1. INTRODUCTION
The MT--RJ jack kits listed in Figure1are designed to
terminate 900- m tightbuered optical ber. The
jacks must be used with 125-
m multimode ber
optic cableonly. 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.
Reasons for reissue of thisinstruction sheet are
provided in Section 6, REVISION SUMMARY.
The patch paneljacks t into adapter plates or patch
panels for use inarack-- or wall--mountenclosures or
enclosures havinganadapter plate or patch panel.

The workstationjacks can be used in faceplates or
walloutlets for use on wallboxes that are at least
50.8 mm [2 in.] deep. The workstationjacks can be
installed using the SL jack housing (includedwith the
kit) or Parallel Dress Clip1374206--1 (simplex) or
1374205--1 (duplex) shown in Figure 1.
For available adapter plates, patch panels,
enclosures, faceplates and wall outlets, and
installation instructions, refer to 408--8844.
2. DESCRIPTION (Figure 1)
Each patch paneljack kit contains six MT--RJ jack
module assemblies (each with protective cover), an
icon wheel,900-- m berguide (black), and two
actuation keys.
Each workstationjack kit containsone MT--RJ jack
module assembly (with protective cover), SL jack
housing,900-- m (black) berguide,jack boot, and
an actuation key.
The jack kits are shipped with the protective
covers installed onto the jacks. Keep protective
covers in placeuntil ready for connection.
Each jack has two channelsdesignated (on the top of
the jack) with “A” and “B.”
3. ASSEMBLY PROCEDURE
ALWAYS weareye protection when working with
optical fibers. NEVER look into the end of
terminated or unterminated fibers. Laser radiation
is invisible butcandamageeye tissue.
NEVEReat, drink, or smoke whenworking with
fibers. This could lead to ingestion of glass
particles.
During assembly, keep kit components and tools
as clean as possible to avoid contamination in
the optical interface.
3.1. Tools and Materials

preparation, assembly, inspection,and maintenance
of the assembly. Follow the operating instructions

3.2. Preparation
A. Stripping the Cable
1. For workstation jacks,slide the jackboot(small
diameter end rst) onto the ber.
IMPORTANT —For correct system polarity, Channel“A”
must be connected to Channel “B” andChannel “B”
must be connected to Channel “A” on any cable run
or cable assembly (including fiberoptic equipment).
Refer to Figure 2.
2. Using the beroptic combination strip tool, strip
the cable jacket to expose approximately381 to
508 mm [15 to 20 in.] o ber. Trim the strength
members even with the jacket.
3. Using the micro--strip strip tool, strip the ber to
35 to 37 mm [1.38 to 1.46 in.].

4. Clean the strippedportion of the berwith an
alcohol berwipe or lint--free tissue moistenedwith
isopropyl alcohol greater than91% (99% preferred)
to remove the ber coating residue. DO NOT touch
the strippedportion of the ber 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 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
endof the buer is at the 6--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. If the berdoesnot cleave,
repeat the process startingwith Step3of
Paragraph 3.2.A.

Fibers musthaveaquality cleavebefore
terminating to the jacks. To ensure that the
cleave tool is producing quality cleaves, it is
STRONGLY RECOMMENDED to inspect at least
one fiber cleaveperdayaccording to the
following:
1. Fit the bare fiberadapter onto the universal adapter;
thenassemble the universal adapter onto the microscope.
2. Using the microscope, inspect the fiber for a quality
cleave. Refer to the instructionspackaged with the
microscope kit) for operating procedures andsafety
precautionsconcerning the microscope.
DO NOT attempt to clean the fiber after it has
been cleaved.
IMPORTANT—Fibers must be terminated as soon as
the cleavingandinspection process is complete;
otherwise, damage to the fibers could result.
Procedd to Paragraph 3.3.
3.3. Termination
DO NOT use build--up tubes, fan--out kits, or
breakout kits on the fibers, and DO NOT use
loose tube fibereasy--strip fiber.
IMPORTANT—For correct system polarity, Channel“A”
must be connected to Channel “B” andChannel “B”
must be connected to Channel “A” on any cable run
or cable assembly (including fiberoptic equipment).
Refer to Figure 2.
Proceed as follows:
1. Holding the jack or placing the jack onaclean,
at surface (the protective cover helps to keep the
jack stabilized), slide the berguideonto the back
of the jack. See Figure 4.
The fiberguide is marked with the fiber size.
Make sure that the marking on the fiberguide
corresponds with the fiber size being used.

2. With the handle of the actuation key pointed
toward the top of the jack, insert the key (pointed
end rst) into the key hole for Channel A until it
stops (the entire key portion must be inside the
hole). See Figure 5. DO NOT force the key. With
the key in thisposition, the berhole is “closed.”
3. Slide the prepared beronto the slot of the ber
guideandinto the berholeuntil the ber stops.
Refer to Figure 5.
4. Whilelightly holding the ber in place, SLOWLY
rotate the key handle 90 (one--quarter turn)
toward the outside of the jack. See Figure 6,
Detail B. With the key in thisposition, the berhole
is “open.”
Ensure that the key is rotated ONLY one--quarter
turn; otherwise, the fiberhole will be partially
open,and the fibercannot be inserted.

5. Insert the ber furtherinto the berholeuntil it
bottoms. See Figure 7, Detail A. If the ber stubs
whileinserting it into the berhole, slightly turn the
ber, and continuetoinsert the berinto the hole.
The ber is fullyinserted into the berholewhen
the strippedportion of the ber is inside the jack.
6. Hold the ber in place usingenough pressure to
createaslightbow in the ber, thenSLOWLY
rotate the key handle 90 (one--quarter turn)
toward the inside of the jack. DO NOT “ip” the key
handle.Refer to Figure 7, Detail B. The ber is
now terminated to the jack.
7. Remove the key from the jack.
If preferred,usethe visual fault locator to confirm
that the fiber is fully inserted into the fiberhole.
When the fiber is properly inserted, the laser (or
LED) lightwill diminish in the target area of the
jack. Refer to Figure 8.
If using the visual fault locator, avoid
contamination to the ferrule end face. Make sure
that the protective cover remains clean when
removed,and thenbefore proceeding, re--install
the protective coveronto 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 AVOIDPERSONAL INJURY, wear eye
protection.
8. Repeat the assembly procedure for Channel B.

9. Carefullyslide the berguide at least 76 mm
[3 in.] away from the jack, then carefully route the
berout of the slot in the berguide. Keep the
protective cover on the jack if notinstalling the jack
immediately.
To avoid tension on the fiber, it is important to
slide the fiberguide away from the jack before
routing the fiberout of the fiberguide.
10. For workstationjacks, check to make sure that
the bers are not twisted, then slide the jack boot
over the elementhousing of the jack until it butts
against the shoulder. See Figure 9.
It is important that the FIBERS ARE NOT
TWISTED before installing the jack boot.
