark the buer at each cross--slot of the
channel. See Figure 2, Detail B. Remove the buer
from the cableholder.
5. Using the strip tool, strip the ber to the rst
mark. It is recommendedholding the strip tool at
an angle to the berand stripping the ber in three
sections. See Figure 2, Detail C. Clean the ber
with an alcohol berwipe to remove the ber
coating residue.
Before using the strip tool, make sure that the “V”
opening is clean; otherwise the bercould break.
Only use isopropyl alcohol on the tool.
B. Cleaving (Figure 3)
1. Open the ber clamp of the beroptic cleaver.
Press the button,and slide the carriageback
(toward the ber clamp). Then move the ber slide
back until it stops.
2. Place the stripped berinto the slot so that the
end of the buer is at the 8--mm marking. See
Figure 3, Detail A.
3. Whileapplying pressure on the buer, carefully
slide the ber slide forward (toward the carriage)
until it stops. See Figure 3, Detail B.
4. Gently close the ber clamp, and slide the
carriage forward. DO NOT touch the button while
sliding the carriage. See Figure 3, Detail C.
5. Open the ber clamp, and move the ber slide
back until it stops.
6. Remove the cleaved ber, and properly dispose
of the scrap ber.
DO NOT attempt to clean the ber after it has
been cleaved.
C. Crimping (Figures 4 and 5)
1. Open the cable clamp of the cableholder, and
hold the buer (with the cleaved end o ber facing
the connector) inside the clamp. Pull the end of the
ber even with the front of the arm of the cable
holder, andholding the buer in place, close the
clamp. See Figure 4, Detail A.
2. Carefullyinsert the berinto the plunger of the
connector assemblyuntil the berbottoms against
the internal ber. Make sure that the remaining
mark on the buer enters the plunger. The
resultantbend in the buer shouldhold the ber
against the internal ber. See Figure 4, Detail B.
It is important that the berbottoms against, and
remains against, the internal ber. If the mark
doesnotenter the plunger or if the berdoesnot
seem to bottom against the internal ber, the
ber may be caught on internalguides. Rotating
the connector andbacking the berout a small
amountand re--entering may help. However, if
the mark willnotenter the plunger, the ber must
be re--stripped.

A. Preparing 900- mm Easy Strip or Semi- Tight
Buered Fiber(Figure 12)
1. Place the inner eyelet, smallend rst, inside the
clear tubing so that the ange o nner eyelet is
against the end of the tube. See Figure 12,
Detail A.
2. Slide the strain relief (long), clear tubing (with
inner eyeletinside), and crimp eyeletonto the
cable. See Figure 12,Detail B.
3. Remove the ferrule protective cover and the
plunger protective cap from the connector
assembly. Keep the cover; discard the cap.
4. Insert the small (white) tubinginto the connector
plungeruntil the tubingbottoms. See Figure 12,
Detail C.
5. Push the connector into the holder of the cable
holderwith the ferrule protective cover facing
outward. Make sure that the connector butts
against the lip of the arm of the cableholder. See
Figure 12,Detail D.
6. Slide the berinto the channel marked
“BUFFER” on the cableholder. Make sure that the
tip of the berbuttsagainst the end of the channel.
See Figure 12,Detail D.
7. Mark the ber at each cross--slot of the channel.
See Figure 12,Detail D. Also, placeamark on the
buer at the end of the channel.Remove the ber
from the channel.
8. Using the strip tool, strip the 250--mm ber
coatingandbuer back to the rst mark. It is
recommendedholding the tool at an angle to the
berand stripping the coating in three sections.
See Figure 12,Detail E. Clean the berwith
an alcohol berwipe to remove the ber coating
residue.
Before using the strip tool, make sure that the “V”
opening is clean. I t is not clean, the bercould
break. Only use isopropyl alcohol to clean the
tool.
9. Using the strip tool,apply slightly less pressure
thanwhen stripping125-- mm ber, and strip the
buer only (leave the 250-- mm ber coating in
place) to the second mark. Practice this rst.
10. Mark the 250-- mm ber coating at the shoulder
of the 900-- mmbuer. Strip the buer to the third
mark.
B. Cleaving (Figure 13)
1. Open the ber clamp of the beroptic cleaver.
Press the button,and slide the carriageback
(toward the ber clamp). Then move the ber slide
back until it stops.
2. Place the stripped berinto the slot so that the
end of the buer is at the 8--mm marking. See
Figure 13,Detail A.
3. Whileapplying pressure on the buer, carefully
slide the ber slide forward (toward the carriage)
until it stops. See Figure 13,Detail B.
4. Gently close the ber clamp, and slide the
carriage forward. DO NOT touch the button while
sliding the carriage. See Figure 13,Detail C.
5. Open the ber clamp, and move the ber slide
backuntil it stops.
6. Remove the cleaved ber, and properly dispose
of the scrap ber.

DO NOT attempt to clean the ber after it has
been cleaved.
C. Crimping (Figures 14,15,and16)
1. Open the cable clamp of the cableholder, and
hold the ber (with the cleaved end facing the
connector) inside the clamp. Pull the end of the
ber even with the front of the arm of the cable
holder, andholding the ber in place, close the
clamp. See Figure 14,Detail A.
2. Holding the 250--mm ber coating, carefully
insert the berinto the plunger of the connector
assemblyuntil the berbottoms against the
internal ber. Make sure that the second mark on
the coatingenters the plunger. The resultantbend
in the ber shouldhold the beragainst the internal
ber. See Figure 14,Detail B.
Also, the ber coating must enter the small tubing
thatwasinstalled in Step4of Paragraph 5.4.A.
Make sure that the start of the ber coating is not
caught on the entry of the small tubing.
It is important that the berbottoms against, and
remains against, the internal ber. If the mark
doesnotenter the plunger or if the berdoesnot
seem to bottom against the internal ber, the
ber may be caught on internalguides. Rotating
the connector andbacking the berout a small
amountand re--entering may help. However, if
the mark willnotenter the plunger, the ber must
be re--stripped.
Make sure that the berdoesnotpull rearward
from the contact (with the internal ber) during
the crimping operation.
When feeding the ber into the connector, hold
the ber of the bercoating to ensure that the
ber feeds into the connector. If the ber is
gripped by the buer tube, the ber will slide
rearwards into the buer tubeand willNOT
contact the internal ber.
3. Squeeze the handles of the hand tooluntil the
ratchet releases. Allow the handles to open fully.
Slowly close the handlesuntil you hear three clicks
from the ratchet.
4. With the connector assembly in the cable
holder, position the ferrule protective cover in the
upper cavity of the frontdieand the plunger in the
upper cavity of the reardie. It is importantto make
sure that the tip of the plunger sits in the channel
of the reardiewith the protrudingdisk of the
plungerat against the wall of the cavity. If the
plungerisnotpositioned correctly, it will be
crushedwhen the tool is actuated. See Figure 15,
Detail A.
The arrows marked on the front die indicate the
direction that the ferrule protective cover must be
pointing when the connector is positioned in that
cavity. For proper placement, andtoavoid
damage to the ber, the direction of the arrows
must be observed. Refer to Figure 15, Details A
and B.
5. Gently push the ber toward the connector to
make sure thatthe ber is stillbottomed, then
slowly squeeze the toolhandles togetheruntil the
ratchet releases. Allow the handles to open fully,
and remove the connector assembly from the dies.
6. Position the plunger of the connector assembly
in the rst (smallest) cavity of the frontdiewith the
shoulder of the plungeragainst the edge of the
groove in the dieand the ferrule protective cover
pointing in the direction of the arrow. See Figure
15,Detail B.
7. Slowly squeeze the toolhandles togetheruntil
the ratchet releases. Allow the handles to open
fully, and remove the connector assembly from the
die.
8. Slide the clear tubingwith the inner eyelet
against the end of the plunger. Slide the crimp
eyelet over the clear tubingandagainst the rear of
the connector. See Figure 15,Detail C.
9. Position the large diameter end of the crimp
eyelet in the last (largest) cavity of the frontdie
with the ferrule protective cover pointing in the
direction of the arrow. See Figure 16,Detail A.
Slowly squeeze the toolhandles togetheruntil the
ratchet releases. Allow the handles to fullyopen.
10. Position the smalldiameter end of the crimp
eyelet in the middle cavity of the frontdiewith
ferrule protective cover pointing in the direction of
the arrow. See Figure 16,Detail B.
11. Slowly squeeze the toolhandles togetheruntil
the ratchet releases. Allow the handles to open
fully, and remove the connector assembly from the
die.
12. Open the cable clamp of the cableholder, and
remove the buer (cable) from the clamp. Slide the
strain relief over the plungeruntil it buttsagainst
the connector. See Figure 16,Detail C.
13.Remove the connector assembly from the
cableholder.
The assembly procedure for 900-- mmeasy strip or
semi--tightbuered ber is now complete.
