1. INTRODUCTION
The MT–RJ jack kits listed in Figure 1 are designed to
terminate 250–
m
m coated optical fiber. The jack kits
must be used with only the optical fiber size given in
Figure 1. Read these instructions thoroughly before
assembling the jack kits.
These jack kits cannot be used with build-up
tubes, loose tube fiber, easy-strip fiber, fan-out
kits, or breakout kits.
Dimensions in this instruction sheet are in metric
units [with U.S. customary units in brackets].
Figures are not drawn to scale.
The jacks fit into adapter plates or patch panels for
use in a rack– or wall–mount enclosures or
enclosures having an adapter plate or patch panel.
The jacks can also be installed in wall outlets for use
in wall boxes using Parallel Dress Clip 1374206–1
(simplex) or 1374205–1 (duplex) shown in Figure 1.
For available adapter plates, patch panels,
enclosures, and wall outlets, and installation
instructions, refer to 408-8844.
Reasons for reissue of this instruction sheet are
provided in Section 6, REVISION SUMMARY.
2. DESCRIPTION
(See Figure 1)
Each jack kit contains six MT–RJ jack module
assemblies (each with protective cover), an icon
wheel, 250–
m
m fiber guide (beige), and two actuation
keys.
The jack kits are shipped with the protective
covers installed onto the jacks. Keep protective
covers in place until ready for connection.
Each jack has two channels designated (on the top of
the jack) with “A” and “B.”
3. ASSEMBLY PROCEDURE
ALWAYS wear eye protection when working with
optical fibers. NEVER look into the end of
terminated or unterminated fibers. Laser radiation
is invisible but can damage eye tissue. NEVER
eat, drink, or smoke when working with fibers.
This could lead to ingestion of glass particles.
During assembly, keep components and tools as
clean as possible to avoid contamination in the
optical interface.

3.2. Preparation
A. Stripping the Cable
IMPORTANT
Ċ
For correct system polarity, Channel “A”
must be connected to Channel “B” and Channel “B”
must be connected to Channel “A” on any cable run
or cable assembly (including fiber optic equipment).
Refer to Figure 2.
1. Using the fiber optic combination strip tool, strip
the fiber to 31 to 33 mm [1.22 to 1.30 in.].

2. Clean the stripped portion of the fiber with an
alcohol fiber wipe or lint–free tissue moistened with
isopropyl alcohol greater than 91% (99% preferred)
to remove the fiber coating residue. DO NOT touch
the stripped portion of the fiber after cleaning.
B. Cleaving the Fiber
Fibers must be terminated as soon as the
cleaving and inspection process is complete;
otherwise, damage to the fibers could result.
1. Open the fiber clamp of the fiber optic cleaver.
Press the button, and slide the carriage back
(toward the fiber clamp). Then move the fiber slide
back until it stops.
2. Place the stripped fiber into the slot so that the
end of the buffer is at the 4–mm marking. See
Figure 3, Detail A.
3. While applying pressure on the buffer, carefully
slide the fiber slide forward (toward the carriage)
until it stops. See Figure 3, Detail B.
4. Gently close the fiber clamp, and slide the
carriage forward. DO NOT touch the button while
sliding the carriage. See Figure 3, Detail C.
5. Open the fiber clamp, and move the fiber slide
back until it stops.
6. Remove the cleaved fiber, and properly dispose
of the scrap fiber. If the fiber does not cleave,
repeat the process starting with Step 3 of
Paragraph 3.2.A.
Be careful to dispose of fiber ends properly. The
fibers create slivers that can easily puncture skin
and cause irritation.

Fibers must have a quality cleave before
terminating to the jacks. To ensure that the
cleave tool is producing quality cleaves, it is
STRONGLY RECOMMENDED to inspect at least
one fiber cleave per day according to the
following:
1. Fit the bare fiber adapter onto the universal adapter;
then assemble the universal adapter onto the microscope.
2. Using the microscope, inspect the fiber for a quality
cleave. Refer to the instructions packaged with the
microscope kit) for operating procedures and safety
precautions concerning the microscope.

Proceed to Paragraph 3.3.
3.3. Termination
DO NOT use build-up tubes, loose tube fiber,
easy-strip fiber, fan-out kits, or breakout kits.
IMPORTANT
Ċ
For correct system polarity, Channel “A”
must be connected to Channel “B” and Channel “B”
must be connected to Channel “A” on any cable run
or cable assembly (including fiber optic equipment).
Refer to Figure 2.
Proceed as follows:
1. Holding the jack or placing the jack on a clean,
flat surface (the protective cover helps to keep the
jack stabilized), slide the fiber guide onto the back
of the jack. See Figure 4.
The fiber guide is marked with the fiber size.
Make sure that the marking on the fiber guide
corresponds with the fiber size being used.

hole). See Figure 5, Detail A. DO NOT force the
key. With the key in this position, the fiber hole is
“closed.”
3. Slide the prepared fiber onto the slot on the fiber
guide and into the fiber hole until the fiber stops.
See Figure 5, Detail A.
4. While lightly holding the fiber in place,
SLOWLY
rotate the key handle 90
_
(one–quarter turn)
toward the outside of the jack. See Figure 5,
Detail B. With the key in this position, the fiber hole
is “open.”
Ensure that the key is rotated ONLY one-quarter
turn; otherwise, the fiber hole will be partially
open, and the fiber cannot be inserted.
5. Insert the fiber further into the fiber hole until it
bottoms. See Figure 6, Detail A. If the fiber stubs
while inserting it into the fiber hole, slightly turn the
fiber, and continue to insert the fiber into the hole.
The fiber is fully inserted into the fiber hole when
the stripped portion of the fiber is inside the jack.
6. Hold the fiber in place using enough pressure to
create a slight bow in the fiber, then
SLOWLY
rotate the key handle 90
_
(one–quarter turn)
toward the inside of the jack. DO NOT “flip” the key
handle. Refer to Figure 6, Detail B. The fiber is
now terminated to the jack.
7. Remove the key from the jack.
If preferred, use the visual fault locator to confirm
that the fiber is fully inserted into the fiber hole.
When the fiber is properly inserted, the laser (or
LED) light will diminish in the target area of the
jack. Refer to Figure 7.
If using the visual fault locator, avoid
contamination to the ferrule end face.
Make sure that the protective cover remains
clean when removed, and then before
proceeding, that the protective cover is
re-installed onto the jack.
If the ferrule end face is touched or otherwise
contaminated, clean the end face with canned air
before re-installing the protective cover.
TO AVOID PERSONAL INJURY, wear eye
protection.
8. Repeat the assembly procedure for Channel B.
9.
Carefully
slide the fiber guide at least 76 mm
[3 in.] away from the jack, then carefully route the
fiber out of the slot in the fiber guide. Keep the
protective cover on the jack if not installing the jack
immediately.
